Choosing filters for a monochrome camera means planning a complete imaging path: the filter size must fit your optical train, and each filter change affects how you capture a sequence. I rank the Astromania 1.25-inch wheel with LRGB filters first for buyers who want a wheel and core color set together, while the SVBONY SV133 is the larger-format pick for a 2-inch setup. The Alstar 2-inch LRGB set suits owners who already have a compatible wheel. The tradeoffs are practical: 1.25-inch filters keep the setup compact, while 2-inch components fit larger accessories; manual wheels cost you automation, and every wheel needs enough inward focus travel.

Key Takeaways
- The Astromania 1.25-inch wheel with LRGB filters combines the basic color-imaging set and a five-position manual wheel in one package.
- The SVBONY SV133 is the listed 2-inch wheel option, with five positions and a light-tight interior; confirm the adapters and camera connection suit your optical train.
- The Alstar LRGB set provides four 2-inch filters but no wheel, so it suits mono-camera owners who already have a compatible way to change filters.
- Both Astromania wheels require substantial inward focus travel: 20 mm for the LRGB bundle and 23 mm for the adapter-equipped model.
- The Cokin Traveller kit is designed for landscape photography, not monochrome-camera LRGB imaging, so its holder and graduated ND filters do not fill the same role as the astronomy products.

Astromania 1.25 inch 5-Position Filter Wheel with LRGB Filters Set
This is the most complete match for a mono-camera buyer starting with a compact imaging train: a manual five-position wheel arrives with luminance, red, green, and blue filters. That pairing avoids the extra step of sourcing an LRGB set separately, unlike the Alstar filters, which need a wheel, and the Astromania adapter model, which is sold as a wheel without a listed filter set. One position remains available beyond the four named filters, which gives some room for an additional filter.
The main constraint is fit. This option takes 1.25-inch filters and calls for 20 mm of additional focus travel, so buyers should check their telescope and camera train before choosing it. It is also manual: the description supports quick rotation, but gives no basis to expect computer-controlled changes during an imaging sequence. Compared with the larger SVBONY wheel, this is the more compact and bundled choice; it is less suitable for a 2-inch optical path or automated capture.
Pros:- Includes luminance, red, green, and blue filters with the wheel.
- Five positions leave one slot beyond the listed LRGB set.
- Aluminum construction and a manual rotation system support straightforward filter changes.
Cons:- Requires 20 mm of additional focus travel, which may rule out some optical trains.
- Limited to 1.25-inch filters and no motorization is specified.
Best for: Mono-camera users building a 1.25-inch LRGB setup who want the wheel and core filters in one purchase.
Not ideal for: Imagers committed to 2-inch accessories, needing automated filter changes, or working with a telescope that cannot provide the stated inward focus travel.
- Filter diameter:1.25 inches
- Positions:5
- Included filters:Luminance, red, green, blue
- Material:Aluminum
- Focus travel:Requires an additional 20 mm
- Operation:Manual filter switching described; motorization not specified
- Intended use:Astrophotography
Our verdict“I rank it first for a compact mono-camera starter system because it pairs a five-position wheel with LRGB filters, provided the 1.25-inch format and focus requirement fit.”
SVBONY SV133 2-Inch Filter Wheel Telescope Accessories
For an imaging setup already built around larger accessories, the SVBONY SV133’s 2-inch compatibility is its main distinction. It has five positions, an aluminum housing, and a light-tight interior described as reflection-free. Those details make it the format-led alternative to the Astromania 1.25-inch bundle: the SV133 can suit a 2-inch path, but it does not arrive with the listed LRGB set, so the buyer must choose filters separately.
The description also names compatibility with 2-inch eyepieces, DSLR and CCD cameras, plus multiple adapters. That breadth is useful, though a mono-camera owner should verify the exact thread and spacing required rather than assume every connection is included. Setup may be more involved than the simpler bundled Astromania option, and five positions still mean a manual wheel rather than an automated carousel; motorization is not listed. I place it below the all-in-one pick because it solves the format problem, not the filter-selection problem.
Pros:- Supports five filter positions in a 2-inch format.
- Aluminum housing with a light-tight interior described as reflection-free.
- Listed adapters and compatibility cover several camera and eyepiece types.
Cons:- No LRGB filters are listed as included, so the set must be assembled separately.
- The exact camera threads and adapter configuration should be checked before ordering.
- Setup may be more involved than the compact Astromania 1.25-inch wheel.
Best for: Mono-camera imagers whose optical train uses 2-inch accessories and who want a five-position wheel with a light-tight interior.
Not ideal for: Buyers seeking an included LRGB filter set, a compact 1.25-inch setup, or confirmed motorized control.
- Model:SV133 / FAUW9103B
- Filter positions:5
- Format:2-inch accessories
- Material:Aluminum
- Listed compatibility:2-inch eyepieces, DSLR, CCD cameras
- Weight:1.9 pounds
- Warranty:1 year
Our verdict“I recommend the SV133 when 2-inch compatibility and a light-tight interior matter more than having filters included in the box.”
Alstar 2-Inch Deluxe Telescope LRGB Filter Set
The Alstar set is the straightforward choice for a mono-camera imager who already owns a 2-inch wheel and needs the four core channels: luminance, red, green, and blue. Its value within this lineup is the 2-inch filter format and the stated CNC-machined metal cells with anti-reflection treatment. Unlike the SVBONY wheel, it supplies filters rather than a mechanism for changing them; unlike the Astromania bundle, it does not combine the wheel and LRGB set.
That separation is a benefit only if the rest of the system is ready. Without a wheel, changing filters by hand interrupts a sequence and adds handling, so I would not treat this as a complete imaging solution for someone starting from scratch. The description says the filters fit 2-inch telescope accessories, but buyers should confirm cell dimensions and wheel compatibility before purchase. Compared with the 1.25-inch Astromania bundle, this set favors larger-format equipment and an existing investment over convenience in one package.
Pros:- Includes the four core LRGB channels for monochrome imaging.
- 2-inch format suits compatible larger accessories.
- Metal cells and anti-reflection treatment are specified.
Cons:- A filter wheel is required for convenient filter changes and is not included.
- The 2-inch format can be a poor fit for an existing 1.25-inch system.
- Compatibility with a specific wheel should be checked before purchase.
Best for: Mono-camera users with a compatible 2-inch filter wheel who need a matched LRGB set.
Not ideal for: Beginners without a wheel, owners of a 1.25-inch optical train, or buyers seeking a complete ready-to-switch package.
- Filters included:Luminance, red, green, blue
- Filter size:2 inches
- Filter material:Dichroic glass
- Cell material:CNC-machined metal
- Finish:Black anodized
- Coating detail:Anti-reflection treatment
- Wheel included:No
Our verdict“I’d choose the Alstar set to complete a compatible 2-inch wheel, but the Astromania bundle is the more complete starting point for a new LRGB rig.”
Astromania 1.25-inch Filter Wheel for Telescope – 5 Position with T-Adapter & Eyepiece Adapter
This Astromania wheel is aimed at buyers who want one manual unit for both eyepiece use and camera work. The package lists a T2 camera adapter and eyepiece adapter, plus a reference system for filter placement and a storage case. That makes it more versatile on paper than the LRGB bundle, which focuses on supplying color filters, but this model does not list any filters. A mono-camera owner still has to source an appropriately sized set.
Its clearest drawback is the 23 mm inward focus requirement, three millimeters more than the other Astromania wheel listing. That difference can matter when a telescope has limited back focus. Compared with the SVBONY SV133, this wheel is for 1.25-inch filters and includes named camera and eyepiece adapters; compared with the first-place Astromania, it offers adapter flexibility but not the included LRGB set. I’d rank it for mixed use, not as the easiest route to a mono-camera color workflow.
Pros:- Five positions allow several filters to stay mounted for quick manual selection.
- Includes T2 camera and eyepiece adapters, plus a storage case.
- Reference system helps identify filter placement.
Cons:- Requires 23 mm of inward focus travel.
- No filters are listed as included, unlike the other Astromania bundle.
- Motorized operation is not specified.
Best for: Buyers who switch between visual observing and camera use and want a 1.25-inch wheel with listed adapters.
Not ideal for: Mono-camera beginners who need filters included, or telescope owners with limited inward focus travel.
- Brand and model:Astromania SKU_AM_FW1M5
- Positions:5
- Filter format:1.25 inches
- Listed adapters:T2 camera and eyepiece
- Focus travel:Requires 23 mm inward travel
- Weight:13.37 ounces
- Included storage:Case
- Filter set:Not listed
Our verdict“I’d pick this over the LRGB bundle for its listed visual and camera adapters, but choose the bundled Astromania model if included filters are the priority.”
Cokin Square Filter Traveller Creative Kit – Includes M (P) Series Filter Holder, Circular Polarizer, ND8 3-Stop, ND4 2-Stop Hard Filters, and Filter Wallet
This Cokin kit is the outlier, and the distinction matters: it is a landscape photography filter kit with a P-Series holder, circular polarizer, and graduated neutral-density filters. Those tools control exposure, reflections, and sky-to-ground balance in conventional photographic scenes. They do not provide the luminance and RGB filter sequence or astronomy filter wheel described by the other four products, so I would not recommend it as a mono-camera imaging set.
Its compact wallet and starter assortment could suit a photographer using compatible P-Series gear, but that is a separate job from capturing LRGB frames through a telescope. Compared with the Alstar set, it has neither astronomy-focused LRGB filters nor a 2-inch accessory format; compared with the wheel products, it has no multi-position mechanism. I include it to make the category boundary explicit: a product labeled as a filter kit can be useful and still be the wrong tool for this buying guide’s purpose.
Pros:- Includes a holder, circular polarizer, graduated ND filters, and a wallet.
- Portable kit supports landscape exposure and reflection control.
- Provides several creative filters in one package.
Cons:- Designed for landscape photography rather than mono-camera LRGB imaging.
- Adapter rings are sold separately and it is limited to P-Series filters.
- No astronomy filter wheel or LRGB set is listed.
Best for: Landscape photographers using compatible Cokin P-Series gear who want graduated ND and polarizing filters.
Not ideal for: Anyone shopping specifically for a filter wheel or LRGB filters for a monochrome astronomy camera.
- Brand and model:Cokin Traveller Creative Kit
- Holder:P-Series filter holder
- Included filters:Circular polarizer, ND8 3-stop, ND4 2-stop hard graduated ND
- Filter system:Cokin P-Series
- Weight:0.34 kg
- Included storage:Semi-hard filter wallet
- Warranty:1 year
- Intended use:Landscape photography
Our verdict“I would skip this for a mono-camera system; its role is landscape photography, not astronomical filter sequencing.”
How We Picked
I ranked these options by how directly they serve mono-camera imaging: filter format, number of wheel positions, included LRGB filters, connection details, and stated focus requirements. A bundle with a wheel and color filters can get a buyer started with fewer separate decisions, while a standalone filter set makes more sense when the wheel is already in hand. I also weighed details that affect setup fit, including 1.25-inch versus 2-inch compatibility and included adapters.
The product descriptions leave gaps, so I treat them as gaps rather than assume a feature is present. Neither Astromania listing specifies motorization, and the supplied information does not confirm that the SVBONY wheel includes a particular mono-camera thread or every adapter a buyer might need. The Cokin kit is included as a clear boundary case: it contains photographic filters and a holder for landscape work, rather than an astronomy filter wheel or LRGB set. My order favors usefulness for the stated topic, then distinguishes options by format and completeness.
Factors to Consider When Choosing Filter Wheels And Filter Sets For Mono Cameras
I’d choose the filter format and switching method before comparing individual bundles. For a mono camera, the filters, wheel, telescope focus, and camera connection need to work together; a good standalone set can still be the wrong purchase if it cannot fit your existing wheel.
Match the filter size to the optical train
1.25-inch and 2-inch filters are not interchangeable by assumption. The Astromania LRGB bundle is built around 1.25-inch filters, while the SVBONY SV133 and Alstar set are aimed at 2-inch accessories. Check the wheel opening, adapters, and any other components in the light path. A smaller format can suit a compact system, while a larger format keeps the set aligned with an existing 2-inch train. Avoid choosing by camera body alone; the telescope-side fittings and spacing matter too.
Decide whether you need a wheel, filters, or both
A filter wheel keeps several filters mounted and lets you change channels without removing each filter from the imaging train. A set such as Alstar’s supplies the LRGB filters but no wheel, so it is best for someone who already has a compatible mechanism. The first Astromania option bundles both. The adapter-equipped Astromania wheel provides connections but no listed filter set, while the SVBONY wheel also requires separately sourced filters. For a new mono-camera setup, accounting for both pieces avoids buying only half the workflow.
Check focus travel and camera connections
Focus travel can decide whether a wheel works with a telescope. The two Astromania listings specify 20 mm and 23 mm of additional or inward travel, respectively. Compare that requirement with the available focuser range using the intended camera and adapters. Also verify thread type, adapter depth, and spacing. The SVBONY description lists broad camera compatibility and adapters, but the exact connection for a given mono camera is not detailed. Confirm the required parts before treating a general compatibility statement as a guaranteed fit.
Choose manual switching with realistic expectations
Each wheel description here supports quick manual filter changes, but none specifies motorized control. If you plan automated imaging sequences, check whether the wheel itself supports control or whether you’ll need a separate system. Manual switching is simpler for visual use or occasional channel changes; it requires you to operate the wheel yourself during a session. A five-position wheel offers room for LRGB plus another filter, but the listings do not establish that every wheel uses the same slot arrangement or connection standard.
Keep photographic filter kits in their lane
The Cokin Traveller set illustrates why the intended use matters. Its circular polarizer and graduated neutral-density filters are described for landscape photography, and the kit uses a P-Series holder. Those features do not make it an astronomy LRGB set. When shopping for monochrome-camera imaging, look for the needed filter bands and a compatible astronomy wheel or cells. If your goal is conventional outdoor photography, Cokin may make sense; for the setup covered here, the astronomy-specific products are the relevant choices.
Frequently Asked Questions
Which product is the most complete starting point for mono-camera LRGB imaging?
The Astromania 1.25-inch five-position wheel with LRGB filters is the most complete single package in this group because it lists both a manual wheel and luminance, red, green, and blue filters. It still needs to fit your system: confirm that your accessories take 1.25-inch filters and that your telescope can provide the stated additional 20 mm of focus travel.
Should I choose 1.25-inch or 2-inch filters?
Choose the size that matches the wheel and optical train already in your setup. The two Astromania wheels are listed for 1.25-inch filters, while the SVBONY wheel and Alstar set are associated with 2-inch accessories. Check the filter cells, wheel opening, adapters, and camera spacing together; a filter set in the wrong format may require other components and may not fit your existing equipment.
Do the listed filter wheels change filters automatically?
The supplied descriptions identify manual filter switching and do not specify motorized or computer-controlled operation for either Astromania wheel or the SVBONY SV133. If your imaging plan calls for automated sequences, confirm the wheel’s control method and compatibility with your software before buying. The presence of multiple positions alone does not establish automation.
Can I use the Alstar LRGB filters without a filter wheel?
The Alstar set contains four filters but does not include a wheel. You can use the filters only if your imaging setup has a compatible way to mount and change them; a wheel is the convenient route for switching channels while keeping filters installed. Check that the 2-inch cells match your wheel and accessories before pairing them.
Is the Cokin Traveller kit suitable for a monochrome astronomy camera?
It is not presented as an astronomy filter set. The Cokin kit contains a P-Series holder, circular polarizer, and graduated neutral-density filters for landscape photography, with no LRGB set or astronomy filter wheel listed. For mono-camera color imaging, choose an astronomy-specific wheel and filters that match your system’s size and connections.
Conclusion
For a new 1.25-inch mono-camera setup, I’d start with the Astromania wheel bundled with LRGB filters, after checking focus travel. If your imaging train is already built around 2-inch accessories, the SVBONY SV133 is the wheel pick and the Alstar set is the filter pick for owners who already have a compatible wheel. Choose the adapter-equipped Astromania wheel for mixed eyepiece and camera use when its 23 mm focus requirement works for your telescope. I’d leave the Cokin kit to landscape photographers; it does not serve the LRGB imaging job covered here.
