QHY offers a very comprehensive and flexible adapter system that allows our cameras to achieve focus with a variety of accessories, including camera lens adapters, off-axis guiders, filter wheels and numerous optical systems.  Based on users’ feedback, we provide fixed combination of adapter kits to meet mainstream needs of most users (e.g., Multi-Purpose Coma Corrector, Canon lens adapter, Nikon lens adapter, etc.). Users can choose the corresponding adapter set according to their needs to ensure focus. There is no need to measure and calculate the back focal length, choose adapters, and customize screws.

Back Focal Length Defined

Back Focal Length (BFL), in the commercial camera field, refers to the design distance from the center of the rear lens element to the surface of the sensor.  Generally, the lens will only focus correctly at infinity if the camera’s back focal length meets the standard requirements provided by the lens manufacturer.  This is also true for many Multi-Purpose Coma Correctors designed to be used on telescopes before the camera.

Optical system Back focal length required
Typical Multi-Purpose Coma Corrector 55mm – 57.5mm
Canon 35mm lens 44.1mm
Nikon 35mm lens 46.5mm

 

Note: Not all astrophotography gears have specific BFL requests, for example, some refractor scopes with internal flat correctors. In such cases, you needn’t use the following adapter kits. Instead, you can use a T ring or any adapter that can help connect your camera and scope.

"Back Focus Consumed" Defined

When an optical system requires the sensor of the camera to be located at a specific distance from the last optical element, mechanical spacer adapters are used to position the camera at the right location. If the camera system also includes a filter wheel and an OAG, for example, between the camera and the telescope, the space required for these items must be taken into account. As a simplified explanation, for example, if a telescope’s field flattener requires the camera focal plane to be 55mm behind the last optical element, and the filter wheel is 20mm thick, and the OAG is 10mm thick and the sensor is set 10mm inside the camera then these items all take up 20+10+10=40mm of the back focal distance. Still, the camera needs to be 55mm away so we need to add spacers that take up this remaining 15mm. This also means that if you have an optical system that requires 55mm of backfocus distance and your filter wheel is 25mm thick and the OAG is 20mm thick and the sensor in the camera is 17mm from the front plate, then these items take up 25+20+17=62mm of backfocus. Too much! In this case something has to go to reduce the total back focus distance of the camera to 55mm or a different optical configuration must be found.

For the convenience of calculation, all the data displayed are the increase in the back focal length taken up by using the adapter, which is not necessarily equal to the thickness of the component itself.  All the adapter data provided by QHYCCD are based on the focal length increment.

Recommend Combinations

At present, our adapter combinations for monochrome cameras are based on the focal length of the following combinations, which are also our recommended combinations. If you use combinations other than those recommended, the adapter set may not achieve its purpose.

Adapter Kits Introduction

Note: in 55mm solutions,  if you do not want to use an OAG in the above combinations, we provide an additional 10mm spacer adapter in some kits to replace it.

A1-A3 (for 163M, 294M)


A1

QHYCCD Astronomy Camera Adapter SolutionA1: Connecting MPCC that requires 55mm BFL and M48 interface to Camera with Filter Wheel and OAG.

QHYCCD Astronomy Camera QHY294 Combos

Note:

  1. If you only own CFW3M-SR whose BFL is 20.5mm rather than 17.5mm, this adapter combination can still be used, just remove the 3mm and 0.5mm adapters.
  2. If your MPCC requires a BFL different from 55mm, this adjustment can be made by selecting the appropriate spacer between the MPCC and the OAG.  For example, an MPCC that requires 57.5mm can be used instead by adding a spacer ring or rings that add 2.5mm of BFL. to the diagram above.
  3. If you don’t use an OAG, you can use a 10mm spacer adapter in the adapter kits to replace the original position of OAG.
  4. Put OAG at the position next to the M48 Output to make both main cam and guiding cam focused.

A2

QHYCCD Astronomy Camera Adapter SolutionA2: Connect Canon lens with filter Wheel. You need to remove the filter wheel and the original connection interface of the camera and replace it with a new adapter.

A3

QHYCCD Astronomy Camera Adapter SolutionA3: Connect Nikon F Lens to Camera with Filter Wheel

QHYCCD Astronomy Camera QHY294 Combos

B1-B3 (for 268M, 600SBFL)

B1

B1: Connecting MPCC that requires 55mm BFL and M48 interface to Camera with CFWL and OAG. B1 is standard accessories of QHY600M SBFL and QHY268M, so you needn’t purchase it if you’ve had the cams. If you own a CFW3M-US (which is 17.5mm) rather than CFW3L (21.5mm),  you need to add another 4mm adapter and longer screws, which are also included in B1.  Below shows two examples:

Note:

  1. If your MPCC requires a BFL different from 55mm, this adjustment can be made by selecting the appropriate spacer between the MPCC and the OAG.  For example, an MPCC that requires 57.5mm can be used instead by adding a spacer ring or rings that add 2.5mm of BFL. to the diagram above.
  2. If you don’t use an OAG, you can use a 10mm spacer adapter in the adapter kits to replace the original position of OAG.
  3. Put OAG at the position next to the M48 Output to make both main cam and guiding cam focused.

 

B2

B2: Connect Canon EF lens to Camera with filter wheel

B3

B3: Connect Nikon F Lens to Camera with Filter Wheel.

Note: The current Nikon adapter used here is different from the 10mm adapter we used to provide. Now it has a back focal length increment of 12mm.

 

 

B4 for New 268C

From 2023, the top part of QHY268C will change to the shorter one just like that of 268M. In fact, you can get the “SBFL(shorter back focal length” version of 268C right now.

The previous 268c has a back focal length of 17.5mm, and since it cannot connect to the scope without CAA, so it’s actual BFL is 17.5mm+6mm=23.5mm. Now after the change, 268C’s BFL will be shorten to 14.5mm, which provides more spaces for a filter wheel drawer, or an electric CAA, or DSLR Lens, etc.

The new 268C adapts a new kit B4 which can best make use of the standard accessories. B4-2 and B4-3 share common parts from the necessary B4-1(for MPCC) .When you need to connect Canon or Nikon lens, you only need to get one Canon/Nikon adapter, not a “kit” like D2 or D3 anymore.

C1 (for 600M-PH, 600L)



Kit C1 is for connecting MPCC that requires 55mm BFL and M48 interface to Camera with CFW3L Only. C1 is standard accessories of QHY600M PH and QHY600L, so you needn’t purchase it.

Note: The combo QHY600M-PH+CFW3L+OAG combo are not compatible for MPCC because of limited BFL. If you need an MPCC while using the CFWL and OAG at the same time, or use DSLR Lens, we recommend you choose QHY600 SBFL version.

D1-D3 (For OSC cams with APS-C and Full Frame Sensor)


Combos and Adapter Kits

Generally speaking, there’s no need for an OSC (one shot colored) camera to match filter wheel. If there’s any special needs, please refer to mono cam combos and choose the corresponding filter wheel. All OSC cams use OAG M if needed.

Model BFL Consumed
QHY600C/410C/367C/128C/247C/168C 17.5mm+6mm (CAA)
QHY268C (Version before 2022) 17.5mm+6mm (CAA)
OAGM 10mm

 

*About IR-Cut filter

The sealing glass of QHY OSC cameras whose format are above APS-C is AR glass instead of IR/Cut filter. That’s because when the sensor size is bigger, if IR/Cut is closed to sensor, it’s easy to cause haloing effect on image. We use IR/Cut filter as sealing glass on 4/3 format cameras or below, like 163C, 183C; as for big sensor OSC cams, such as 268C, 367C, we provide a special adapter for fixing 2-inch IR/Cut filter at a farther position from the sensor, or users can fix the filter inside the default T mount.

D1

D1: Connecting MPCC with 55mm BFL and M48 interface

If you don’t use an OAG, please use 10mm adapter in the adapter kits to fill the original position of OAG.

D2

D2: Connecting Canon EF Lens


D3

Connecting Nikon F Lens

E1 (for 533C, 294C, 174C)

Adapter Kit E1 can be directly connected to the 55mm BFL M48 interface MPCC, or Nikon / Canon DSLR lens (need to purchase another DSLR lens adapter). 

E1 is designed for QHY533C, 294C, 163C, 183C, 174C. Of course, if you use 163M/294M/183M/174M while a filter wheel or OAG is not needed, you can use E1 as well.

 

F1 (for 533M)

QHY533M external use of threaded interface can be directly connected to the small filter wheel. This time we will launch a special standard small filter wheel version together with the 533M, which can be assembled directly by the user externally without removing the disc. When the QHY533M + filter wheel combination is connected to a DSLR lens, only an additional DSLR lens adapter ring (sold separately) is required to complete the focus. 

M54 All-in-one Adapter Kit

If all the existing package solutions cannot meet the demand, such as the situation where the BFL requirement is very special, we also offer this all-in-one accessory package which includes almost all kinds of M54 adapters we have.

The many potential combinations of these items produce an equal variety of back-focus distances that must be considered to make it all work together.  This variety and flexibility can let you get any BFL you want through this kit.

M42 All-in-one Adapter Pack for QHY183M

Currently We only provide M42 All-in-one pack for QHY183M. Different from kits above, all adapters/spacers in this pack share M42 screws rather than M54. This kit ONLY suits the combo of QHY183M+CFW3S-US/CFW3S-SR+OAGS. Below lists some examples of using the kit (M42 Nikon/Canon adapter not included in this pack)

Note: this kit also suits other cameras with sensors one inch or smaller (e.g., QHY183/178/174/290).
