QHYCCD Adapter Kit A1 for MPCC

A1: Connecting MPCC that requires 55mm BFL and M48 interface to Camera with Filter Wheel and OAG.

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: 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: Connect Nikon F Lens to Camera with Filter Wheel

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:

B2: Connect Canon EF lens to Camera with filter wheel

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.

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 eletric 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.

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.

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.

*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: 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: Connecting Canon EF Lens

Connecting Nikon F Lens

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.

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.
