Agena note: We're not sure why QHY chose to refer to corrective optics in general (field flatteners, coma correctors, reducers, etc.) with the specific term 'MPCC' in their literature and product diagrams. MPCC is a specific corrective accessory (Coma Corrector) offered by Baader Planetarium, but QHY's adapter sets can be used with any corrective accessory as long as the threads and back focus length (BFL) match. They are not meant just for use with Baader's MPCC.
About QHY's Combo Adapter Kits
QHY now offers a very comprehensive and flexible adapter system that allows their cameras to achieve focus with a variety of accessories, including camera lens adapters, off-axis guiders, filter wheels and numerous optical systems. 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, however, also can be confusing particularly for new users.
Therefore, based on users' feedback, QHY has decided to offer a 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 as before. QHY will directly provide the calculated results and corresponding adapters.
If users have no special requirements for the back focal length, you can use a standard T-Mount. If you need a specific back focal length, however, you can select one of the specific adapter sets to meet your requirements or use QHYCCD's All-In-One adapter kit to combine your own set of spacer rings to meet your particular requirements. The All-In-One kits (sold separately) include 0.5, 1, 2, 3, 7 and 14mm spacers that can be combined to make any back focus combination from 0.5mm to 27.5mm.
Please also note that the Combo kit drawings depict how the adapters and other items are organized with various products such as filter wheels or an OAG, etc., but the adapter kits include only the adapter rings and screws and do not include the other products such as OAG, Filter Wheel and/or Camera.
About QHY's Combo A1 Adapter Kit Model # Combo A1
- To connect: QHY cameras with 4/3" sensors (QHY294M/163M)
- With: Corrective optics that require 55mm BFL and M48 interface to camera with filter wheel and OAG
- Product No.: 020100
- Compatible with: QHY294M/163M and CFW3M-S (medium ultra slim filter wheel) and OAG-M (medium OAG)
- To Connect: 55mm BFL MPCC
- Kit Includes:
- 5mm M54 to M48 Adapter*1
- 3mm Spacer*1
- 0.5mm Spacer*1
- 10mm Spacer*1
- 22mm M3 Screws*8
- Notes:
- This Combo A1 is included as a standard accessory with the QHY294M
- 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.
- 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 2nd photo above.
- 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.
