TO EXPLORE THE UNKNOWN UNIVERSE
Telescope: Askar FRA600
Mount: iOptron CEM40
Here are the combo we recommend for the QHYCCD Astronomy Camera QHY600. Compared with purchasing them seperately, you can get a discount about 5% off for the combo.
For QHY600, the match we recommend is CFW3L and OAGM. If you have a special requirement for short back focal length, like using a Canon EF Lens (44.1mm BFL), Nikon F Lens (46.5mm), or 55mm MPCC with both CFW and OAG, we recommend the QHY600 SBFL version as the only choice.
| Model | BFL Consumed | Filters Supported |
| QHY600M PH/Lite | 17.5mm | |
| QHY600M SBFL | 12.5mm | |
| CFW3L | 21.5mm | 7*2-inch mounted/50mm unmounted |
| CFW3XL | 21.5mm | 9*2-inch mounted/50mm unmounted
or 7*50mm square unmounted |
| OAGM | 10mm | |
| OAGL | ||
| OAGL Pro | 12mm |
Since June 2023, we are adding a 5mm spacer with M54 threads into Adapter kit C1. This addition gives the user a choice of terminating the output in either M48 or M54 threads. Since C1 are standard accessories included with the camera, this addition has no affect on the price list.
Note:
Combo C1 is the solution without OAG. The QHY600M-PH or QHY600M-L with CFW3L and OAG result in a backfocus greater than 55mm. Therefore, if you must limit this BF distance to 55mm due to a corrector lens or DSLR lens, we recommend the QHY600M-PH SBFL.
If you need more than 7 x 50mm filter positions for the QHY600, you can use the CFW3XL filter wheel with 9 x 50mm filter carousel.
