QHY8 and QHY8Pro Reflections
Both these cameras seem to suffer from reflection problems between the front IR filter and the CCD. There has been quite a bit of discussion here in Australia about this problem and fixes for the use of things like MPCC etc. I personally don't use a MPCC imaging with a FSQ106 but have managed to rectify the problem I have by removing the front IR filter and adding it to the front of the camera adapter, some 2" in front of the CCD. The results speak for themselves. I have attached 2 images taken on two consecutive nights.
The first image is taken with the stock IR filter on the QHY8Pro and the second with a Baader IR filter fitted to the front of the camera adapter with the stock filter removed.
Bothe images are 6 X 10 minute exposures stacked in IP3 and finished off in CS3. No calibration files used for these images.
Anyone have any better ideas?
