ASI094MC Pro Halos/Disks/Rings

Postby whutton » Fri Feb 09, 2018 11:55 pm

I recently purchased this camera to add to my collection of ZWO cameras. I've done some very short duration and with just enough frames to stack and do some very initial processing. The following image was taken a Takahashi FSQ130-ED, the 094 fitted with a IDAS LPS D1 light pollution filter.

I was surprised at the sharp halos around not just Alnitak but other bright stars also. I've not seen this before with my ASI071MC Cooled. I've see this in other images by other AP imagers using a different filter.

Any idea as to what would be causing this?

Sorry if this shows up multiple times, but it doesn't seem to be reaching the forum.

actually 094 is an AR coated sensor and should be better than 071 in these aspects
and the back focus distance for 094 and 071 is the same
so I don't under stand there is such difference

maybe you can test again with 071 and 094 side by side
