With orion season coming up, I'm looking to get in to widefield narrowband imaging with my AZ GTe mount. Currently I have the set up purring like a kitten, however, my main issue is with the EOS adapter. It's producing weird pinched stars of sorts that aren't consistent through out the image. I'm having a quick guess it's due to tilt. I'm using the recommended spacing that ZWO has for their EOS efw adapters (i.e. no spacers just the efw and camera) so not sure if the spacing needs fine tweaking or not. I'm actually just going to replace the cheap adapter with something more solid. If anyone has any recommendations, I'm all ears.
Astrobin link here for those that want to inspect stars (please do)
I know a lot of you are *sick* of starless renditions but cmon you gotta admit this one looks good
