Description

This is first light night with my edge hd 800. I could not get my guiding to work like it should. I have been able to do 10 min subs with my 80mm with a short focal length, but this 8" SCT provided a nice challenge for the guiding. I was not able to solve my issues yet, but i will keep at it. any advice would be greatly appreciated for setting PHD with a longer focal length OTA. Thanks for looking!
