Nikon D850
Tamron 150-600mm @ 600mm in DX mode = 850mm
SkyGuider Pro - tracking
41 x 120secs at ISO 800
No Dark, Flat or Bias used since I did it all in Photoshop. I could have used Darks, but at ISO 800 I didn't have any noise issues.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
