Description

Working with my portable set-up and getting familiar with it again after changing from the Canon EOS Ra to an ASI2600MM and filter wheel I gathered data on M4 last night.
I could have framed the area better to get more detail but I'm very happy with the result. Borg 55FL @ f3.6 & 205mm FL, ASI2600MM, ASI EFW 7 position filter wheel, ASI Air Plus, RST-135 mount.
2 hours and 56 minutes of RGB data.
