Finally a clear night! After a long fall with few clear nights an opening appeared so I decided to shoot something bright. I was able to sneak in all 3 channels in one session. I thought this might be our only clear night in a while.

Started with the critical Oiii as it was a moonless night (which the signal was very strong) - Followed by Ha then sneak in as much Sii before getting treed.

These nice long nights are so rare! Clear all through until morning . Got some data on Pacman while Rosette was rising, then until dawn started on some m101 frames. Overall a great night.

I went for the wormhole look here, fun having a full nebula on the sensor! Enjoy and lets hope for a few more clear skies. Thanks for viewing!

Also and most importantly I need to thank my wife for helping me setup the mount/scope as well :)
