Thank you - Brilliant images. Shows what I've missed while my rig is in pieces and the cloud dominates!

Doesn't mean I know what I'm doing, though!

Great images. I thought you'd like to see a short time-lapse I took of what I think is the same object on the 4th. I take single Ha frames every 15s for as long as I'm able, then stitch them together as a video, with some final garbage removal and image tweeking and cropping. I use a Coronado PST for Ha, piggy backed on a Skywatcher Evostar 80ED DS-Pro with a Baader solar filter for white light images, the mount is a SkyWatcher NEQ6-Pro.

For capture I use SharpCap with drift compensation using the SharpCap 'Feature Tracking' Tool.
For processing I use PiPP, and VirtualDub.

Cairomike, Pedro , Alexandra many thanks for your comments :)

Cairomike great vidéo of this huge proms :) in the past, I made animations with the 230 mm H-Alpha Refractor, but it is very difficult to have a good seeing with this diameter over a long period of time !!!
