Close up of AR2741 in Ha, time-lapse image 16 May 2019

[Hughsie]

This is made up of 24 AVI's of a 1,000 frames each. Each AVI was processed in AutoStakkert2 using 50% of the frames to create 24 individual TIF files. Flat frame also generated from a  50% stack of 1,000 frames and used to calibrate each AVI stack. Imaging started at 09:56 BST and continued at 4 minute intervals until the 24th run was made at 11:28 BST. 

Camera Settings; Exposure 10ms; Gain 40

Equipment - William Optics Z103, ZWO ASI174MM and a Daystar Quark Chromosphere.

Software - SharpCap for image capture, AutoStakkert2 and Photoshop (Levels adjustment applied then two runs with the Unsharp Mask 1) 300% at 1 pixel then 2) 40% at 5 pixels). The TIF layers were then aligned, cropped and ordered to produce the time-lapse with a 0.08s interval between each frame. 

Thanks for checking in.
