Description

A sunny morning to begin the May Bank Holiday....and above average seeing in the mid-morning.  Used the 94mm f/7 refractor with a 2.25x Baader Barlow lens to take 6 panels each for the full discs in WL (with Baader Herschel wedge), CaK (Lunt B1800 CaK module) and Ha (double-stacked Coronado SM60).

Exposures ranged from 0.46ms (CaK) to 1.19ms (WL) to  2.5ms (Ha).   Average frame rate was 130fps.

3000 frames per panel with 225 selected.  Aligned and stacked in AstroSurface.  Full disc assembled in PS6; further RL deconvolution and wavelets in AS (Ha in ImPPG) and then final touches in PS6.
