My favourite version of this image:
In image below, I have taken sharpening to an extreme – brings out some extra detail but at expense of making image seem unreal:
This example has worked better!
Image after application of SharpenAI (applied to above image):
Yesterday I downloaded a trial version of SharpenAI – a new sharpening stand-alone programme/plug-in for Photoshop (it comes with both) that uses AI to improve sharpening of images.
Below is my first attempt at using the software, on a solar image from 5/5/2020. It is a close-up of part of the solar disc. What do you think?
Focus point on Sky Watcher Equinox 100mm+Tele Vue 75mm extension tube:
= 74mm Quark H+Daystar interference elminator+QHY ASI174MM.
= 44mm Quark CaH+Daystar interference elminator+QHY ASI174MM.
Quark H – using my new Daystar interference eliminator – it is expensive but no intuitive and easy to use! No Newton’s Rings!
This post follows from my previous post:
Adding tilt adapter to my Daystar hydrogen Quark filter
My new Rowan Tilt Adapter has successfully removed Newtons Rings from my solar images…..and cling film (thanks for idea from contributors to Cloudy Nights form) is quite good for getting those elusive solar flat fields in FireCapture!

Proof below from picture today (very windy so poor seeing and low contrast so limited solar features visible) – this image 174 frames out of about 1000 taken over 20 seconds – no Newton’s Rings and (relatively) flat field (OK, still some work to do to get this right! Perhaps two layers of cling film…….)
Here is the cling file over the telescope:
Which image do you prefer?
Newly processed image using inverted tone curve:
Or previously processed version (tone curve NOT inverted):
At last! Today, I managed to get a photograph of sun in hydrogen alpha (Quark) showing a prominence – not the best photo but hitherto I seem to have had difficulties getting prominences to show up/
