I guess someone has to be the first to post.  1 April itself - felt a fool setting up given how cloudy it was but GONG was showing a lot of activity.  In the end only had enough cloudless time to get 180 images (!) but seeing must have been good b/c could easily stack the best 50% & still stay high on the quality curve in AS!3.

Software: FC --> AS!3 --> ImPPG --> GIMP

Here's my first entry, am working on a hydrogen alpha whole disc as well. This was done with a White light filter used on a 150PDS captured on 2nd April through a ASI290mm, best 40% of 5000 frames on each panel.

This is the Hydrogen Alpha disc I took just after the white light disc on the 2nd. Taken with a Daystar Solar scout  SS60-DS and ASI290mm. Best 40% of 5000 frames and panels combined in photoshop. There was lots of wispy cloud around and that made it had to match the exposures of each panels. Combined with overexposed images for the prominences.

An inverted fulldisk that I took yesterday (09 April).

Cam: Playerone Apollo M-Max

Scope: Askar FRA400

Filter: PST etalon going behind Quark Chromosphere as doublestack.

5% of 5000 frames. Mosaic of 4 tiles. Processed with MS ICE, AS3!, ImPPG and Pixinsight.750156741_solar0904colourized.thumb.jpg.877dfd07e37d03dfaaf53c5d3eb7c8ea.jpg392912368_solar0904.thumb.jpg.e3bb607bc76488303f1266dc118f7ec1.jpg

Imaged with an APM 107/700mm, Daystar Quark Chromosphere and Altair Hypercam 174m 08/04/22. 11:10am till 11:20am

Mosaic from 28 x 1000 frames. Stacked in AS!3, sharpened in Registax then aligned in Photoshop:

I first tried MS ICE for the alignment, but although it did produce a disk, it miss-aligned some a couple of edge pieces. Photoshop did basically the same, but they could then be teased into position. 

Composite then of 2 layers. 1 inverted and processed for the surface details. False coloured. 2nd layer processed for the prominences' and also false coloured.

First time participating in one of these events:grin:
The following image was captured today, on the 22nd of April, with my OnePlus 7 Pro and edited in Photoshop Express on my phone. It was captured afocally through my Skywatcher Evostar 72ED, Daystar Quark Chromosphere and Baader 18mm Classic Ortho eyepiece.

Camera settings (shot in RAW):
 - 1/125s exposure
 - 2500 ISO
 - f/1.7

I imaged sunspot groups AR2993 and AR2994 over an 8 day period to show how they change their form and structure as they move across the face of the Sun. Not as detailed and high resolution as I would like but the reality was that that I had to take any small gaps in the clouds each day with associated poor seeing and gusty wind (I'm sure you can feel the wind in some of the images!) to get 8 days worth of data. The weather here in Edinburgh rarely co-operates for so long.

Interesting to see how they change over a period of time. Data captured between 18 - 25 April 2022.

This is a white light image taken through Baader solar film on a 150pds and a ASI290mm. Mosaic of 8 frames, each the best 30% of 5000 frames. Taken forever to process as Autostakert is being a real pain at the moment! Taken on a very windy 24th April of Sunspot groups 2993-5.

A detailed view of the sun through an Intes MK67, raw sketch made at the eyepiece and cleaned up afterwards for digitlisation. 

I hope sketches are allowed?

This is an animation showing AR2994-6 in both White light and Hydrogen Alpha from the 24th of April. White light taken through a 150PDS, Hydrogen Alpha taken through Daystar solar scout. Both used ASI290mm and the best 30% of 5000 frames.

Tinkering w solar animation just to see what its like.  Caught the surge prom from yesterday's X-flare subsiding - this activity is only 8 minutes duration (footage taken every 60s).  Best viewed on loop.

Processing: Firecapture --> AS!3 (batch) --> ImPPG (batch for sharpening, then alignment) --> PIPP for turning it into a video

 

[EDIT: sorry mods I posted this in the wrong section - it was meant to be in solar imaging, it is not a competition-worthy animation😂]

Canon EOS 1000D , Tal 100RS , 1.8x Barlow (modded down from 2x to suit set-up) , Baader ND3.8imaging film , Oiii filter.

100 frames stacked from 240 caught , processed in PIPP , Autostakkert 3 , Registax 5 , GIMP.

Finally managed to achieve some high resolution detail using the C9.25. AR2999 from the 30th April, during the cooler early hours of the morning.

120s  second SER file, stacked using Autostakkert, sharpened using IMPPG, coloured in CS2

C9.25, homemade Baader 3.8 film filter, asi174mm, X3 Barlow.
