very timely to find this challenge, got to have my second outing with the quark this weekend and boy was it fun! still slowly picking up the processing skills and the seeing wasn't great, but solar imaging is just awesome. really handy as our nights are almost always clouded but days can often have moments of clear sky

Bresser 127L/1200 doublet, Quark Chromosphere, Astronomik UV/IR L-3 (as ERF), PlayerOne Apollo-M Max, Skywatcher EQ6.

Each shot stacked 10% best of 1500 frames. Captured Sat 27th May 2022 10am-12pm NZT

Workflow: AS3->IMPPG-> PixInsight ->Photoshop

used earth for scale in one of them, credit to nasa for earth photo. these are all inverted. the highly vignetted one is when i used 0.5x reducer, too much vignetting but did have a nice improved FOV, so decided to share anyway.

Had another weekend of some clear skies. Just a brief moment 30mins with not great seeing but got surprisingly decent details in. It is just my 3rd session out with the quark so still working on fine tuning things, but having an amazing time with solar. attempted a mosaic too but only got to 17 panels before clouds rolled in hence it's looking quite in complete.

Today the seeing was above average, and I managed to sneak my phone up to my 18mm Baader Classic Ortho eyepiece, in the back of my 102mm Tecnosky F7 apo and Daystar Quark Chromosphere. The image was shot in "Pro" mode with my Oneplus 7 Pro, and later edited in Photoshop Express on my phone. Capture details are 1/250s exposure and ISO 320.

And another one slightly more centered on the solar disk instead of the limb.

Lastly, the north eastern limb with two small proms!

Hello everybody!
I don't have a setup dedicated to solar photography, so for fun I usually use a Baader solar sheet and a Solar Contnuum filter with the C14 or an Explore Scientific AR 127. Below are some contributions to the post.

This image was captured in Hydrogen alpha on the 16th June 2022 and shows a large prominence on the eastern limb.

A 1,000 frame video was stacked in AS3! using 11% of the best frames. It was then taken into ImPPG and an initial sharpening was applied and the tone curve adjusted to invert the image. Finally it was brought into Affinity Photo where further sharpening was applied using ‘Clarity’ and ‘Unsharp Mask’ and a slight adjustment was made using curves.

Equipment

  • Lunt 60mm Double Stacked THa B1200/CPT
  • ZWO ASI174mm with tilt adapter
  • SkyWatcher EQ6R-Pro mount.
  • TeleVue 4x Powermate.

Second image (below) captured 28th June 2022. Same equipment used as above, however this time I captured an overexposed solar disc to reveal the prominences then set the gain to 230 and exposure to 9.8 ms to capture the Chromosphere. These two images were processed individually in PixInsight then the two were taken into Affinity Photo where I copied the surface on to the prom layer, adjusted to match the limbs and applied the ‘difference’ layer.

Final image. Captured 28th June 2022 quite early in the morning at 06:10:48 UTC as the forecast was for clouds to roll in (which they did). Using the Lunt described above and ZWO ASI174mm, I captured 2,000 frames and then stacked 10% in AS3!. I took the resulting image into ImPPG and sharpened this a tad before manipulating the tone curve tool to invert the image and lighten the background. Then into PixInsight. A DynamicBackgroundExtraction was undertaken to the sky area. I then created a range mask to encompass the solar disc. The mask was applied and Unsharp mask applied at 10 pixel scale to pop out the filaments. The mask was inverted so exposing the prominences and I used the RestorationFilter tool to apply a bit of sharpening to the proms.

After temporarily removing the mask, I converted the image to RGB, re-applied the mask to expose the disc then applied colour using the curves tool. A final tweak of curves to lighten the limb and darken the centre was added before I Resampled the image reducing its size to 1024 pixels across its width whilst maintaining the same aspect, then created the border and annotated the image with its details.

On 23 June 2022 @ 08:14UTC a large prominence was visible on the Sun's eastern limb.
