This is about my favourite mineral moon, taken Feb 26th this year. The colours have come through just enough Click through for the full size (2910x2919)

Beautiful crescent moon in the fading daylight, yesterday evening

Thank you!

Daystar Quark Chromosphere / 80ED / 174m Surface and prom composite from 2 stacks. 5ms low gain for the surface and 10ms high gain for the prom. False coloured in PS 1 hour of data, 1000 frame once a minute. Sharpened in Pix and aligned with Dave’s Video Stabiliser

Thank you! It was today, yes. A little hazy, but clear enough. Around 40 minutes from 12:15 to 12:54pm

The rest of the data from here : https://stargazerslounge.com/topic/374801-prominence-3003-quark-80ed/ imPPG wouldn't align these, so this was 36 frames aligned by eye in PS

A little bit of sunshine means a little bit of sun! A large prominence raining plasma onto the surface of the sun SW80ED + Quark chromosphere / Hypercam174m. Composite of 2 stacks, one for the surface and one for the prom edit: Animation here: https://stargazerslounge.com/topic/374817-animated-plasma-rain-3003-quark-80ed/

Happy to help out 👍🏻

Thank you!

Tonight's first quarter moon. RGB combine of 500 frame stacks from 2000 in each channel. Saturation lifted a little After such a cloudy day, I was quite surprised the data came in so clean. This is what AS!3 thought it:

After thin cloud spoilt my grab for a daytime moon, I had thought the day was a bust - until the un-forecast clear early evening! My view west is basically my house, so it was a very limited session, racing against the moon's inexorable slide into my ridge tiles. I only managed 1 pass of 1000 frames each LRG and B before the straight line of doom started marching across my screen

I'd have a play with HLVG, otherwise you skip inverting it and tune it with the colour channels or defringe in Camera Raw Filter

I'm using PIxInsight and PS, depending on what I'm doing. In PS it's Image -> Adjustments - Invert (CRTL+I) If you're treating the fringing in PS, then you can use Camera Raw to reduce it (Filters -> Camera Raw Filter. Then look for the Optics, Defringe) That's in the latest version, but it's been in for a while

I downloaded your tif data and had a play. -Inverted and removed green, then inverted back (effectively removes magenta) -Boosted the exposure and the saturation, slightly -Selectively dropped the saturation on the orange / yellow crater highlights and similar with the blue - these where most visible is the bottom left crater fields

Happy to help, Bryan! I'm looking forward to seeing the final image!

Humm, so I took the data from my last 49 panel mosaic (full version here) and threw it at Photoshop... Photoshop: Microsoft ICE: I freely admit to never having tried this in PS before now, so I might be missing the ways to finesse it

Thanks! I’ll try that later too, and we can compare our experiences 👍🏻

I have ICE backed up Google Drive link It does a good job - and I’ll be trying Photoshops tool, as I’ve never tried that

Hello Bryan! Wow, that looks like some cracking data! My process would be to stack as you have, then use Microsoft ICE to mosaic the images. From there imPPG should align them so you can combine it

Very nice! Well done Steve!

I usually do something like this: Stack in AS!3 giving 2 x Red, Green and Blue panels (asi178mm + 80ED can't quite do the full disk in 1 hit) Registax Waveletts all 6, with the same settings. Not going to 'crunchy' Stitch the frames in Microsoft ICE and save out the 3 mosaic channels Align those 3 in imPPG Open in PixInsight and convert them back to greyscale LinearFit the Red and Blue to the Green LGRB combine - This should give a reasonable colour balance without a distinct cast Curves Adjustment on Saturation to bring the orange and blue up out of the grey. At this point, I'm able to spot the fringes clearly: SCNR noise reduction with it's default settings to remove green Invert the image and run SCNR noise reduction again, effectively removing magenta (inverted green) Invert back, then off to Photoshop for polishing in Camera Raw

Thanks Neil. The ED puts the colours together quite well, but there has been some worth removing some fine green and magenta fringes.

My allsky managed to (just about) catch last nights meteor - Right side of the image, capture time was 21:54:29, Lancashire. South to the right, E to the bottom 11 sec exposure

Lovely images! Thank you for sharing and the write up.
