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

Happy to help out 👍🏻

I have ICE archived : Google Drive link - MS ICE

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

how do you remove green

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

when you say invert, are you using photoshop

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...

Microsoft ICE:

I freely admit to never having tried this in PS before now, so I might be missing the ways to finesse it

photomerge option

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!

Well your Fine tuning has worked well

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.

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

and a not so crazy version with the 80ED, in RGB

I spend a pleasant evening on Saturday on a skype call, sharing the moon through my C8 / asi178mm and ended up taking a mosaic, because 'why not?'.

49 panels later, and we have this monster! Click through for the full view

That's no moon! That's a...oh, it's a "snow moon" 😀

Surface / Planetary is how it stabilises the image. You want surface, and ctrl + click the green box so it covers a high contrast feature - the edge works well.

Not getting any APs : This might be the minimum brightness setting, just above the Place AP grid button. Try lowering it to 10. You want the APs covering the lit areas. Dark low contrast features can confuse it - tune the brightness option until you get a good spread

Nicely balanced.

Thank you!

The almost full moon from the 25th

This is a 2 panel mosaic in RGB with the asi178mm.
It almost wasn’t colour, as the blue data was being a pain and had a noticeable band when merged. A careful restock and reprocess sorted it out

Hope everyone has a lovely weekend! Clear skies
