Very nice, one of the best full moon images I have seen.

Thank you!

any other tips ?
Choose your path first, and stick to it. A 'Z' path has less slewing, and is faster but I find I can forget which panel is next if I'm distracted for a moment. An 'E' path mean the next from is always to the right 🙂
Allow plenty of overlap, it's easy to forget the vertical and get fixated on the horizontal when doing it manually.
Make sure your exposure take in account the awfully bright areas, which can sneak up on you, 8 panels in 🙂
Try your green filter, you might find it sharper if the seeing is favourable
Never try and do this with a full RGB pass - your sanity won't survive!

"I'll be back in a minute, I'm just going to open up the observatory for later"
Bwahaha, 3 x 1000 frames shouldn't take a moment, then back inside before I'm missed 🙂
asi1600mm ROI / RGB filters. 50% stacks. Processed in AS!3, imPPG and Pi
Of course I paid for it later, when my guiding wasn't so good, and I realised I'd forgotten to reset the tracking rate. Karma bites!

pretty short integration time 👍
Under Lancashire skies, 4 hours is unprecedented, in a single session 😁

Imaged as a session ender last night - The Horsehead Nebula along with the annoyingly bright Orion's belt star, Alnitak. Also featuring the flame nebula
1 hour of 2 min subs, asi1600 / apm 107/700, Baader 7nm Ha
Had the usual massive halo around our friend Alnitak, but a bit of Photoshop seems to have rendered it presentable - microlensing artefacts I can live with

Quick and dirty M42 from last night, captured while processing some lunar data. I wasn't expecting much, and was really just a trail of the FOV.
5 min each channel of 30 second exposures, live stacked in Sharpcap. Salvaged from noise hell by Topaz DeNoise (yes, cheating!)
APM 107/700 + asi1600mm / LRGB

Crikey - that is sharp!! Well done
Thank you!

Especially when they are this good. Excellent work
Thank you! It's showing a little microlensing from the 1600, but it doesn't seem strong as it was with my previous 80ED

Last night’s moon, with @Uplooker's loaned APM 107/700. A test after transplanting my Sesto Senso 2
Of course, once I slewed to an actual target, clouds appeared out of nowhere 🤪
ZWO asi1600mm / RGB filters. 50% of 500 eachA real unlooked for joy was combining the RG and B and finding no appreciable colour fringing! Lovely optics!

do you think uplooker will be getting the scope back
Now there's a tricky question...

I've been very kindly loaned an APM 107 / 700mm (thank you @Uplooker), so after transplanting the imaging train from my Skywatcher 80ED I was desperately on the lookout for a clear evening!
30/10 wasn't awful although the relative humidity was showing 95% and stars a bit 'twinkly', it was better than solid cloud!
Setting the rig up in NINA was trouble free, once I got my head around the already installed Lakeside focuser (I've a Sesto Senso on the 80ED). Weirdly the heavier tube seemed much easier to balance on the CEM60 (guiding was a little better too)
M33 seemed a nice fit for the FOV (the scope has a x1 flattener). To have a usable dataset in the time I went for 15 x 120sec each LRG&B with asi1600mm @ -15degrees. 2hrs total, plus darks, flats & dark flats. Would have loved a run at the Ha regions, but perhaps another night. Processed in PixInsight an resampled 50%

The California Nebula: My first foray into creating a deep sky mosaic, to see how the process works. This is 2 panels each of 6 x 300sec with an Evostar 80Ed / asi1600mm x.85.
N.I.N.A. handled the framing and sequencing perfectly - the manual rotator prompts where especially helpful! The usual raft of darks, flats and flatdarks (library files, not fresh)
My first try getting PixInsight to mosaic it didn't looks so good, but good old MS Ice happily obliged to give something useable. As a practice, I think the acquisition was successful at least

A wobbly orb, capture through rather moist air last night. 25% each channel of 1000 frames RGB.
After stacking and aligning, this was combined in PixInsight and the colours balanced and gently saturated with successive curves. Slight colour fringing removed with SCNR Green / Invert / SCNR Green / Invert back

I don't think it looks drab at all.
Thank you! It's growing on on me 😆

I had intended to get some DSO work done tonight...but, yeah, weather. However, I did manage to grab a quick 1000 frames each RGB as the moon played hide and seek
I then slewed to my intended target, got clouded out, parked the scope to wait it out then had to slam the obs roof due to a sudden downpour! Wiped everything down, dehumidifier on - so got on with processing this instead
Hunter’s Moon: asi1600mm / 80ED @510mm (not ideal, but it was mounted)
Inverted shows it off nicely:
A little drab, even with the saturation pushed

imPPG does the heavy lifting once you have the RG&B. Assuming the focus is about the same on each, the fringing should be minimal
