Hope you don't mind Luke, but I flipped your image to compare the cloud detail with the sketch I made earlier this evening. I think there are enough similarities in position to convince me of the reality of the features in the visual appearance. Very bright visually of course!

Lovely sketch Mike.

Very nice image again Luke, some excellent detail there.

I have bought and sold lots of items over 10 years on Astro buy and sell, only had a real problem once, most people are very honest and reliable. A google search on the interested party usually shows whether they are a genuine buyer/seller. Unfortunately for me this didn't help, on the one occasion i had an issue 🙂   

Should be a fairly easy spot from even my light polluted skies. 

Good to hear everyone is ok! At times like this i feel like astronomy is more important to me than ever, a much needed escape from the terrible news around the world.

Phase showing nicely, i would also try the RGB align as well.

Some nice detail there.

Very nice Luke, plenty of detail visible there.

I guess if getting a sharp blue channel is hard enough, getting a sharp UV image must be tricky... Did you see my earlier question about sub length? Also I am guessing this is shot at native F10?

It wasn't at F10, i was using a X1.8 Barlow. Probably nearer F20 and a bit over-sampled. Focus is very tricky, even in decent seeing conditions.

ROI=640x480
FPS (avg.)=64
Shutter=15.52ms
Gain=350
Gamma=50
Histogramm=75%
Limit=25000 Frames

Whoops sorry Agnes, when I get home I will copy some of the capture file log and post it on here.

I've learned something - I didn't know you could do UV with an SCT because of the corrector plate absorbing the UV. How many milliseconds were the subs?

I read a lot about coatings and the loss of the UV signal. It seems that some of the signal is lost maybe, compared to a Newtonian telescope. Certainly plenty of detail visible when the seeing is ok though.

They do look very cool, i saw this one a few years ago from my back garden.

Superb looking prom, not much chance of seeing it around these parts 🙂

Some very nice fine cloud detail Pete, especially in the image from the 2nd. The image from the 3rd isn't to bad either. I know the umbrella experiance only to well😀

I must have looked a sight, crouched under a huge brolly seething at the weather 🙂

I was looking at these areas last night as well, a superb area of the moon!

Very nicely captured

Some lovely views last night

A fine set of images
