The last completed image I have managed:  not a sniff since mid-November.  I notice Another Forum has posted some data of this area for folk to play with, but this is all my own - hence the grainy, noisy background.  The only workable narrowband data was in H alpha: I got zip from my Bortle 6 location in SII and OIII, with colour coming from RGB (with a big selective stretch in B).

I think this run of cloud is unprecedented - I can't remember anything like it in the last 15 years.  Global warming I suppose...:classic_sad:

Not sure about global warming. It's -12 here, and a real feel of -24. I know what you mean though. Not had one clear sky since November. Usually get a few really clear nights in winter, and the sky is pitch black.

I think we are due -5 in SE England on Weds, guess that's tropical to you guys!

Summer weather! The weather here can be ridiculous. Two years ago we had a metre of snow on the floor in April. In the second week of April it went up to +30, with snow still on the ground.

We get 5 cm of snow and it shuts us down!  Still, if global warming predictions are right, the UK will start seeing Ukraine-type weather in the future...

In Ukraine we have distinct seasons, unlike the UK where you can have all 4 in one day. I remember when I lived in the UK, going to work one morning in June, and it was -2.

I've been following some of your amazing build projects, stuff I couldn't even begin to do. Could you build a cloud zapper?:classic_laugh:

 

Wish I could - I'd make a fortune!!  🤣

Lovely image, hope you can get some more data to help smooth out the noise.

I don't plan to go back to this one - the noise arises from the monumental stretch I had to apply to get this one to show any detail, particularly in the blue colour channel.  Interestingly, I note that the IKI narrowband data (garnered from more and longer subs from Spanish skies) on That Other Forum also gets a bit noisy when you stretch it out, so I don't feel too bad about my own effort.
