Struggling with LRGB from Bromley and no NB targets around.
Had "great fun" the first night I tried to image this as I got some awful artifacts after processing, and after discussion on SGL I concluded that it was ice and I needed to change my dessicant and dry the camera out Did that and it seems to be OK now from that point of view.
Background gradients and LP forced me to combine the data with the old image done in darker locations.

Here is a better colour version:

Terrific framing Carole
All those galaxies!
Noel
Thanks Noel
I probably need a bit more data as some of the galaxies are a bit noisy if you zoom right in.
Carole
The second version has much better colours. It's a good result from the suburbs.
I last imaged Markarian's Chain back in 2012 with my old Canon 350D during a run of 10 successive clear nights:

Funnily now in 2020, this last I also shot a few nights of data with my Nikon Z6 but I haven't yet processed it.
Mark
Thanks Carole
A really lovely picture of such a wonderful chain of galaxies!
Hugh
Thanks Hugh.
Mark it is not really surprising we both have done the same thing, we are a bit limited for choice at the moment unless you have a set up suitable for tiny galaxies.
I look forward to seeing your results.
Carole
I have a massive processing backlog from 8 clear moonless nights in March and 8 clear moonless nights in April.
Mark
Wow!
Are you working from Home?
Carole
Very good Carole! Extracting any colour from these faint galaxies from sub-urban London is very difficult.
Roberto
Thanks Roberto, you are right about the colour.
Carole
Nice images.
thats what i was aiming for, but as i didnt have my laptop set up, mine was a point and hope,
Fingers crossed over the next week or two i'll get the laptop set up again, at least that way i know its working for spain.
Mac.
Thanks Mac.
