Title: An old favourite - M31 from Petts Wood
Post by: Roberto on Oct 22, 2019, 09:07:57
Work in progress still.  I have L data and some colour but with the bright Moon the balance is not right.  I need to take colour data later this week and finish.  This is my third attempt at this subject.

That's come out well Roberto.  Looking forward to trying out that Idas Hutech filter you recommended this winter from Home.

Looking really good Roberto
I make it 9 or 10 galaxies in one picture.

Well done.

Beautiful.

That's really lovely Roberto.

BTW have you changed camera or just glued a few pixels on the side ?

Hi Robert

Thanks!  Same camera (as in previous two versions) - 4K x 4K pixels.  The galaxy still does not fit at my pixel scale (1.4"/px) so maybe should have gone for a mosaic.

Hi Robert

Yes, as per the Astrobin acquisition details:  https://www.astrobin.com/kbmr1e/D/?nc=user  I've had it since 2015 and it works really well.
Thanks
