Title: NGC891 - Another from Les Granges.. Sorry...!
Post by: JohnP on Oct 13, 2008, 11:37:00
Forgot I took this... :-( Main reason was my guiding was playing up again & I wasn't happy with result but thought I would post anyway. It represents 15X3min subs (L only) through MN56 (the only image I took with this scope) using as usual my Atik 16ic.

If you look closely at 9'oclock position (left at edge of frame) I have also captured PGC9042 which according to Sky Map Pro is a Mag 16.4 galaxy measuring 30 arcsecs X 18 arcsecs...

Cheers,  John

Wow!!  :o

Suberb detail in that dust lane. It almost looks 3D.

Thks Mike,

I've also noticed that as well as the galaxy at 9o'clock position on LHS of image there is one just to the top right about 1 o'clock of core of galaxy. Looks even fainter but I can't identify it as Sky Map doesn't go that low...

Thks Robert/ Fay - I had to loose quite a few images because of guiding playing up.. still not 100% sure but I think I still have an issue with the MN56. I will give it another try at home one evening... The image came out better than I thought & I am chuffed to have got the two faint galaxies..

Fantastic, I agree with Mike, very 3d, especially the core

Thks Daniel... all I an say is its nowt to do with the processing that makes it look 3D - must have just been down to seeing on the night....
