Apologies if have missed anyones post recently - work and sons exams prep taking priority just now.

Here is a look at M81 55 hours of data from the new AP RH 305 (that i have a vested interested in with my camera and filters hanging off the back :) will live there for a few years returning some photons from my equipment - unheard of over here!) + the RC data which i could not help throwing into the mixer.

Focused on the galaxy may return and have a look at what IFN is lurking in there, some subtle hints for now.  Some nice detail around Holmberg IX including some red which I had not noted previously.  To the lower right of the galaxy also appears to be a galaxy in front of a star (can't be so will have to look into that, maybe s little lensing or a jet of some sort)

Hope you like.

This is a beggar of a galaxy to get right and I never have got it right. Here you have preserved interesting and convincing contrasts right through the brightness range. Holmberg has colour.  There's flux. A bit of of killer, I'd say, Mr G! :icon_salut:

Stunning Paddy. Huge amount of galaxies lurking in the background.

Thanks - there are quite a few interesting little features lurking in their when examined in detail.  Some needing a bit of research!

That's a real stunner. Btw, a belated congratulations on your picture of the month (NGC 7331 and friends) in Astronomy Now, very well deserved.

Thanks on both counts.  Appreciate feedback.

Thanks Olly, always something to work on, the stars where a pain but managed to find some extra features I had not seen before, little emission was a new one for me.  Thanks for kind words.

Thats a stonker... about as good as it gets!

Thanks - there is always something to work on but pleased with results so far.

Thanks all, Paddy

Good spot on the nebulosity in Holmberg IX, I haven't seen that before either. Whereabouts is this anomalous galaxy/star please?

I like this Paddy - delicate processing on a core that is often nothing more than grey wavelets. A standard has been set :)

Thanks Sara - one that will be surpassed soon enough - but i'll take my 30 seconds :) - appreciate comment.

Just above HIX - on super zoom it appears to actually be in front of star, which clearly makes no sense.  Maybe some lensing, interacting galaxies or a jet?

Probably just an artefact but worth an investigation - 'tis how things get found after alll.

Mesmerizing.  Doesn't look like an artifact to me--certainly not a star issue as its the only one--be interesting to see if it can be duplicated.  I am currently working on M81 and I will look out for it.

It is [PR95] 50238 galaxy.  That said it is listed as 1 galaxy on maps but appears to be an overlapping pair or two.

On SDSS looks like two to me with the catalogued one @ 1.2 billion ly.

Glorious technicolour Paddy - great detail and it must be very satisfying to see data from your new scope and set up at last :headbang:.

Yes pleased seeing some return on the expense few and 12" @ f/3.8 is a nice option to have at a dark site.  Thanks for feedback on image too.

Beautiful image Paddy, 55 hours :eek: been working on the same target for a while and managed 15 hours so far LOL.

Offshore is that way forward, 55 hours data is exactly 54 hours more than I have managed so far this year from home.  Thanks for feedback.

Paddy--I checked and believe it or not it is in my green channel image!  I was surprised.  It is not as well formed, but it is definitely there.  Thanks for pointing this little jem out

Awesome work! Probably one of the best amateur images of M81 I have seen.

Couldn't agree more, this is absolutely superb, having been (badly) attempting 81 and 82 over the few clear nights last week I take my hat off to you Paddy (again)!

Keep up the good work
