Hi all,

Just enjoying going through some galaxy images I haven't yet processed. Sure they're short but that just leaves the intrigue of what longer exposures would produce :)

Impossible to pick a favourite I think :)

PS. Not shown to scale - each cropped for it's own aesthetic appeal.

Regards,
Roger.

that is a great idea to do roger, i might keep them for reference in a folder on my desktop
i always get too stuck wondering which will be the "nicest" to photograph!
you image galaxies at f/10?

I used to have available PDF's (and printed equivalents) with ~2000 for just that purpose Pat, will probably post on IIS when I get that happening again, as I've been working on an improved version the last year, on and off.

F/7.5 - about 2180mm focal length, or 0.84 arc seconds/pixel.

Thanks for that Roger. Its nice to have a catalogue of interesting galaxies that would be worth the time to invest in a long image.

Great collection, be great to see the full version - very useful :)

You could be the forward scout for us imaging time wasters :P

A good reference if you have a go at supernova spotting...

nice details in all images.

that would be fantastic if you could do that for us roger, we seem to be getting less and less time in perth either because of both inclement weather or moon, so your great catalogue would certainly save an awful lot of time wondering!

Thanks everyone, I'm very happy that you're all enjoying them so much :thumbsup:



My supernova reference images is actually a separate set and 3,506 strong ... but that's another story for another time, I'm not currently doing supernova searching :)

Very good Roger. Gives me a list of targets for my new Meade F8 SCT

Dave, I often think that when looking at my Clear/Luminance frames - ST8 pulls good data. But then I go to do RGB and BAM! there goes my sensitivity and the RGB frames turn out weak and noisy :( ... anyway... I cherish the detail in the L shots :)

I'll see if I can upload a more recent file .... being from April most of these are 1am-4am objects currently :)

Here's a more recent set of galaxies, for RA more likely to be above the horizon at a suitable observing hour currently. :)

That's a lovely project, and great for ideas of what to have a go at (if the skies ever clear!). Thanks :)
