NGC253 Close up

[Martin Pugh]

Great detail in that image Fred - you could of course help alleviate those big star problems by shooting your colour unbinned also.

That ST10XME you bought from me is a sensitive guy.

Very nice details and tak sharp Bassnut, well done indeed!

Just beautiful! Lots & lots of detail - the processing is spot on and exactly to my taste (except, if I'm nitpicking, a faint blue gradient/block/artifact in the bottom half and the odd hot pixel).

Awesome stuff!

Narrow field rules. Good to see you keeping the faith

One of the best shots of 253 I've seen....fantastic work, Fred

I agree, I am a big fan of colour shot in 1x1 and have made the switch. I get way better resolution plus you can desaturate your RGB and use it as additional luminance (not sure it makes much difference if any though).

With my refractor there is quite a big difference in resolution that is noticeable in images between 2x2 and 1x1 in RGB. It is more apparent with shorter focal lengths - something you won't have to worry about!

I reckon if you rotated the camera by about 30° you could probably have gone for a SLIIIGHTLY longer focal length.. haha

Oozing......... I like it . that would be a "refractor"... killer ? , but no, im happy with it. I was stuck with that composition due to only one suitable guide star.

Should be for the money spent , thanks Phil.

Thanks Martin. The lum blooms heavily even bin 1 . Bin1 colour means double the exposure time for a given S/N ratio unforch, I just need to get better at processing bloomy stars.

Yes, yr ex ST10 sure is sensitive, Ive still got it cause I cant find a better one (QE, AO etc), looking forward to an STX 6303 in the future maybe. The 3nm Ha you also supplied me is my secret weapon, best filter I have, its awesome, but requires hi QE and megadata to fly, hence me sticking to NABG.

Thanks Marco, dunno about TAK sharp , but not bad for the FL.

Thanks Ivo, I must fix that, damb it, so stupid to miss

Of course, is there any other ?

Thanks Carl, but oh for dark, stable skies

At my FL, bin1 is 0.62 arc/secs and bin2 is 1.25 arc/secs, so ive even considered binning 2 on Lum on dim stuff, given seeing is rarely better than 4 arc/secs, im hard pressed to tell the diff usually. It would make a big diff with short FLs I guess.

Someone recently mentioned not using lum at all and taking just RGB at bin one and lots of data for all filters. Thats an interesting idea, must try that with a bright object, the quality diff might be worth it.

That is an interesting idea. I remember a posting by I think it was Roland Christen of AP saying the same thing about getting maximum resolution.

Daniel Verschatse has some nice high quality RGB shots on his site. He obviously experimented with that as well.

I'd be curious to see the results of that idea.

The 2x2 binning on colour I noticed on my FSQ with reducer at F3.64 and it was a major difference. I guess that is the number of arc seconds/pixel thing being so poor at F3.64 with small aperture.

Fred,



Mate, nothing to apologise for, I know you're just a cheeky bugger with a penchant for narrowfield! If I had the funds, I'd join the party as that is also where my joy lies. : )

OI! don't blame me for your substance abuse



And..I still have big stomach bones

[Bassnut (Fred)]

Sigh, no, its not substance abuse, its substance guided/boosted (mostly) Sid abuse, someone has to do it, its a community service .

Nice work Fred. I can see the streamers on my screen and the saturation looks pretty good. I don't mind the star size either. Certainly up to your usual standard. Well done.
