Wide field with Stock lens

A super wide field image taken last night.
More of an experiment than anything else. I used the Canon 18-55mm stock lens @ 18mm and stopped down to F4.5, the 550D was set at ISO 400. 6x5min using ICNR and flats.
Definitely NOT a good lens for astro work, but we knew that anyway. LOL At least now I can say this with authority.

What's wrong with that shot? Pretty awesome in my books.
I've stopped mine tonight and trying to do some stuff but I'd be stoked with a result like this one.

When you compare it to my last wide field of the region, which was only 10 minute more exposure time, you'll notice a lack of richness. There is severe coma present all around the edges, and if it was cropped out, you would be left with only a small image from the central portion. The stars lack sharpness and there isn't much fine detail in the image.
Oh, it's ok to use in a pinch, that's why I had it out last night. But if one is serious about making good quality wide fields, this is not the lens to use.

Fussy? You're in the uber-league then mate. I'm happy with my average shots. Keep up the good work.
PS: I'm going to develop a complex about posting my widefields now ...

I'd be more worried about the careless attention to framing. That is some thing Marc is working on, framing...... not being careless

Poor framing is due to the camera being in a fixed position. Wants....needs..... a ball joint type attachment.

Maybe a little, but fussy is good! I agree this image is smashing regardless though, really well done. I'm sure you know which lenses are more suited though, and I definitely think the Tammy, and well, probably most other lenses, will give better contrast and certainly sharpness (particularly for astro stuff I think) than the standard 18-55.

That said, you proved you can do it either way! Love it

I reckon it is terrific!

Because we see so many of the same thing over and over they start to become a bit ordinary. Not bad, just 'another one'.
But when I opened yours jj I went "wow, that's nice", then I said to myself "oooo, there's the Rho Ophiucus Complex", and stuff like that.

Which means I very much like it and wanted to look around in it.

Excellent, thanks jj

Thanks Dave, I hit the trifector on Monday. IOTW, Sky and Tel and EPOD.
Certainly was a moral boost.
