View Full Version here: : 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. :rofl:

:eyepop: What's wrong with that shot? Pretty awesome in my books. :shrug:
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. :D

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

I'd be more worried about the careless attention to framing.:P 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. :P

Framing? What's framing? I do Jazz imaging remember?

Yep....what he said. :rofl:
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 :D

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

Beautiful. :)
The 18-55mm works best between 30-42mm with the aperture closed down a stop, or so. :)

Well I've tried the same kind of shot with the same lens & your result is tons better than mine...I forgot to stop my down though. Makes a big difference with this lens!
Lovely shot mate!
