So many nice juicy targets - I'd like to get them all.

cheers

Aaaah see?..but if I told you it would spoil the surprise huh? Besides, I have to pick something that I haven't imaged 12 times already

Yes Elio, this new camera system is a gem

I have a bunch of M16 data sitting on my disk not yet processed - but that'll be my first (well actually 2nd come to think of it, but the first isn't worth mentioning )

Well have to say the observatory is friggin awesome to have, it's changed my (recent) imaging life completely. It's not the exact observatory I'd have built had it been on my own property but it's a far cry from anything I've had had since July 2006 ...god, to think of the number of hours I have spent, packing, driving, setting up and pulling down in the last 7 years

Jase is totally right, ho hum. But, given yr improved image scale, heres a hint pros think is BS and cant work. Get different. Crop tight to the 3 sisters, or the tower, upscale 8 times in PS, thats right, 8 times. Process and sharpen etc, down size and post. Same image, different NF effect, much more fun.

Nice one, Mike! I won't hassle you about a galaxy image this time because I see it's already been done

Yep. Good tip Fred. Tried and tested. By working on upscaled data, coarse smoothing algorithms work their wonders. Selection is easier too, though zooming in can assist there. The trick of course is down sizing the data. Most pros will shrink in small steps and touch up as they go (smooth-blur tool or increase local contrast-sharpen tool). The reasoning behind this is photoshops bicubic resampling can have adverse effects. To me that's too much work so I normally down size in one swoop to the desired size (normally back the original size actually). Some may not be aware, but photoshop has specific resampling algorithms for upscaling and downscaling data;
Bicubic (best for smooth gradients) <--- default setting
Bicubic Smoother (best for englargement) <--- upscale
Bicubic Sharper (best for reduction) <--- downscale

Good information here where Bicubic sharper is used for both up and down scaling.

C'mon Mike, time for a Sidonio-reeeepro. Narrow Field?...with a Starfire comparo

Hey you guys are genius's now why didn't I think of that ...never in my 30 years of imaging have I EVER thought of that ....com'on guys, you really think me an idiot huh? I do that all the time, how do you think I got many of these

But thanks for the advice none the less

Mike

It might be a common object for some Mike, but what an amazing rendition.

Outstanding detail and really nice composition.

....time for you to start claiming a commission on this new camera, your recent photos are going to increase sales!..

Ross.

The NB rendition with artificial colours gives it a very different look and makes it easier to pick out the detail. Good one Mike.

I found CS6 to be even worse with downsizing as it clips the histogram. The best way to downsize that worked for me is in CCD Stack by doing a pixel math each step before reducing res.

That's a fantastic image Mike Bet you are happy with that! Looks to be a afir amount of detail in the pillars.

Noice detail Mike. I have an image like that colour scheme from last year. Never bothered to post it but probably should have.
