Squark!

Polly wanna cracker? (well, not a cracker image!)

Yep, 47 Tuc. Was a complete test of my "start all over again" setup - Vixen SXP mount (had to test goto, guiding etc), Tak TSA-102S with TOA reducer-flattener, Lodestar guiding through a converted Tak 7x50 finder, and a totally refurbished SBIG 8300C. Grand total of 50 minutes under a 3/4 Moon and horrid airport light pollution (Baader UHC and UV/IR filters in the train). Hand focused with an f/8 Baht, but good enough lol. Polar alignment was off a fair bit, but the SXP didn't give a damn - it just works, SUPERBLY.

Not a single calibration frame at all, so this is dust motes and vignette at it's best, but apart from that, can you see any glaring major issues? (the stars are not perfectly round as I incorporated a ****ty sub in there and can't be bothered restacking because...well, I don't give a carp since this is just a test, not keeper data).

Severe criticism welcomed - but if you tell me about the vignette, dust motes etc and the need for flats, darks and bias I will raise my virtual middle finger I just need multiple sets of eyes to see if there is anything glaringly in need of attention (tilt etc) - don't ask me to quadrantalise it...I am not dorky enuff to be bothered yet.

Here is this superb piece of fart at 1/3 size: http://www.astrobin.com/full/315054/0/

And the piece de flatulence in craptacular JPEG-ness:

Looks ok Lewis. Pretty good for slacker focusing ( still soft, mind you)and seems flat enough.

The image scale is kind or weird on astrobin, 5 point something? You could drizzle the data to get something lower and stop the stars from being squares?

PI will do a reasonable job with no more than say 15 subs as an example so might be worth a go when you stop doing test images. Not sure what other software would let you drizzle.

When you can be bothered to process it properly, push the saturation up to get the star colour back.

And stop telling us how Carp it is..we might not want to look

It could do with flat frames to take out the blobs

It's shrunk in PS to 33% and I just used bicubic sharper reduction, so yeah weird figures and squarish - I'm not uploading the full size mess
