M83 and N5128 from Sat night

allan gould · #1 16-06-2009, 12:16 PM

I was interested to see what my C8 would produce as an image scale with a f6.3 reducer and the dsi II Pro. Had a go saturday night and these images are essentially as can from the DSI after alignment /drizzle with Nebulosity.
M83 is 13x1min while N5128 is 37x1min. Slight sharpening in PS, and initially had a few guiding issues due to a (too well) balanced mount

Nice one's Allan.
For some reason there is a fobia of B/W images around here, given the equipment they're not bad at all. I appreciate the simplicity.
Well done.

Really nice detail there Allan. I think the image scale works really nicely with the DSI II. Also very smooth with the processing.

Fine effort

Nice pair of images Allan, What has happened to the QHY8?

You keep asking about it but I havn't had a chance to get to a dark site with power to test it out. Maybe this weekend.

They have potential Allan and will look better with more subs. Did you focus with the Bahtinov mask for these? The stars in the NGC5128 image look like it might have been a bit out of focus to me.

I did at the beginning of the session but by the time I got my guiding issues sorted out the scope had gone over the meridian, the mirror flopped and I was too tired to give a dam after that. I know lazy, lazy, lazy ut I really wanted to see what the image size was of the DSI with 8".

Thanks for posting these Allan. That exact image scale is of particular interest to me

How's my scope going? Using it yet?

Have been a little busy. Had it out one night only. After some quick visual, tried to do some imaging but had all sorts of problems with cameras and software. Didn't manage to get anything done. Not the scope's fault, though.
