First go at Processing

Hi,

M42 and pleiades taken from Kinglake on Sat. The first all clear night in months. no wind, seeing and transparency were good.

Was the first night that my guiding, polar alignment and camera all co-operated so pretty happy with what I got.

One is a single 240s sub processed in photoshop with the core blown out, just wanted to see what was there.

second is a stack of a few lights in DSS and processed in startools, that did a great job of taming the core and bringing out details. this is from a screenshot, I haven't bought the software as yet, but will be.

No darks used, so a bit noisy. for some reason, my stacking with flats, bias, darks in DSS isn't working too well.

As for pleiades, I couldn't get all seven sisters in the frame, so just went with 6 sisters. just 5 x 180s subs.

All taken with an 8" F4, QHY8 OSC with unregulated cooling, guided with QHY5/finder guider, HEQ5pro.

Higher res versions

http://www.astrobin.com/full/24613/?mod=none
http://www.astrobin.com/full/24614/?mod=none

will now sit down and process them properly with darks, flats and see what happens.

I also got plate solving and autocentering to partially work. I should've used that to centre pleiades, I will revisit that again.

comments welcome.

Thanks John, Bo,

I want to try Pleiades again from Snake Valley with longer and more subs and the 10inch F4, its one of my favourites, so looking forward to it. Noise reduction in startools is really cool.
Stacking all flats, darks, bias with ccdstack is giving better results than DSS, might just be my settings in DSS. working on that.
Cheers
