M81 - Bodes galaxy
31st January 24 x 6mins - WO Megrez scope
6th March 21 x 6mins – Skywatcher ED120
Kit as in signature using Skywatcher ED120 and Modified DSLR 450D, CLS filter
Stacked in DSS & PS CS3
I'm not sure if this is an improvement on the one done on 31st Jan.
This was an interesting exercise as I stacked subs from two different nights using 2 different scopes with a different field of view. I wasn't sure if this would work, but DSS seems to have stacked OK.

The Sun:
8th March 2011
I took the following single sub using Hugh's refractor that we use for the Outreach sessions a Teleview 85 Apochromatic with his white light solar filter, using my DSLR which I forgot was modified, but after some photoshop this is what I got.
Modified DSLR EOS 450D
Shutter speed 1/800
AV mode ISO 200

There's some really nice detail in these images, Carole. You now appear to have quite a production line running 8)
Blimey, all seems easy now eh!
:-)
Did you see how many sunspots there were three days ago, LOADS!
QuoteDid you see how many sunspots there were three days ago
No I didn't unfortunately, I don't have a white light filter of my own.
QuoteBlimey, all seems easy now eh!
Certain aspects are getting easy Chris, but still getting a lot of noise in the images which I would like to eradicate but don't know why I'm getting it. Plus of course the on-going intermittent guiding problems - see other thread.

Have you started turning off the liveview yet during capture ?
QuoteHave you started turning off the liveview yet during capture ?
Yup, I've done that now Mick, but only since the above captures, so not had a chance to compare yet.

It's not just the liveview, you need to turn off the LCD so it doesn't light up and generate heat (and ruin your dark adaptation). On my 350D you push the Menu button repeatedly until the screen goes off, otherwise it comes on between exposures even if you've set the timer to turn it off after x seconds.
It was the LCD screen that I meant Duncan. I've had live view on the laptop turned off for ages once I start imaging. Having said that though the LCD screen as you say only came on between exposures which of course is now switched off.
On my Canon I just have to press the Display button and it switches it off (didn't realise I could switch it off until Mark mentioned it on Mikes new kit thread).
Carole
Very nice Carole, it's good to see the Sun making an appearance on the forum for a change. I hope there will be many more now the next cycle is finally starting.
I have some sun images taken last week!
Come on don't be coy, get them posted 8)
Very nice Sun & Crab Carole.
Thanks Fay
Carole
I've tweaked the Crab a little as I thought the background was too blue, as was the crab itself.

Ahhhh, told you there was some nice detail there! I like the re-process. I think it's brought things up nicely.
Thanks Phil.
