Stargazing Meade's new DSI Pro II

    I recently bought Meade's new DSI Pro II, which is a black and white camera of higher resolution and sensitivity than my last camera. Below is my first lrgb photo with it. It is a lot of work to take many separate exposures and then combine them, but the results are good. I'm really limited by my equipment here - with my telescope's tracking bug, I can only keep about 1/3 of photos of 30 seconds exposure, and I can't do any longer. So this photo is heavily processed, which is why the contrast is pretty low. I'm really itching for a new scope, and it'll probably happen before the end of the summer.

    Anyway, this photo is M-51, the Whirlpool Galaxy, a relatively nearby neighbor. For the luminance data, I set up my scope on my deck and went to bed! I love my new house...

    Is that what gives it that grainy look?

    Sounds like you're enjoying your new house and living where it's dark at night. :approve: I always enjoy the updates...love the pictures. Sure you don't want to drive several hours out of your way to show me some of these views in person? :biggrin:

    Yes. It is tough to amplify the signal without amplifying the noise. To give an idea of how little good data was in the origionals, attached is an unprocessed luminance (b/w) frame.
    Yeah, like my house and deck. We'll see about the drive - I may be buying a new telescope this summer.

    Wow, that starts out pretty dim. Now I can see why you lose quality in order to enhance the brightness.
    Hee, you're always so cryptic. Does that mean after buying a new telescope, you won't be able to afford a trip anywhere, or that once you have a new telescope, you'll have more incentive to show it off?

    The weather around here has been atrocious lately for even just plain old stargazing without a telescope though...for my first few days back last week, it was disgustingly hot and hazy, and then changed to dreary, cloudy and rainy for a week. It's definitely dark enough, but you can't see anything through the cloud cover. This is not normal spring weather. :grumpy:
