Orion starshoot G3

Postby westernwolf » Mon Feb 02, 2015 3:25 am

Hi
I am starting out with astrophotography and have a quick question with regards the Orion StarShoot G3. The price for starting out seems reasonable for me and most reviews are positive, the one thing I can't discern from the reviews is whether to get the colour or mono version.

I don't know if it makes a difference but the scope in use would is a Celestron CPC925, once I get used to using the camera I will invest in an EQ wedge for it.

Any help would be appreciated
Matt

That's a tricky question! You'll get a higher resolution with the b&w version and it will be more sensitive. But to get colour you will have to take two or more images with different filters and then spend the time to compose them into a colour image. Whereas, the colour camera will directly produce colour images. This is generally considered the entry root for beginners because there is enough to master with a colour camera without the agro or expense of LRGB filters and filter wheels.

Thanks for posting back, that sort of sums up the dilemma. I stumbled across a sit where there were some sample files with each colour already stacked to aligned into 3 images. Was playing around with them on the train home this morning. I hope that I don't bite off more than I can chew, but think I'll take the harder route of monochrome, even though they weren't my images it still gave me a sense of achievement creating a colour image from the three greyscales.

I think the mono would be better for hydrogen alpha photography, either night or solar. The Bayer Matrix is a pain in the <expletive> for light of a single wavelength.

Not that I've tried it yet but I think using specialist filters, such as hydrogen alpha and Oxygen III and combining them would look good and I think that's how they do many of the Hubble images.
How can I be one with the universe when we don't know what 96% of it is.

Ok, so I was going to buy an Orion but after talking with the guys from Atik at Astrophest the other week I got quite a good deal on a 314L+. Been getting used to the software, however clear skies have been eluding me at the moment when I'm not working, will let you know how I get on.

It's been a while, but finally got some clear skies when I wasn't working. In the end I purchased an Atik 314L+ (though I still need to get sorted for LRGB imaging), I also decided to get the Orion G3 for those nights where I know I won't have too much time, whether it is the weather or work etc.

I still have a lot of work to do playing with the software for each camera, but I thought I'd add a couple of what I have done so far images. I was a bit hampered by the weather, blowing a mini-gale and light pollution is also a factor.

The image was created from 5 40s exposures combined in the Orion software.

This was a single 45s exposure.

I know they're not great images by any standard, but I'm learning and always open to comments, advice etc.
