1st light on SBIG OSC

Hi everyone,

After months of tearing my hair out, I've finally got my head around some of the complexities of imaging with my SBIG 8300c CCD. This result is from a few stacked 5 min exposures and darks, guided with PHD, Orion SSAG on a 120 ED refractor, mounted on an EQ6.

With special thanks to some good advice from an experienced ASV member, I've managed to capture & pre-process this with Nebulosity on the Macbook, and post process in Photoshop.

Still a long way to go, I know... and I need to get a better focuser and a flattener.

BTW: What do you recommend for dew heaters? It's chilly in Melbourne right now.

Thanks for looking

Warmly

Andy

I think it looks great. Good colour and smooth for only a few shots. Well done.

Nice start Andy. Suggest you try at least 10 minute subs, this will see the S/N improve quite a bit.

Hello Andy,

That's a fine start indeed! Longer sub exposures will smooth out your data, just as long as you are comfortable guiding for longer periods. There are a few economical dew heater solutions, perhaps the entry level kendrick unit with the 4 outputs, and 2 dial controls, combined with their black range of heaterband would be good. Their blue range uses a lower quality resistance strip that is far less durable.

Regards

Steve

Andy is this a the full frame from the camera or a crop to one side? It looks like something in the scope is misaligned. Notice the stars are sharper on the right than the left? Or if it's just a crop from the side of the image then it's really just a case of a flattener.

Also your image has a bit of a green tinge. There's a free plugin for Photoshop that nails it in one button press that I used early on here: http://www.deepskycolors.com/archivo...sta-green.html

Otherwise a respectable shot!

Hi Everyone,

Thanks so much for your kind words, much appreciated It's very nice to get some positive results and encouraging feedback after trying for so long to get a result.

I'll see if my rig can hold up with longer subs, but as I'm shooting from suburban Melbourne, I might have more success with that under dark skies - but I'll give it a try at 10 mins.

Garbz, the image was slightly cropped on the left hand side. Agree a flattener is required, any recommendations? Unfortunately I can't use HLVG as its written for PC only and I'm a mac guy.

Warmly

Andy
