Hi All,

A bit of fun with the Trifid and Lagoon Nebulas (L to R respectively) using my son Anthony's Canon 6D DSLR combined with my ED80, Orion 0.8x Focal reducer and CLS 2" Light pollution filter from last night. Cropped about 600 pixels on each edge to remove some horrible vignetting from the too narrow T ring that connects the scope to the full frame 6D DSLR. An interesting test of the Field of View using a DSLR. Only a 30 min (10 x 3 min @ ISO 800) test, with 10 flats used. Man, what a view compared to the narrow Atik & Newtonian combo. :)

It was fun using Backyard EOS again and it took me a while to get Stellarium Scope and PHD playing nicely on my new Windows 8.1 work laptop, so I didn't get as many exposures before I had to head in to get sleep for work. I forgot just how much disk space DSLR files take up plus, how long it takes to process.

Nothing bragworthy, but certainly something fun to do, even if it was just to see what could come out the other end.

50% reduction on the size for the JPG thumbnail below, the full size pic is on dropbox here (2Mb JPEG) :

Cool Chris, you've done a nice job with the colour balance considering the CLS filter. Do you have to do a lot to recover it?

Cheers,
Cam

Hi Cam,

Thanks, no, not too much to sort it out, first I use "Adjust Colour Background (offset)" in Nebulosity and this balances the channels quite well, then I normally boost the saturation to taste.

Glad you liked it :)

Cheers

Chris

That's a pretty nice result and esp. using untested gear.
I understand you comment on the files sizes. I am taking about 40-80 fungi shots a day this past week and when I looked at the total folder size I could see a drive upgrade in my future :-)

Lol Trevor, yes, it sure does sneak up on you, doesnt it? 2.8GB of RAW files for only 20-30 shots is pretty funny once you add in all the autosaves and stacking files that DSS spits out. :) The Atik makes wee little 2.6Mb tiff files which are a doddle to store and process. My new i7 Win 8 pro quad core laptop with 256Gb SSD drive and 8GB of RAM sure did slow down a lot processing these.



Cheers Laurie, thanks :D
