Two Left Feet

[jjjnettie (Jeanette)]

Rick Stevenson and myself now share a banner as winners of Picture of the Month on the "Disciples of the Dark Arts" group.
Rick won the CCD section, I got the gong for the DSLR section.
It's a real honour to have been chosen as there are many other talented imagers sharing their work there. I know some of the members also belong to IIS, so thanks.

I was wearing my freezer suit while imaging, so I should be thanking you too Geoff. Couldn't have sat out there all night without it.

Congrats from me too, JJJ! I must have surfed in on your tailwind

[GTB_an_Owl (Geoff)]

yes - they are a very important piece of gear jjj, especially for those that want to make the most of their astro experience

best accessory i ever purchased

Great comparison images, and very well done to you both.

Would it be possible to give a brief run down on the capture and processing techniques and why they look so different please, for us complete novices?

Thanks, Geoff.

I used a mono camera with filters. Jeanette used a DSLR (one shot colour sensor) and much shorter exposures. There's a reasonable difference in FOV due to differences in focal length and sensor size. I expect our processing was fairly different too since we used different software.

Details for my image were:

Mount: Astro-Physics AP900
Scope: Tak FSQ-106ED
Camera: Sbig STL11K, Astrodon Gen 2 filters
Guiding: Tak FS-60C and Lodestar
Focuser: Atlas
Exposures: 54x300s Lum, 14x300s each R, G & B + some 30s subs
Processing: PixInsight

Cheers,
Rick.

Congratulations, guys.

I should participate in that group a bit more.

Thanks Rick. There certainly seems a lot more dark in your image. Is that processing or the natural tendencies of using mono and filters with subs?

Thanks, H. It's a good bunch of people and you get to see a lot of northern objects.

It takes a lot of exposure time to get decent signal to noise ratio in the dark areas and a cooled camera, longer exposures and doing Luminance with a mono camera certainly helps. It's still possible with an OSC camera, though. I also tried deliberately to bring out the dark stuff, so the processing has emphasised it as well.

Cheers,
Rick.

Great to know. So much to explore and learn.

Congrats JJJ and Rick! Long live the Great Foot I've requested to join the group, looks like a good place to learn more about imaging
