For the last few nights I have been working with the SSIc at f3.3 on my C8.  Conditions were not great and had to work around clouds every night.  The SSIc was not picking up much color as it can when under cloudless conditions.  I wasn’t initially using any filtration but on the second night I added in an IR cut filter and the weirdest thing happened; warm pixels cropped up every where so I eventually took the filter off and the warm pixels disappeared. See Jim Thompson's comments on this in CN forum topic: ‘Filters & Video Astronomy presentation’

 

The SSIm & SSIc are very low noise cameras and provide very nice captures with the ability to go as long as 2.5 min.  My SSIc model goes to 1.5 minutes, but I was using settings of 10sec to 60sec and gain was set between 12db to 15db.  Blinking and Blue Snowball was at 10-12sec, clusters at 25sec., M57 & bowtie  at 35sec., M27 was at 45sec. and the Bubble was at 60sec.

 

I’ve provided a link to my SSI Album where I have all of my SSI DSO captures from the last few days and 3 from back in Sept. 2013.

If you have an SSI it isn’t just for the Solar System, get out there and have fun.  I can’t wait till the conditions get better to try another night or two with the SSI.

Don,

 

Nice shots. 

 

Combine a reasonably sensitive camera with fast optics and someone who knows what he's doing ... and voila.

 

It's nice to have that additional resolution available when you need to blow up some of those smaller objects.

 

I wonder what Rock thinks about folks "abusing" his SSIc    :lol:  ... I can just imagine him jumping up and down "I didn't build it for DSO imaging" (I'm kidding of course).

Hey Don:  good looking captures.  As the camera isn't cooled I suspect you are right about the IR filter helping to retain heat.  At least you know the filter works ;-).

Please return to your authorized SSIc live view area inside of our solar system, and try some comets! I'd like to see C/2014 E2 (Jacques) if your able to. Very interested in what it will look like at higher resolution.

Thanks guys for your comments.   

 

The next time out with the SSIc I hope to attempt the comet.  It's quite bright so it should be easily picked up by the SSI.

Thanks Don, hope I can catch that, as you know I've been busy lately. Comets are one of the really fun things real time EAA allows one to do, that are otherwise difficult with other methods like visual for example.

Time to leave the Solar System for deep space. Nice images for a planetary camera. :cool:  :bow:  :waytogo:

Thanks Ptarmigan.  Hope to capture better images when we get better sky conditions.

Your welcome. Any plans on galaxies?

Galaxies are a real challenge for the  SSIc and I'll try for any bright galaxy when the skies are above average transparency.  Without filtration galaxies will have to be up high in altitude otherwise LP will be an issue.
