That's an interesting solution for astrophotography.
What exposure times did you use & how many?

cheers

They were all 5min subs @ ISO800.
The cooling was turned off as I was having frosting problems (my fault not the camera's) the sensor was running at +14C. So I was very surprised at the overall lack of noise.

[alpal]

Really?

Where was it frosting?

[jjjnettie (Jeanette)]

Either on the sensor or the IR filter.
I'd left the camera on the back of the scope when I'd finished up one night, and it was quite wet with dew. I should have wiped it down and put it in a sealed bag with desiccant. It's all good now though. Lesson learned.

OK thanks Jeanette,
I think my QHY9 has a dew heater to stop that but
maybe the Canon doesn't?

[jjjnettie (Jeanette)]

No it doesn't. There is no control over the cooling either. The peltier is running full bore all the time as well.

[Octane (Humayun)]

babez, that's an outstanding result for such short integration time.

It's got a 3D feel about it and reminds me of a heart.

Yeah very nice. Really good details in there.

[Sirius1066 (Earl)]

Wow! Fantastic capture Jeanette. The detail is amazing.

Mind if I show it at the next Star Gayzers meeting as an eg. of some of the results of Astrofest?
