Eta Carina & Rosette core

[vic4loc]

Further imaging with my new QSI... tried some other targets tonight:

Scope: LX90 8" ACF with CCDT 0.67x reducer
Camera: QSI583wsg
Guider: Orion SSAG

Eta Carina
Ha: 5x5mins, bin1x1
RGB: 3x3mins each channel, bin2x2

Rosette core
Ha: 3x10mins, bin1x1

Calibrate, stretch and combined with MaximLE, further processing with CS5. Images are un-cropped, just resized to upload.

Now I realise how big Rosette is! took with the 0.67x reducer and can just barely fit the core.

Great stuff. So much detail!!
Are you liking the camera? Any dramas?

Thanks JJJ, so far I'm really happy with it. Still a lot to learn, with my limited knowledge of the camera's capabilities & LRGB processing, the images I have taken so far are 10 fold better than my Canon 550D :) And I have not even use it at a dark site yet. All these images up to date were taken from my Sydney suburban backyard.

It cools down really quickly, the lowest I managed to bring it down so far is -27C in this summer temp.

The OAG focus well for the Orion SSAG, I read on various forums that users were having problem focusing the SSAG, but I didnt have any of that issue.

The only drawback that I have is the long download time, 20-23 secs, which makes focusing & framing the target a long and painful process.
