Carina Wide Field

[Mosc_007 (Charles)]

The very Large Carina Nebula. Taken from my backyard in the Western Suburbs of Sydney. A Modded Canon 1100D using a 300mm Zoom lense. 10 x 30 Sec Subs. EOS CLS-CCD Clip Filter.

This was my first Image after I modded the 1100D myself.

Well done Charles, the difference with a modded camera is huge. when i modded mine I wished I had done it sooner.

So true. I couldn't believe how much more sensitive it is to Ha. Before the mod it only allows 10% of the Ha to pass. Now it passes 100%.

Exposure times are so short now on Ha Nebula. I do have one of Triffid and the Ha part is fine. But the OIII and Hb are non existant. No Blue from the reflection part of the Nebula at all.

How do you go for CA in the lens? After modding my camera CA became quite a problem.

Nice wide field there.

I have not noticed much of a problem. Most images are red anyway so it's not noticable. I image with the CLS-CCD filter so it removes the IR and UV which reduces it. I have had a Red Ring around some brighter stars but not noticed it often.
