Eta Carinae

[Moonman]

This is my first image run with a Modified 350D that I've just procured(Thanks David!)

It's just as well that Eta Carinae is not like my wife who hates being photographed for any reason.

This is a stack of 4 two minute exposures at 1600 iso. Stacked and stretched, sharpened, noise reduction etc in Nebulosity. Darks taken and subtracted. One of these days I'll get around to flats and bias frames as well.

Auto guided with a DSI colour with PHD. Imaging and guiding done with my two ED80's on a side by side bar mounted on an EQ6 mount.

Presentation seems to be determined by personal taste of course however any comments, tips and suggestions appreciated although try and keep it simple if possible.

Cheers

Good result Mike. That should make you happy. :)

I was under the impression that a modded DSLR got rid of the milky white colour in objects like Carina :shrug:

Thanks Ken,

Yes I'll have to do some research into what the DSLR modification all means. My knowledge in this area is limited. :question:

Cheers:)

A fine first effort Michael.

Can I suggest that you run that camera at ISO400 - I found the noise to be more acceptable at that rather than ISO800 or higher. The discussions about what ISO setting to use with DSLRs are about as clear as arguments for and against the legalisation of marijuana!

The images in the gallery link that I sent you were usually 10-15subs of up to ~7.5mins. Having the AC adaptor means a little less heat from the battery, so you can push the sub duration a bit longer.

Hope you get all the bugs ironed out before the Winter imaging season arrives properly!

Thanks David,

Certainly there's a lot to learn from and experiment with here settings wise.

I guess with the ISO its all about sacrificing spatial detail in order to minimize noise. Getting the balance right is most likely a subjective opinion but I have had at least one other mention that 800 iso is sufficient.

Cheers

Got to be happy with that one Micael, very pleasing result.
