ASI094 First Light: Eta Carina

[Atmos]

With a great weekend up in Coolah last new moon I decided it would be a good time to see the first light of the ASI094 I bought off a fellow IIS member late last year. Didn't use a UV/IR filter and was curious as to whether it would be noticeable. Let me tell you... It is! Star bloat is a real thing :lol:

With just shy of 4 hours of exposure under the pristinely dark skies of Coolah I don't think I'd need any more exposure to make any difference to SNR. The background is smooth without any noise reduction.

I do have some tilt towards the bottom right corner that I do plan on addressing with the tilt adapter on the ASI094 but I'm awaiting on some adapters from Joshua before I can do that.

That's a big wide field. Nice!

HI Colin ,
Thx for the share man. I do recognise the FOV;) Nice color and the "Close up";) FOV is reminiscent of my shot through "Zamar".

Very nice. Lovely colour.

Greg.

Big CMOS chip certainly helps :lol:



Zamar was a little more monochromatic :lol:



Thanks Greg :)

Nice colours, can't comment further though as the link to high res appears to be broken? :question:

Great image, Colin. I can see the advantage of hours of exposure compared to my stacked 30-second images (on Nikon D850) of Eta Carinae. Well done.

Thanks Andy, link fixed! I must have accidentally put a “ in there for some reason.



That’s not to say that you can’t have a lot of fun with 30s shots of objects across the sky, you could knock off most of the Messier catalog in one evening that way :thumbsup:

A quality Eta rendition.

As others have commented, great colour :thumbsup:

Very very nice!
Cheers,

Is that actually a 4 hour exposure??
what was the camera gain settings???

[Atmos]

Thanks Peter, doesn’t quite have the depth of your AP305 but it is a straw with a OSC :lol:


Thanks Tim :)



It’s not a single 4 hour exposure :) 47x300s at 0 gain :) Could potentially get that much exposure with film and that could be an interesting experiment. The skies were pretty dark!
