Thors Helmet.

[tilbrook@rbe.ne (Justin Tilbrook)]

Thor's Helmet with an hour and twelve minutes of data.
This is a repro, and the maximum I can extract from the data. The faint back ground nebulosity showing up well.
This really shows the value of using ISO 6400 with a cooler box under dark skies.
8” F/4 imaging newtonian / astrograph , baader type 3 coma corrector,. HEQ Pro 5 mount, orion mini guider....
Camera.
Unmodded Cannon 1100D plus cooler box. 36 subs at ISO 6400. Stacked in Deep Sky Stacker .Processed in Photoshop Cs2..

Cheers,

Justin.

Nice one Justin always nice to nab an o3 rich target on a dslr for a change!

[RickS (Rick)]

Very nice, Justin!

[Cimitar (Evan)]

That's awesome, thanks for sharing Justin! Well done on your capture and you've managed the noise exceptionally well .

I'm keen now to give this a try with my DSLR using similar settings!

Cheers, Evan

Thanks Rusty!

Yep the old 1100D does well on O3.

Thanks Evan!

I reckon the most difficult part of Thor's helmet is taming the stars.
Look forward to your image.

Cheers,

Justin.

Nice one Justin

Really good. I had a go at that one the other night at long FL but the clouds rolled around 23:30 in and I got only 40min in Ha. As it's faint I've got bugger all. Well done.

Is there much HA in it?

Cheers,

Hi Justin, just realised you're using a cooler box with your DSLR. Is this something you built yourself?

Cheers, Evan

Hi Evan,

No the cooler box was sold by Orion, I purchased it through BINTEL'
Don't think they are made any more.

Cheers,

Justin.

Nicely Done Justin always like your star color work too
Im a little out-of-practice and/or bad memory, so forgive me if wrong but is this been cropped at all, , I cant think if this target would have fill your FOV ?
Sorry for the question - Im not up on progs at the moment

Actually I just googled and found it fitting in the field of a 16" f8 Hypergraph
So yeah, has been cropped which means your image is extremely good for your gear , being a crop and it is still very smooth and detailed - Very well done Justin

Thanks Bob!

About the best I can do, don't think there's much to be gained with more data on this one apart from killing some more noise.
How's your observatory progressing?

Cheers,

Justin.

[Shiraz (Ray)]

that's a really tidy result for such a faint target - as you say, the 1100D seems to respond well to O3.

Getting there slowly Justin, showers on & off for a few days here at the moment - then hopefully get some underground power & cabling capers happening. looks to be vastly cloudy for the next week or so - but thats suits me, for now _________
