Another Orions sword First light with new 40D

Garyh · #1 19-01-2010, 12:47 PM

Well I have finally got around to processing my first image with the new cooled modded 40D. Did this last new moon over a two night period with a total of just over 3 hours data. The 40D exhibited some banding in the darker areas which I am not sure of the cause, putting some ferrite chokes now on the leads so hopefully that shall fix that up?
Camera was set at a modest 15c with the ambient at around 20c and plenty of humidity after plenty of rain so left it on the high side to prevent condensation. Last night I ran the camera at 7-8c with no problems

.

Image stacked in DSS and done a little Pixinsight and finished in PS.
Reduced to just under 50% for upload and a decent jpg resolution.

Approx 600kb

Comments most welcome!
cheers Gary

i cant see it mate, it just brings up the IIS home page?

That is awsome. What a fantastic shot. The detail is striking and the core looks great! What were the exposure times? The colours are very nice also....

Fixed the bad link Duncan! That always gets me!

I agree with Duncan ...

It MOST certainly was a link worth fixing ... great result Gary .. everything spot on makes this image ... one of THE images of M42 this season.
Well done

iceman (Mike) · #8 19-01-2010, 02:50 PM

Well I'd be very pleased with that. What a beauty Gary!

Beautiful first light with the Astro 40D Gary.
I assume it's a Central DS mod or is it DIY?
Any pros and cons re using the camera?
cheers
Doug

cheers Jeff! Fairly happy with the result, but like usual I could have framed it better, always get this a bit lopsided for some reason!

Thanks Mike! Must admit it took a few hours to process but the data was pretty good except that minor banding.

Thanks Doug, It`s a DIY job actually, The only con at the moment is that I don`t want to push the temp too low as I havn`t made up a antidew system for it, and it weighs a bit now at 1.35kg, get some minor flexture with the focuser/tube, something else I will have to fix up.
With tests the camera cmos can get to around 25c below ambient. I shall have fun when the humidity drops down for sure!

Oh and the unprotected fan wants to suck my hair into it when focusing with liveview! Have to watch that one!

DavidU (Dave) · #11 19-01-2010, 04:31 PM

Hahaha ! What a beauty !

strongmanmike (Michael) · #12 19-01-2010, 04:47 PM

Wow Gary that's an excellent image, you have handled everything beautifully! The colour is nice, the core is very well handled...I don't think even I would feel the need to reprocess it..?...weeeelll

Top job, that camera looks to be a corker!

Mike

Garyh · #13 19-01-2010, 04:54 PM

Thanks Dave and Mike!
Reprocess...well actually?

I`m not the happiest with the colors....soo wait for the Repro!

The only thing I have to add is some very short subs like 5 sec ones as the trap was still burned out with 10sec ones.
Thanks Guys!

First class image there Gary - great depth & detail and the colour balance is very good. You've exposed some really good detail in the core too! Excellent!

Cheers, Marcus

multiweb (Marc) · #15 19-01-2010, 06:01 PM

Wow! I love the processing. Definitely the best trap/core blending I've seen around to date.

TheDecepticon · #16 19-01-2010, 07:02 PM

Very cool piccy mate! Great colours and detail.

AlexN · #17 19-01-2010, 07:26 PM

Pwoah!! Niiiice work Gary!

That looks fantastic.

leinad (Dan) · #18 19-01-2010, 07:47 PM

That's a beauty!! Gotta be proud of that process

The random banding with the 40D appears to be common problem with them all.
More noticeable with sudden fades in bright to dark areas; and during high temps.
Unfortunately I could never get rid of it, even with darks; as the banding seems to randomly flow through the image. You can see this more noticeably when viewing stacking flows in CCDStack; or timelapsed photos(avi movies).

Hagar (Doug) · #19 19-01-2010, 08:05 PM

Gary, this is a ripper, you have to be happy with results like this one. The overall illumination and colour give a very nice 3D effect.

Looking forward to seeing some more like this.
