Eta Carina

[mill]

Have a Canon 10D to close the gap between the demise of the 40D and getting the QHY9.

Not modded 21x3 minutes, false flat and no darks.
Fridge temp on -2C.
Noise is almost none in the 10D at iso800 and -2C.
The most i miss is the HA sensitivity:(

Beautiful widefield Martin

Thank you trevor, will do the tarantula tonight :)

[desler]

Yes Martin


Very nicely done.

:eyepop: That looks hot Martin! I wonder if I can fit that whole field with my C11/Hyperstar now. Great colors you got there. :thumbsup:

[telecasterguru]

Martin,

Not bad for a stopgap imager.

Looking forwarding to seeing your QHY9 images.

Well as a stop gap that's pretty good, colour is nice and overall image balance good too, only thing is and I'm not sure if you can see it on your screen (very obvious on mine) we can see where you perhaps lassoed (?) the main nebula and worked seperately on the nebula and the surrounds :eyepop::ashamed:...have another look, if you fix this it will be a more pleasing image :thumbsup:

Thank you Marc. It would be good if you get a field like this with the hyperstar.



Thank you Frank.
I am looking forward to some imaging with an qhy9.

[mill]

Thank you Mike.

The only thing i have done is select the stars and then reverse the selection so i work only on the back ground and nebula and not bloat the stars.
It might have been the false flat i used to get a flat field.
Will do some real flat fields today and see if that will get rid of the effect.
The good thing is that i didnt need any noise filtering with this camera at this temperature.

Martin.

[strongmanmike]

Fair'nuf :), real flats walk all over artificial ones.

Wow that's good smoothness then, what improvements are you expecting from the new camera?

Mike

[mill]

The new camera will be the qhy9 mono with filter wheel, so it will be a dedicated astro camera.

This canon 10D camera will do for normal snapshots etc.
At the moment it sits in a peltier fridge and is big :P
Will do darks too tonight to see what they look like at -2C.

Martin.

[AlexN]

Looks great Martin! If you can do that with a 10D at -2c, imagine what you could do with a KAF-8300 at -20c :D

Looking forward to your QHY9 images!! :)

[mill]

Thank you Alex.

First i expect some images from you :)
We might be able to do a comparison between the sbig and the qhy9.

[danielsun]

Nice one Martin:thumbsup: be interesting to see the difference with the QHY9.


Cheers Daniel.

[Hagar]

Quite a nice image Martin, I just feel the nebulosity looks a little soft. Have you used a blur of some kind on the nebulosity to smooth it a little?

Nice stop gap.

[mill]

Thank you Daniel :)

I think it will be a big difference :eyepop:



Thanks Doug.

Nah i didn't do any smoothing on the image.
It might have been caused by focusser slip (still the original focusser on the scope).
Going to get an 10:1 focusser so the thing doesn't slip.

[Hagar]

Martin, My advice is to save up and buy a good quality focuser, don't buy a GSO they are just as ordinary as the original one.

[RB]

That's a terrific shot Martin.
The good old 10D huh?
This camera sparked my interest in astro photography when I saw an article years ago in S&T.
Soon after I bought a 300D and got started.

You've done very well with this shot, I really like it.

BTW you said "the demise of the 40D", what happened to the 40D, I must have missed it?

[toryglen-boy]

Hi Martin, thats a killer shot, nice even field with some lovely colours

nice one

:)

[mill]

Thank you Andrew :)

The demise is the dreaded error 99 that pops up on just about every Canon in the world :(
Mine was the mirror up motor that burned out and later when i replaced the motor, it worked for about four shots and the new motor burned out too.
Later i found out that the shutter was stuffed too :(
If i only could get past the error 99, i could use the camera via the computer because i can still get pics from the cf card and eos camera control pops up when the 40D is connected (this all without shutter,backpanel,mirror box, top and lcd display).

[mill]

Thank you Duncan :thumbsup:

I too like the colors :)

[mill]

I finally uploaded the full res picture 1Mb here --->>> http://i605.photobucket.com/albums/tt137/Martin_Meupelenberg/etacarina10dlarge.jpg

[Tamtarn]

The full res sure highlights the detail and nebulosity captured Martin. Super image :thumbsup:

Would it be possible to post an image of the camera and fridge :question:

[mill]

Thank you David and Barb :)

Here is the picture of the cooler box on the scope that is inside at the moment because of the heat.

[Tamtarn]

Thanks for posting it Martin. Looks a great rig. :thumbsup:

Our scope is inside as well for a few days 'til this heatwave disappears :scared2:
