Eagle CDK17

[gregbradley]

Again very late in the season for an Eagle Nebula shot and low in the sky.

Still, its the best I have done so far on this object which has been somewhat elusive for me
to present a decent image. I think it works best without Ha added - perhaps that is the key to it.

Good stuff Greg - there is a mile of nebulosity surrounding it too - as well as the internal detail - in only 20 min. Aahhh for aperture

I am at AIC in US at the moment (started a thread in General Discussion)was talking to Allan Keller and the guys from Planewave about an hour ago they said to say hi. I was just drooling over your scopes twin. They have a selection here. Amazing scopes (yours is definately woking)

That's cool Mark. Say hello back to them from me.

We are so international these days. Yes it is a great scope. I am still getting used to it and how to get the best out of it. A lot of potential there.

They also have a cool reducer for this as well that will take to F4.5 or so. I'll have to get that one day too.

My we are getting busy. If thats what your rig can achieve in 80 mins (:eyepop:) you will soon be pumping out 10 images a night. Time for some really big mosiacs I think Greg :thumbsup:.

That's very impressive for a quickie. :thumbsup:

[Lester]

Thanks for the view Greg. Just wonderful.

[strongmanmike]

Greg, can you map the entire sky above in 3 days..?

Ah huh! The Bradley LSST (http://www.lsst.org/lsst/gallery/telescope)is here! :eyepop:

Excellent for a point and shoot :thumbsup:

Oh... and is this (http://www.lsst.org/lsst/gallery/camera/camera_labeled) your camera (64cm image circle:eyepop:)

Mike

[issdaol]

Not Another One!! :eyepop::thumbsup:

We would like your exact address details, the times when you are away from home and your lock and alarm codes (otherwies leave a spare key under the mat) :D

[batema]

That is stunning. Can you imagine with more time. You must love the scope.

[gregbradley]

Thanks Mark.

I intend to routinely do longer exposures. The rainy weather of the last few months has made that not too practical. But there'll be a clear patch sooner or later.



Thanks Marc. Size does matter!



Thanks Lester. The Eagle has been an elusive object for me. I've imaged it many times, this is the first time I have been happy with the result.



Hehehe. There is a reducer available for this scope as well. Takes it to F4.48. Later on.



Hehehe.



Yes I like the scope. I am learning also how it responds to different conditions and how to get the most out of it. Like anything new.

Greg,
All the images you have been pumping out lately have been great. Keep 'em coming.
It's hard to see where you can go from here equipment wise. Please don't buy the stuff in the links Mike posted :P

Greg,

Another wonderful image, I love it, man! Your recent pictures have been a real visual treat:eyepop::D! Thanks a lot man. Could you maybe show me (us) one of your original pictures?

Clear skies to you

Greg,

Stunning image mate! Glad all the equipment is starting to sing now. :thumbsup:

Mark

[gregbradley]

Hehe, I hope its not too late to cancel the order then!
Thanks James.



I'll post an unprocessed luminance subexposure if you like.



Thanks Mark. I am getting the hang of this new scope.

[Hagar]

Nice detail greg particularly for such a short exposure. On my monitor the background does seem a little red.

Well done.

[gregbradley]

Thanks Doug. I have shot this one several times and it usually has a reddish background. Usually though I have had to take quite a bit of Ha to show this but it has gotten picked up by the large aperture. I think this is fairly accurate and I haven't gone out of my way to process it that way. But colour is something that is easily shown incorrectly so who knows. Put it this way, the histogram was balanced and I didn't push the red.

[Octane]

Wow, what an impressive field.

Once again, Greg, wonderful!

[gregbradley]

Thanks Humi.

I wonder how you get into the 1500 club;)

Greg

[Octane]

lol!

It's not even worthy of 1,500 (the Snake, that is!)

[gregbradley]

Oh so humble! :rofl:

Its a beaut.

Hi Greg

I have looked at all of your latest CDK images, and I cant wait to get my hands on one of those scopes. Thanks for posting.

Only one comment on this particular image - the stars are largely burnt out, and I dont know whether it is your processing technique, but a number of them appear to take on bit of a rhombic shape? Is the CDK prone to mis-collimation easy or does it hold it well?

Otherwise, a fine image indeed.

cheers

Crikey Greg, there's *nothing* wrong with that image, awesome! That's one of the best M16's I've seen for a while.

Dave

PS totally jealous of the scope, camera and mount, so not fair!!!

[gregbradley]

Hi Martin,

When I mounted it and took the first images I checked CCD inspector and it showed collimation as being accurate from the factory. I haven't collimated it yet as it was perfect. It isn't moved, it sits on its mount and images look the same now as then so the collimation should be fine.
I hadn't particularly noticed odd stars but probably a consequence of the spider as usual with any compound scope. I may need to do shorter
sub exposure times. 17 inches collects a lot of light.



Thanks Dave. It sure is an unfair advantage.
