I did a shakedown cruise of my new setup and discovered I had a part pushing the camera adapter forward causing the top 1/3rd stars to be a bit out of focus (since fixed it).

I now have everything working and it seems reliable.

Planewave CDK17, FLI Proline 16803, Starlight Xpress Lodestar autoguider on a MMOAG.

The Planewave has its own electronic focuser, fan and temperature control (it takes about 1-1.5 hours to equalise). The focuser works quite well although finding exact focus is not as easy as the refractors that snap to focus nor as easy as the RCOS I had. It isn't that hard either.
But it does seem to shift sometimes with temperature a bit and doesn't seem 100% repeatable. Then again it does work but you have to work it a bit. Perhaps I will add FocusMax to my routine to help there.

Otherwise it all seems to work according to their website and seems well made.

The Paramount does it job easily and is by far the best mount I have used. Also it is very easy to use and user friendly being so tightly integrated with The Sky 6.0. The Paramount throws this scope around like its nothing yet it weighs about 40kgs with cameras etc.

CCDSoft was used for acquisition.

I haven't had a lot of clear nights here, where it was clear all day then suddenly formed cloud at dusk several times.

This scope also (like any really) seems to need dark skies as the large mirror really scoops up the light including moonlight. Baffling could be improved as nearby bright stars can flare. It seemed even Ha during moonlight nights was picking up too much light pollution.

Here is a photo of the setup:

Overall I am very happy with this scope. I can see an AO device may bring out more with it. It will also need dark skies and good seeing.
The autoguiding works well and is easy now it is setup. No trouble getting a guide star so far.

With the ML8300 camera, smallish galaxies will fill 2/3rds of the frame so that should be fun soon when I image a couple of the smaller ones.

Looks very nice Greg. Have to say I'm envious. I better keep working for a few years and get myself a great mount.

Look forward to seeing some more images of nice galaxies in great detail.

Well, thats pretty good for a 1st light Greg. What were the exposure details? (or are they the telephone number ;-).

Yes I am looking forward to taking more.
Perhaps even tonight, it seems clear out there for now.

Greg.



Thanks Fred. It was a gorgeous night last night. I am not sure seeing was the best but very clear and dark.
LRGB 170 50 50 50 all subs 10 minutes 1x1.



Hehe, thanks Rob.



Thanks Frank. It is a very nice piece of equipment for sure.

I am looking forward to taking many images through it.

What a beauty Greg! That is quiet impressive for a first light!

Now for more drooling over that big scope and mount...oh and camera!
cheers Gary

Very nice image & equipment Greg.
The pic of the scope is a tad out of focus and needs a colour bal:lol:
I look forward to some more images from the CDK.

Thanks Gary.

I took my time getting used to the gear and checking it out.

Very very nice Greg. Pleased to hear its all coming together. Great effort for the gear's first trip up to "lightspeed"! :)
Sounds like a legendary setup.

Now that is a telescope worthy of the name! At 40kg on the mount, it must have taken a forklift or something to assemble it ...

The image of NGC 253 is very sweet too.

Envy strikes again ...

Thanks Rob. It wasn't too painful getting it all going either!



Thanks Marcus. I was a bit concerned with the initial images showing out of focus stars in the upper left but once I found out why and it fixed it I was happy.



Thanks John.

I am still getting used to it but I can see it will provide a great platform for lots of imaging.



Thanks RB. I took a long time to work out which scope to get. There's quite a bit of choice out there these days.

Good on you Greg for getting it all up and running - really nice first light image and the rig... well ... you can stop buying stuff for a while now. :P

Well Bravo Greg, that is an excellent NGC 253 and probably the best processing I have seen by you on a galaxy, a fantastic natural look and a perfect FOV for that galaxy. Perhaps the seeing wasn't optimal this time but when it is I can see some Johannes Schedler Namibian quality forthcoming :thumbsup:

Congratulations Greg excellent image exciting times ahead, impressive equipment :thumbsup: very envious I tried a run on NGC253 as well with my new camera but got freakishly got clouded out again as the first sub was starting grrr

Congrats Greg, great first light!
Looks like the little hiccup's sorted now.
Excellent round, sharp stars all the way from edge to edge.
Good run down on everything as well.

Man the 17" scope makes the ME look almost small:question:

Know what you mean with the weather, I think most of us are suffering from this, mmm so called La Nina effect. Hard to take with new gear just sitting waiting.. waiting...

Look forward to your next images with this fantastic setup (no doubt clear just in time for DLS:sadeyes:.

All the best
Rich

Nice work Greg. The detail is very sharp and I am sure you will improve with each image. I would be very happy to have this image, especially with the small Ha regions showing in the right hand edge of the galaxy.
