Re: CDK 14 on a Mach 2? #Mach2GTO

skester@...
 

I knew the CDK 14 on the Mach 2 was probably a stretch, which is why I asked the question here. On the other hand why would I 'over mount' a scope and have capacity I will never use?   I was already planning to go with a CDK 12.5 rather than the 14, so the question was a theoretical one.

These three elements are the building blocks of life and makes possible our existence here on our blue marble. They were cooked up, of course, inside a star that exploded as a Super Nova (or possibly not, I wasn't there to see it).


I cropped the Bubble itself into a closeup, double sized it and did some processing using Lucy-Richardson deconvolution in MaximDL to bring out the detail inside the Bubble:

Hi Bill,
I think you are talking about the QHY294M-Pro. Some of us have received one, started testing it and wiping away the flaws of youth. Personally I use Sharpcap-pro and with the latest drivers. There are 2 modes, an 11M and a 47M an AD Sample Depth of 14bits in 11M and 12Bits in 47M. A test on NGC7635-M52 with my 130GT shows an advantage in oversampling the 47M mode.
The sky is not too much with us at the moment to make many and QHY still has some progress to make on the drivers in the 47M mode in the opinion of some.

Thanks Woody!  I actually own PEMPRO from years back and was part of the beta so I have version 3 on a usb drive somewhere.  The issue is my camera, the qhy600, takes huge photos and slow download times so it is frustrating with any of these pieces of software that like to take faster exposures. What I could do, just to be done with it, is to install a camera like my ASI294 for the polar alignment and then switch back to my main camera when I am done.

Micheal,

 

Makes sense.  And I agree.  For a permanent installation, PEMPro would be sufficient.  And although I don’t know, it might have come bundled with your new mount.  And if not, a CCD Drift PA procedure is free and “should” only be necessary once or twice a year.  Here in So. Cal. we’ve got these things called earth quakes that can mess up permanent PA every now and then.

 

Have fun!

I am trying not to buy more stuff than I need.  An RAPAS is great but unless someone gives me one I have no intention of spending $500.00 on something I'll only use one time.   

For example I did not buy the hand controller.  The reason I am asking these questions is that I am trying to do this in my back yard just to play around and learn the software before I take it all out and put it up in my observatory 2 hours drive away.   Would be super handy to have a polemaster or RAPAS but it is not something I'll need more than once.

Re: CDK 14 on a Mach 2? #Mach2GTO

The Planewave version of the CDK 14 is 19" in diameter according to this http://pw-ecommerce.com/wp-content/uploads/2019/02/140101A-OVERALL-DIMENSIONS.pdf.
I do think this OTA is too much for the Mach2 if you are following the guidelines on the A-P site. I also think keeping the overall length within 50" would be a challenge.

Weight is not the issue, it's moment arm. I think you're stretching it with that size.

Based on the weight of the OTA + focuser/OAG/guider/FW of 55 lbs, outer diameter of 16" and a total length of 50", a CDK 14 would be well within the "Green" of the Mach 2 capacity chart in both RA and Dec.  However the recommendations I have seen on this forum often seem to be more conservative than the chart would suggest, so I thought I would as the experts directly.  Would a CDK14 be too much scope for a Mach 2?  I know most would recommend an 1100, but if the Mach 2 can handle it that would be my preference.
