Have never gotten any kind of response. Someone please respond. Thank you.

Hi Robin, I think this is a bug, but if I am misunderstanding something please forgive me. I have an Orion EQ-G mount (which I think is equivalent to a Skywatcher HEQ5 mount). What I am encountering is this: 1) I setup the telescope and power on. 2) Perform a "Good" polar alignment and set...

Hi Robin, I have been playing around with Sharpcap's lunar and solar mosaic options for a while. They are a lot of fun and very useful when your optics don't allow for a full view of the sun or moon. It seems like it would be possible to extend these routines to deep sky targets. The user would simp...

Hi Robin, I've been reading a bit about binning lately and it seems that there may be ways to calculate the optimal binning for a particular camera for a given set of sky conditions in order to give the best combination of sensitivity and sharpness. Is this something that could be implemented into S...

Hi Robin, Yes, the Platesolve3 tested correctly so all seems to be well there. My question then is why the other plate solvers seem to work correctly. I thought that Platesolve3 was supposed to be very robust in its capabilities. I had high hopes for it but now I have an uneasy feeling about using i...

Hi Robin, I was playing around with the different plate solving routines using the Deep Sky Test Camera. What I found was that the Ansvr routine seemed to work correctly in that the Deep Sky Image Annotation correctly identified the Orion nebula. However, when I used the Platesolve3 routine the loca...

Ok. Thanks all. I guess I have a bit of testing to do.

Best, Bill

The MPCC specs say it is good down to f/3.5 so I'm wondering if I adjust the spacing on the reducer so that it gives me a 0.7X reduction whether that would be the thing to do. A 0.7X makes the scope approximately f/3.5. Just wondering. Thanks.

Best, Bill

Hello Jean-Francois, Thanks for your response. You have hit on the essence of the problem. Using the MPCC alone gives great images with no coma out to the corners of the image at least with my ASI1600. The reducer gives me the wider field that I like, but at the expense of having a good deal of coma...

So this is a question for all you optics gurus out there. I have an f/4.9, 8" Newtonian reflector, a Baader Multipurpose Coma Corrector (MPCC), an Apertura 2", 0.5X Focal Reducer, a ZWO EFW, and a ZWO ASI1600MM camera. My question pertains to whether there any way to make these different o...
