Celestron Focal Reducer - #94175 - Celestron say it's not compatible with Edge optics but I have found that not to be the caseBy StarGazingSiouxsie
I bought a Celestron focal reducer / corrector lens part #94175 for my non Edge CPC1100. Celestron say - in bold type no less - that this reducer is not compatible with Edge HD optics. The cost of the dedicated reducer for the Edge optics ( #94242 ) is ~ $200 more than the non Edge version
Out of curiousity, and to make sure what Celestron say was correct, I tried the non Edge focal reducer part number #94175 on my 8" Edge telescope - and it works just fine. The field of view is expanded as it should be and the clarity to the edge of the view is as clear as when not using the reducer. IE vignetting is minimal / non existent
Has anyone else found this to be true with their Edge and non Edge telescopes? This is significant; the price difference is about $200 between the two reducers and, in my case, the non Edge reducer gives me altitude clearance on the bottom of my Evolution mount whereas using a dedicated Edge reducer ( #94242) would not.
So if you're in a similar to me, try the non Edge reducer first before spending an extra $200.
Hi to everyone,
I'm new in the world of the telescope and as my first telescope I bought an used Skywatcher 70/700 with supatrak mount and I hope that someone can help to understand the equipment I'll need to connect (cable, bluetooth or wi-fi add) my telescope mount to a Mac and control it by software like EQMac or Stellarium.

I am making a controller for my old celestron cg4 mount I have its original motor attached but don't know whether its bi-polar or a uni- polar. Can someone plz tell me ?.
And i also need help in programming an aurdino for it.
Thanks in advance
I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.
