Celestron ultima duo and camera questions

Recommended Posts

Hi astropeeps 

 

Can anyone explain why the view through a 21mm celestron ultima duo eyepiece frames the moon perfectly, but when I attach the camera it acts more like a 18mm eyepiece and a third of the moon is out of frame? Do I need an extender of some sort or a better camera? I have a LUMIX G7, micro 4/3 mount.

 

Cheers

      Hi All,
      If anyone is looking for a great telescope, I'm selling my NexStar 8SE. It's in great condition, Optics are immaculate and there is only some signs of use on the dovetail bar and the black rim that has faded a bit on one side. The reason that I'm selling is that I'm looking to upgrade.
      I had some amazing views of planets and DSO through this scope.... it really is a performer in quite a compact package.
      This scope was on a CGEM most of it life so the NexStar Alt-Az mount was hardly used.
      I prefer to have this scope local pickup or I'm happy to deliver and even give a tutorial and demonstration of how to use it.. for that reason I'm targeting a buyer around Sydney Australia.
      The price I'm asking is $1650AUD.
       
      Clear Skies.

      Hi all,
       
      After updating my legacy HC to the 99.22 (I had to, because of the GPS rollover issue) and the MC to the 5.23 firmwares (siply because it was there, and I've got greedy), both acquired via Teamcelestron, my CPC was operating normally until, all of the sudden, its altitude motor stopped working. I've uploaded a video at youtube showing what happens:
       
      https://youtu.be/p2cHJkPt9Vc
       
      As you can see, I don't get any error message in my HC but, if I try to move the scope in altitude, nothing happens (no movement, no motor noises, nothing). When I release the clutch and move the scope manually in altitude, it does move but has a weird noise by the same place where previously it used to make a snap one, which I already reported to celestron tech support once, and even made a video that I also uploaded to youtube:

      I've already seeked help from Celestron Tech support (and the folks at Cloudy Nights) but any help from you would be very much appreciated. Best regards,

      So, i have settled between 2 eyepieces for my scopes.
      The explore scientific 6,5 mm 52degree 
       
      and the Skywatcher UWA Planetary 6mm
       
      I have read that the explore scientific gives better contrast and views.
      The explore scientific will give me 184x and barlowed 369x So should i trade less magnification for more detail?
