  1. Well, after reading up on Nebulosity, Photoshop tweaking and the rest of it, I decided to try my hand at imaging last night. Set up the CPC800 and star aligned, piggy-backed my Canon 60D with Sigma 100mm f2.8 and managed a dozen 20s images at f4 of Arcturus and then got fogged out! Everything dripping wet. The whole point of the exercise, however was to try and get some frames that I could do something with in Nebulosity. Spent today stacking and tweaking with this result. Not the best image in the world but, hey, I enjoyed it!! Quite like the way a fogged lens causes the halo effect. Ray
  2. Hi I am currently researching purchasing the Pro Wedge for my CPC 800 to dabble in widefield photography, both prime focus and piggyback using an unmodified Canon 60D. Could some nice person please give me an idea of unguided exposure times I could expect using this set up (assuming I get the hang of polar aligning accurately). I am at a rural location (52° 33'N, 1° 3' E) with average light pollution (how do you measure it?) Thanks for any advice. Ray
  3. Thanks for the replies. I did insert the Barlow into the camera adaptor and then into the scope but could not get an image on the camera's Liveview screen. As I have a goto scope I have been slewing to my target and checking placement and focus through an eyepiece, then removing the eyepiece and replacing with the camera and attached Barlow. Would there be a significant shift of focus after swapping that stops me seeing an image on the camera's view screen? Ray
  4. Hi all. I took this shot of the moon last night with a Canon 500D attached to a Celestron CPC800. I am pleased with the result but would welcome any tips. My question is: is it feasible to insert a 2x Barlow between the camera and scope as you would with an eyepiece. I wanted to take close ups of various craters but could not get an image on the camera screen using Liveview. Thanks Ray
  5. I, too, was looking for a cover and found these http://www.screwfix.com/p/pop-up-garden-bag/10171?_requestid=115785 It covers my CPC800 with room to spare, is robust and folds up flat when not needed. They are on offer at the moment.
  6. I thank all you good people for your advice. I have read good things about the BST Explorers/Star Guiders, but I will research for a bit longer as the cloud doesn't seem to be shifting yet . . . Ray
  7. Hi all I recently bought myself a Celestron CPC 800 GPS XLT that comes with a 40mm Plossl, which is fine, but I would now like to get a set of eypieces matched to both me and the scope. I'll admit to 1. getting on a bit so the eyesight isn't 20/20; 2. a spectacle wearer; and 3. having a budget of £400. Any advice gratefully accepted. Ray
  8. A footnote to this post. I emailed Celestron support and had a swift reply: "A 3 mile variance is not going to make a big difference on star gazing. As long you are within 20 miles of the location that you are compared to the GPS it will not affect the telescopes ability to find the stars and planets."

    Hi all Fairly new to this hobby. Now in retirement I decided to treat myself to a scope and settled for the Celestron CPC 800. It arrived last week (thanks FLO, great service) and I have been waiting for a clear sky since. Last night I managed about an hour and a half and fumbling around trying to align the scope I happened upon Jupiter with Callisto, Ganymede, Io and Europa. WOW! what an amazing view! I'm well and truly hooked. Would you believe I couldn't find Aldebaran in the finderscope or the scope (stiff neck, dodgy knees, etc), but finding advice on this knowledgeable site is great and
  11. When you think of the distances between scope and target, does an inaccurate GPS location make too much difference?
  12. Could you please explain knobby . . . I am a newbie! Thanks
  13. Thanks guys After Googling I found out that the Compass ap on my iphone gives you long/lat so I will key it in manually. Oh, and Google Earth was right.
  14. Hi from a newbie I have just purchased a Celestron CPC800 and spent last night setting up outside and letting the scope find my GPS location. When it had finished the handset gave me the longitude/latitude coordinates which, when I put them in Google Earth, put the scope 2.5 miles due west of where Google Earth says my location is. Should I believe the handset or Google Earth?
