  1. Spectacular, as always!
  2. I love it! Would you mind sharing how you did these bits?
  3. That's a nice simple design. All you need now is a couple of limit switches and an ASCOM interface
  4. I take off the OTAs and cameras. If they want the heave a Mesu off the pier then they are welcome to it. The PC is bolted to the pier. I do have the obsy connected to the police-monitored burglar alarm as well.
  5. GOTO is not necessary. Tracking is though. The challenge is that to capture any sort of detail on something like Jupiter you will need a long focal length. Think in metres of focal length. At that length you'll find that the planet will drift off the chip very quickly, especially with a small sensor. Manual tracking might work but you might be better experimenting with Lunar imaging first.
  6. A beauty!
  7. 17th July Full Disc and Proms inverted by Stephen Jennette, on Flickr Goodbye to Active Region AR2665. The biggest, most active sunspot of 2017 to date slides around the Sun and off the disc. 6 pane mosaic. Lunt L60 pressure tuned with 50mm double-stacked etalon. PowerMate 2.5 ASI 174 mono camera. Stacked in Autostakkert 3. Sharpened in ImPPG and final processing in Photoshop
  8. Superb image. Top class!
  9. 8th July Disc and Proms Inverted by Stephen Jennette, on Flickr 6 Pane Mosaic. Lunt L60 pressure-tuned with double-stacked 50mm Etalon. PowerMate 2.5 and ASI 174 mono Camera Stacked in Autostakkert 3, stitched in Photoshop and sharpened in ImPPG. Final processing in Photoshop (separate files for the proms layered over the main disc. Both proms and disc inverted, sharpened and colourised). Thanks for looking.
  10. You'll know them once you see them. They really are a very unique sight and can't be mistaken for anything else.
  11. I think that that is an ordinary cirrus cloud uplit by the setting sun. Or maybe an iridescent cloud NLCs are really only seen after the sun has set.

  13. Try a blind solve to issue an initial Init by skewing to any random part of the sky and platesolving it. It sounds like AGO is platesolving the Astrobin image and issuing a slew, but the scope doesn't know where it is pointing at the start of the slew.
