  1. Good catch! Looks like a new AR coming into view. Probably AR2833.
  2. Ecuador, OK, I’ll try to download it to My iPhone and give it a trial. I ‘ll let you know how it goes.
  3. An optimum solution, but not mandatory. If you can image reasonably quickly between set-ups comparisons between the wavelengths would still be valid. I have an ED80 setup for Ha, a Genesis 4” for White Light and a Vixen Custom80 for CaK. These can be quickly interchanged on the HEQ5.
  4. If I went that route, I’d being using the existing GM8 stepper motors. on the Losmandy site there is very little info on these motors. I had assumed, probably incorrectly, that the OnStep software would interface with Cartes du Ciel in a similar manner to EQMod.
  5. The OnStep solution sounds very good, but when you visit the forum you quickly get lost in the “nerdy “ opportunities and alternatives. There doesn’t seem to be a OnStep solution available without getting involved in motor and mount parameters. I’d love to give it a go on an old Carton (TV systems) fitted with GM8 motors, but where do you start?????
  6. I use the Gert Neumann filter drawers. The body I have has T thread connections, and takes 2” and 1.25” slides.
  7. I've also just received a Vixen Custom 80M. Very good condition. Mine takes 1.25" eyepieces. I haven't managed to separate the dew shield, as mentioned, it seem to be fitted to the objective cell, which unscrews from the tube. I intend to use it for solar imaging, particularly with the CaK filter which needs a >f10 input beam. I've replaced the focuser with a 2" Crayford (needed for the CaK filter size) and used one of the original Vixen rings as a support for a focus motor ( which I find mandatory!) So far, the results are very promising.
  8. Another issue.... the zip and unzipped .pdf files are "located" in the "files" App, but the Acrobat App couldn't see or find them !!!!! The iPad is a PITA when it comes to files/ folders etc.
  9. Martin, Thanks for the comments. Adobe Acrobat is a paid App for the iPad but needs a current iPad Air 2 running at least IOS 13.3. It won’t install on my older iPad Air.....bumma.
  10. Hmmmm After all that, it doesn't seem to play well with an iPad. I can get one chart to open - APS101 1.pdf but that's it. No hyperlink etc. The instruction say to select a constellation to move the chart to the centre of that constellation -how? Similarly to select an object type????? Also "clicking the finder map moves the chart to the corresponding location" How do you "click" on an iPad???
  11. Update: Well using Dropbox can be made to work...with some pain!!! You also need an App on the iPad to accept files - "Documents" or "Files". I ended up with folders for scircum. zip and index.zip. Then used WinZip to unzip to scircum and index folders (couldn't seem to get it to unzip to any other option) In Documents, added a new folder Pretty Deep Maps, but found you can't select and move all the pdf files at once!!! About ten at a time....after a couple of hours (!!) I now have a first sample of the .pdf files and the Index.pdf files on the iPad. Next step is obvio
  12. There’s no way to “copy/paste” between the laptop and the iPad. The best I’ve achieved is to email myself a file and open it on the iPad.
  13. Martin, your sample zip downloaded ok. changed to Chrome on the iPad and it looked very promising. downloaded to about 900Mb of a 1.3Gb file, then up came the message “unable to download “ tried three times, with the same result. Running out of ideas.
