  1. Hi You might need to service the Crayford and try and see why it's slipping. I didn't have that problem with mine but later on I did attach a SW motorfocuser and they are very good at holding the focus and make it easy to make very small focus adjustments with changing conditions -plus you don't need to use the lock screw Louise
  2. Hi Two things: 1 - the cam won't be in focus. You'll have to adjust it manually and it will be quite critical. 2. You will have a very small fov and you will have to adjust the mount to be on target within that small fov. It's worth putting the scope and camera dimensions into a fov calculator like 12dstring. Louise
  3. If you use ST4 then make sure the guide cam is set to 8 bit - it uses the other 4 for mount control. You set the bit depth in phd2 using the tool button next to the camera connect button. Louise
  4. The phd2 manual controls only cause tiny movements. Test the guide output by using it for real on a guide star. I wasn't aware there was a new version/handset. I take it you can slew the mount ok via whatever planetarium software you're using? Louise
  5. Hi You should just connect your guide cam via usb to your computer and use PHD2. Connect the handset to usb using a usb-serial cable. Make sure you have Ascom installed and the correct Celestron driver. It should all work smoothly :). Louise
  6. Hi Alacant You can get a set of secondary thumbscrews from TS Sorry, don't know screw size for the focusser. Louise
  7. Hi Just wondered if you might have tried longer exposures (~15-30sec) of dso's with the Hypercam 178? Thanks Louise
  8. DSLRs aren't sensitive enough really though I might try Astrotoaster one day. Louise
  9. Hiya Have you used one?
  10. Hi all I have been using a qhy minicam5s mono (a cooled qhy5l-ii) which is pretty sensitive and is ok. It's attached to an 80mm TS Apo. I'd quite like to do some video AP with the 115mm Apo but I'd probably want something bigger - maybe 4-6MP (so definitely not a Lodestar or Ultrastar!). Maybe colour, though mono is obviously more sensitive. Maybe cooled but I'm not sure how essential cooling is with short exposures. Any thoughts? Louise
  11. I think I'm probably a bit of an oddball since I've never done any visual. After attending an intro to astronomy course at a local uni it inspired me to go straight into AP! Not that there was any AP or even any stunning pictures in the course. I just got a bee in my bonnet and went for it. First just with a 1100d and 300mm zoom lens, and rapidly progressed from there! It was actually my first dslr and my first use of a long lens. But I have a technical/scientific/computer background so the technicalities of AP came fairly easy to me. However, I'm stuck in a second-floor flat in a light polluted city that has few clear nights. I've been losing my dso AP mojo of late - largely because of the dismal weather but also because of the limitations imposed by my situation. I also don't think I'll be able to find the time if my academic ambitions are realised. I've had a busy academic year this last 8 months and exams are now imminent! I might still do occasional dso AP plus some stellar spectroscopy. Another possibility is to do some video astronomy (probably with the minicam5s but might get a colour gpcam or similar). It's 'quick and dirty' AP but still quite rewarding, I think - sort of instant gratification! I think if I continue with the studies then video AP is probably all I'll have time for! Louise
  12. Hi I wouldn't bother with star alignment and just do platesolving instead. I use APT/Astrotortilla but APT also supports it via another package. The marks on your subs are likely dust on the camera sensor. Stacking with flat frames will get rid of them. Louise
  13. Hi I would check balance first and in all three axes (RA, DEC and vertical). Get it perfect then adjust the counterbalance weight to make the mount slightly east heavy. Louise
  14. Moving is just a dream - won't ever happen
  15. Awesome!
