    Eq5/Bresser messier eq5

    You can, and rely on the hand controller for most other things. Personally, I prefer to be able to plug in my laptop/pc and use *Stellarium to control the mount and do platesolving etc. But it's not essential to be able to do that. You would still need a laptop/computer to control a ccd/cooled imaging camera. Louise edit: * not to forget Eqmod too!

    I don't think the Exos-2 goto has a computer interface.?

    target framing assist which software

    The lightvortex tutorial is a good place to start for AT http://www.lightvortexastronomy.com/tutorial-setting-up-and-using-astrotortilla-for-plate-solving.html

    target framing assist which software

    Hi I use APT which supports Pointcraft/Platesolve2, though I've only ever used it with Astrotortilla (AT). Both Platesolve2 and AT are external programs for blind platesolving. AT centres targets a treat (usually within about 10-15 secs). Platesolving saves having to do star alignments / making pointing models. Louise

    Too good to be true?

    Looks like a fake ad - Adam and Eesa only sell kids clothes?

    The EQ3 DSO Challenge

    I just happened to have a 'spare' heq5 tripod as I put the heq5 mount on a pedestal. Otherwise I might have made do with the supplied eq3 pro aluminium tripod though it seemed a bit too lightweight to me. Louise

    The EQ3 DSO Challenge

    Hmm… there are lots of factors that determine fwhm. Clearly, the heq5 is bigger, stronger, better and has better stepper motors. The eq3 has a low payload - ~5kg, I think, for imaging. But, certainly, with an heq5 tripod it seems to perform quite well. I probably wouldn't use it with more than about 500mm focal length. But it's portable, even with the heq5 tripod. The eq5 is the mount in between the two in terms of payload. It all depends what your looking for and how you're going to use it. Louise

    The EQ3 DSO Challenge

    The heq5 is superior to the eq3 pro in every way - except price and portability! The eq3 pro on an heq5 tripod seems quite good Louise
  9. Hi again The calculate function is very simple! You just enter the data for your guide scope and guide cam plus a few other bits. The guide speed is from the slide controls in eqmod, that I mentioned before. Generally you'll have that set to .8 or .9. Number of steps - about 15 should do. The dec is from where your pointing - I think phd2 picks that up automatically, as well as the eqmod settings. I think, generally, pointing at a dec of about 30 deg is good. Anyway, it just returns a value in ms that it uses to step time the calibration ie the value in the box next to the calculate button. The actual calibration should only take about 5 mins. It can have trouble getting back to it's calibration start position if you have a lot of backlash. It sounds like your power died or you hit track limits? (Again something you can set in eqmod). Hth Louise ps there is a useful eqmod pdf here
  10. Hi Neil Are you calibrating ok? Have you set your guidescope focal length in PHD2 and used the calculate to get a calibration step size? Also, in eqmod there are ra and dec guide speed controls. Hth Louise
  11. The calibration just measures the relationship between the guide cam and the mount, so that shouldn't change. Louise
  12. As I recall you have to run the guiding assistant for about five minutes and I think there is a checkbox to check backlash? (Though maybe it does it by default when you tell the guiding assistant to halt). If your setup is fixed, you shouldn't need to redo the polar alignment unless you change something. It's a bit catch 22 in that you need a good PA in order to do a calibration. But you have to do a calibration first so it's an iterative procedure. But with everything permanently setup you shouldn't have to do a calibration and PA each time. Still, as I said, the avx does have DEC backlash and there isn't much you can do about it. Louise
  13. You can check the basic setup indoors during the day to make sure you're ready to go, That's what I'd do. The avx does have a reputation for having a lot of DEC backlash (my own avx is no exception!). It can show up during the PHD2 calibration sequence. You may be able to ameliorate it by guiding in one direction. I think Ascom autosaves its settings. Louise
  14. Hi Ok - an oag can complicate focussing a bit but if you've had the zwo in focus before, that's good. If the focus hasn't moved - even better! Is that a carbon fibre sct? An aluminium one will likely be on the heavy side for imaging on the avx but you might get away with it. Which planetarium program are you using? I use Stellarium with StellariumScope - works for me . The Celestron driver should just work but you may have to do some setup in Ascom. I can't remember now - you may have to run the Ascom diagnostic utility. Louise
