  1. So I went to reconfigure ASTROEQ but when I try to read the code in the Config program, it just hangs on "reading eeprom" and the times out after a while. Similar situation when I try to update firmware - it just cant make contact with the ASTROEQ. I've checked different com ports too... Anybody else get this??
  2. Ahah! So, I was missing a step - set the EQMod home position. The puzzle falls into place. Thanks!
  3. I don't have a handset. I'm running with PHD2 and an ASTROEQ box. What mode should I set this to? And what about unpark mode?
  4. I remember trying it and it didn't seem to make a difference, but I'll try this again.
  5. When I set my location correctly (Toowoomba, Australia), EQMod runs the RA axis in reverse (West to east). This happens whether using the slew commands or the tracking function. To get the RA to move correctly, I need to set my location to North and West (rather than South and East). I've screenshot the EQmod settings below, have I got some setting wrong?? (Port is not available because I just opened EQMod to capture the settings).
  6. OK, so I can see now how PHD2 would be able to get RELATIVE position from EQMod. But if I walk through the steps on a night of astro: 1. I set up the tripod with a rough polar alignment 2. I load PHD2/EQMod, which has my Lat and Long saved 2. I point roughly towards the meridian & equator, and do a calibration 3. I open the Drift alignment tool, and it tells me I am currently pointing XX RA and XX DEC. How did it work this out? At no point have I given any kind of information to PHD2 or EQMod about where I am pointed. I feel like I'm missing some crucial part of the set up, which I hope will be revealed by digging into the above question
  7. OK, so that just leaves my question of HOW does PHD2 come up with the values it reports in the Drift alignment tool for your current RA and DEC? Where is it getting that information?
  8. Sorry, yes we're interchanging a few terms here. My confusion summarised: How does PHD2 have any idea where the telescope is a) pointing, and b) physically located? It reports current RA and DEC position in the drift alignment tool. How does it come up with these numbers? And surely these positions are dependant on both where you are pointed and where you are located on the earth? Or am I mistaken on this? Also, you mention that Lat and Long need to be entered into EQMod - I have done this, however this made EQmod run sidereal tracking in reverse. I had to change my location from South to North to get the correct rotation.
  9. Thanks Terry, I was misunderstanding the role of calibration - am I correct in saying that it calibrates for the equipment, not location? But how does it get this information? Is it extrapolated from the calibration process? Otherwise there must be a GPS or something telling it where it is...
  10. So it sounds like the calibration process tells PHD2 where the mount is? And once I've calibrated, I shouldn't move manually using the clutches. How would I troubleshoot / fix the mount correctly reporting its position?
  11. Ok, so had a go tonight and it turns out a) that I do indeed need to be running the EQMod tracking while in PHD2, and b) the EQMod was tracking in the wrong direction. I can now get sensible results from calibration and the Guiding Assistant. Next questions are about drift alignment. I'm seeing "current scope pointing" numbers that don't make a lot of sense to me. When I go to adjust the Altitude, it wants me to slew to 0 DEC, and thinks I am at 90 DEC, but I am pointing at the Equator?? aside from that, 1. How does PHD2 'know' where I'm pointing? 2. Can I manually move my mount to where it is asking? As in, unlock the RA and DEC gears and rotate the mount head where I need it to. Or will that stuff it up?
  12. This was always my understanding - 58mm is the physical size of the magnification. After some more research I have come to realise that I think I need to engage sidereal tracking on EQMod, after which I should go through the guiding steps on PHD2. Seems like a basic thing to miss, but believe it or not this is not mentioned in any tutorials! I'll give this a try when I next get a chance.
  13. Calibration at Dec 0 makes sense. Does the RA position matter much? Where do I enter the guide rate setting??
  14. I am using a Helios M44-2 for my guidescope. It says 58mm on the lens, which is what I enter into PHD2. Hopefully the Russians report their lenses correctly... I will try clearing the backlash, although the Guiding Assistant says my backlash is 'low'. I'll try the starcross test too. Once I've selected a guide star & calibrated, do I just press 'guide' in PHD2 and it should work? Is there anything I should select on the EQMod window, or are these buttons unrelated to guiding??
  15. If i understand this right, you're saying I should have the guide scope pointed just about straight up for good calibration? I had been calibrating at 0 Dec but down low near the horizon. I have been working through the best practices but obviously got stuck at the calibration step. They seem to suggest I can do a rough polar alignment, calibrate the scope, then do a good drift alignment after that? Is that the right order? I'm guessing I would need to recalibrate after drift alignment.
