Hi guys and girls My qhy5l ii connects to phd2 but I dont see any image or able to click the cam controls next to brain as it's still grey in colour. If I start up ezplanet the camera works fine and I have a display on computer. st4 cable use or dont the phd2 tutorial says burn it but in vid it's still connected to his cam?
I'm after a bit of advice.. I tried guiding for the first time tonight with my QHY5v, connected to the HEQ5pro with an ST4 cable, guiding with a finder, and PhD. Soooooooo.... not too successful. I thought I was going well. I was getting a good guide star vey easily, took PhD Darks, all seemed good. Then, it started to go a bit pear shaped. When I'd done everything in PhD (connected camera, connected mount, selected guide star), I pushed the big PhD button. The W calibration started, and got to 61, and gave m the 'Star has not moved enough' message. So I increased the calibration step to 3000ms (then 10000ms just for fun) - Still nothing. Basically, the star doesn't visibly move at all. I've got the camera selected as ASCOM (late), and then choose the QHY5v in the second (ASCOM) box that appears. Then I choose 'on-camera' (I think that's what it's called), for the mount. I've got a straight-through 6-pin RJ12 to RJ12 lead for the QHY5v to mount ST4 guide port. Basically, the mount doesn't seem to move during the first bit of calibration (W), so it fails. Ive tried the manual movement in PhD. The only one that seems to do anything is 'North', which gives me a slight change in the whirring from the mount (subtle), and causes the guide star to move slightly on the video output. South, East and West don't seem to do anything, either in the way of mount whirring, or actual star movement. Any suggestions??? Is my ST4 cable correct (straight-through 6-pin RJ12 to RJ12) to go from a QHY5v to the HEQ5pro? By the way - I'm aligning and using the goto etc of my Synscan handset, and then using the ST4 port via PhD and the QHY5v to guide.
Hi Guys, I have an old C8-N with drives and a handset with an ST4 port. I'm using an Arduino to do small jobs around my setup like exposure control, electronic focusing, guiding and small GOTOs through the handset (large ones take too long). The first three work nicely, by my GOTO is all over the place and I've just realised that whether I'm looking toward the Eastern horizon or the Western one must mean that I need to invert my Dec movements. Is this the case? Is this the only effect of the meridian flip? The RA axis keeps on chugging (and I don't mean collecting for charity) in the same old direction, but Dec needs be inverted. Is there a proper name for these two modes, like "Western mode" and "Eastern mode", or before and after midnight? What else should I look out for? Thanks Steve.
Hi again, I've started on DSLR AP recently and I am doing it on an EQ3-2 mount with the RA+DEC motor upgrade and the enhanced handset with an ST-4 port. Im capturing using Backyard Nikon on my laptop and I would like to dither between light frames, but I am doing it unguided. Reading up on the Backyard... forums it seems BYN does indeed support unguided Dithering, so that should be possible. What is unclear to me is if I can do it with the handset: enhanced-dual-axis-dc-motor-drive-for-eq3-2 My next question is, how would i connect my laptop to the ST-4 guider port? Using something like this: zwo-usb-to-st4-guider-adapter ?? Hope you can help me out, been searching forums for a good while now, and no clear answer to be found.. Clear skies!
Hello. I have an unusual problem with my AZ-EQ6. I decided that I wanted to try pulse guiding rather than ST4, to get rid of a cable. I use MaxIm for all my controls, capture, guiding, pointing etc. and I use the EQMod ASCOM scope driver. My initial pulse guiding efforts worked ok, the mount would move and guide etc, no worries. I was not pleased with the pulse guiding results after some fluffing around so I moved back to ST4 and this seems to be where my issues started. Now, whether I choose ST4 or pulse guiding, my mount will no longer calibrate in the Y axis (Dec, I believe), or for that matter, guide. I have tried the move commands from inside MaxIm guide tab and X responds to a 10 pixel move but not Y. I tested with both PHD 1 & 2 with the same results. If it were a hardware issue, as in the mount has a Dec problem, would I be able unable to operate the mount with the hand controller or on screen motion buttons, both of which slew the mount fine? I could understand if the guide port were malfunctioning that ST4 would possibly have an issue but not when the mount slews as directed, so pulse guiding should work. Could it simply be that my EQMod driver has got confused and needs to be re-set, or am I looking down the barrel of sending my mount back to the dealer? Does any of this make sense? Thoughts and feedback most welcome.
