  1. After two deluding years using SkyWatcher AZ EQ6 to handle a Meade 7” ED refractor, I got back to my previous mount, the manual Losmandy G11. I had to have maintenance performed by a specialized firm, and also to inspect the RA and Dec worms bearing screws and Oldham joints most accurately by myself. At last, after a good tweak and regreasing I reliably got round star images in my frames, without guiding, up to 60 s exposure. I don’t care with longer exposures since I was forced to choose capture of many short shots, useful to increase the combined image S/N ratio, after my once dark sky site was ruined by light pollution. Still, a tiny RA drift still remains, as visible after capturing a handful of frames. I use the QHYCCD Polemaster for polar alignment, and I move the mount manually when accomplishing rotations of the RA axis forward and backward. The instruction manual strongly recommends not to do this by hand as it requires clutches release, possibly generating axis unset. Since Losmandy clutches do not need to be released for manual axis motion, I disregarded this advice. As expected, the reference star of Polemaster neatly follows the green circle when I put back the scope to home position. When I align by Polemaster the mount already aligned by the drift method I find exact coincidence of the two methods, not as time consumption, of course! PHD2 evaluation of alignement precision rates 3 arcsec distance of the true NCP. My former expectance with Polemaster was better precision than with drift align in much less time … well, I get similar precision in much less time. Did I attain the best? Is this residual imprecision I get with Polemaster to be attributed to inherent matters of the mount? Is there any optimization for increasing the precision with Polemaster? Can poor mount leveling affect Polemaster performance? What about imperfect RA and Dec balance? Thank you for advice and suggestions. Clear skies, Cesco
  2. Hi I am looking for the QHY Polemaster for doing polar alignment. If you have one and no longer need it please send me a message and I will get back. Thanks and Regards Yogesh
  3. Hello. I am considering getting a QHY Polemaster for my AZ-EQ5 mount. Has any one used this combination and did it work well? Also I have heard that the Polemaster can wash out if light pollution is present, how much of a problem is this? The light pollution is not bad but I have to look over the house to see Polaris and I wonder could overspillfrom it wash out the Polemaster. I would suppose this to in part depend on how wide the Polemasters' field of view is. Any observations and advice would be welcome. Jim
  4. Im completely rubbish at polar alignment so I got myself a polemaster to aid and speed up the process. I know the manual is pants but I have seen loads of videos on the tube, and I have been able to follow what's going on, and managed to align the scope. When I tried to verify the alignment with Phd2, a huge alignment error is shown (-104). I've also found other problems like non orthogonal axes when calibrating PhD. Has anyone any ideas on solving these issues? God I wish this hobby was less frustrating
  5. Hi So this thread will cover in fact PoleMaster, Astrotrac and GiroMini because this is my setup.I bought the PM (PoleMaster) since the Astrotrac has a fail polar scope (no matter how you fiddle about it), and of course the dedicated adapter to mount PM on the AT (Astrotrac) arm. PM is a real joy to use, but somehow I suspect the AT polar arm has some "issues", so I bought another PM adapter for AZEQ5 and mount it right on the GM (GiroMini).It was based on another suggestion I made to a fellow astronomer, but nobody did it. Long story short, below the new adapter in place. I am certain this is as close to the rotation axis as it can be. The plan is to replace those M3 screws with M3 thumb screws in the future for easy setup and not to have the PM there when I don't use it. I will post more pictures "in the wild" and on site results ,but now the clouds are here because my new ES 82° eyepieces also arrived
  6. Hello, On my Surface Pro 4 running Win 10, when I start PoleMaster I get the same warning message from Windows as I would if I were installing it. Anyone else has similar experience? Is this normal? Thanks
  7. Hi This is about my adventures with my Polemaster and GIRO MINI It is about mounts but also about DIY. More info here. The final "product".
  8. Hi there folks, at the moment I'm primarily a traditional, through the eyepiece observer, however I'm putting together a list of components/software that I will need going forward as I venture into the realm of EAA. Primary consideration for my EAA platform is that it be easily transportable with as small an on-site footprint as possible. My thought is that I want to be able to control everything remotely over WiFi, I have an abhorrence for spaghetti cabling, so want to be able to keep this situation down to a minimum. To this end I have put together a list of components which I think will facilitate the sort of observing platform that I am aiming for: Item 1 - Polemaster from QHY and associated control software. I have both Alt-Az and Equatorial setups, however I see the equatorial as being the primary mount for EAA, hence the investment in Polemaster. The EQ is a Vixen SXW and the Alt-Az and Altair Astro Sabre. Item 2 - Small footprint CCD/CMOS Astro-Camera (I'm thinking along the lines of the SX Ultrastar), and associate control software. Item 3 - Guide camera (Although this may not be an immediate requirement bearing in mind my primary goal is near real-time observing rather than traditional CCD astro-photography). Thinking perhaps the Altair Astro GPCAM, or perhaps an older SX Lodestar. Associated software perhaps PHD2, what alternatives are there? Item 4 - Computer stick or very small footprint PC capable of being fixed to either the mount or OTA, without seriously adverse weight impact. The device needs to have integrated WiFi capability and the ability to interface to guide camera, primary camera and Polemaster. Needs to be run from 12V DC supply. Item 5 - Apple iPad (already acquired). Item 4 poses the question, does such a device exists that will enable simultaneous connectivity to all three devices? Immediately people may think of alternatives such as the Mallincam line of products, Revolution Imager etc... however I want to try and steer clear of the older analogue technology. Is the suggested approach realistic, in getting me to where I want to be, if not, are there alternative ways of achieving the same goal? Would appreciate the forum’s thoughts, and in particular any insight from fellow forum members who may have taken a similar approach. Kind Regards Paul J.
  9. Hi there, has anybody ever used the Polemaster on a Vixen SXW, I am thinking of investing in one, fed up bending over my polar scope. Kind Regards Paul J.
  10. Hi All, I'm trying to balance my AZ-EQ5 as perfectly as I can, all was going well (all 3 axes) until I added the Polemaster. As this is off-axis it applies torque to the RA causing the axis to rotate until the Polemaster is hanging at the lowest point. I need to couterbalance this, any ideas how? or, Do I need to counterbalance this? Am I being too picky? I have considered taking the arm off and gluing the Polemaster onto the on-axis point of the top cover, but again, is this overkill? Thanks, Neil.
  11. Setting up all the software on my win10 laptop and getting things to talk to one another is a nightmare. I'm starting a new thread, so I can post all the problems I am having, one at a time, so issues don't get confused. This will also hopefully help anyone coming to similar situations later, as the problems and answers will not be interlaced. First issue: APT does not detect ZWO camera. I have got the camera (ZWO) drivers installed and sharpcap can see it and will connect to it properly. However, when I try to connect the camera in APT, the only CCD options it gives me are SBIG (which it isn't), QSI (which it isn't) and ASCOM. Now it shouldn't need to use an ascom driver, because the proper driver is installed, but I give it a go anyway, and this just offers me 2 simulators and 3 QHY cameras (I have one qhy driver installed for the guidecam .... I'll get to that later!). I have disconnected both the filterwheel and guide camera from the camera hub, so they cannot be interefering with the process. I am at a total loss ... any suggestions? Thanks.
  12. Thought I'd post this here as it may help others with AP900 mounts and Polemaster i made my own adapter to screw into the Polarscope peek hole in the Dec axis casting (my first proper piece of work since getting a lathe - a purchase driven from my astronomy habit and never seeming to have the right adapter despite having two boxes of various adapters!). only used PoleMaster once so far, velcroed and tie strapped to my mount, but it worked great, and this adapter should improve the mounting somewhat!
  13. I was discussing with a fellow stargazer, during a cloud induced intermission over a few drams the other evening, the merits of the QHY Polemaster and an interesting question popped up. Would it be in QHY's interest to collaborate with a mount vendor and package their Polemaster product with that vendor's mounts? Their is a key argument against such a move that being that QHY could probably make more selling individual units to the market than via such a collaborative effort. Would be interested to hear fellow forum members views on this topic. Kind Regards Paul.
  14. The QHYCCD PoleMaster polar alignment system is generating a lot of interest and it certainly seems to work very well indeed. The process is very simple and following the on-screen prompts makes it quite easy to achieve a very good polar alignment but the instruction manual does come in for a lot of criticism. Sooooooo ....... I''m sure you can guess what's coming ....... My own version of the Polemaster manual - enjoy! PoleMaster User Manual English UK Northern Hemisphere.pdf
