PoleMaster DIY perfect align

Recommended Posts

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 :)

This is how it looks in RL (ignore the mess... I was doing some tests/ reorganising my backpack)

I will post how this works as soon as the rain stops :)

UPDATE take 2.

I realized it is too much hassle with an imbus (how we call torx) in the dark , and that aluminum holes are not very resilient against a lot of (ab)useing with strew/unscrew every time.

So I planed to put a permanent headless screw in on which I will use a nut. The problem was my goles were too close to the RA lever and was blocking it.

Time to another set of holes... 1 hour later was done.

Btw, I also upgraded my DEC and RA screw to a more modern look :).

Unplanned it helped a lot with my mod.

I wanted this too look "stock" and professional made, not something made up in a haste to a solution.

The wait time for the parts (1 month for headless crews, RA & DEC upgrade, red nuts) was worth it (from alliexpress china).

 

1. Barely clearance between the PM red nut and the blue RA screw (hence the second attempt and drills).

The original screws of the AZEQ5 plate are now screwed in the old holes... a nice place to keep them handy, just in case..

2. Told you my upgraded blue RA screw gave me a nice surprise... clearance to my fingers to access the red nut easily.

3. One red nut out, the headless screw revealed.

4. Oops, no clearance to take out the PM adapter... wait...

5. .. voila, kudos for the upgraded RA nut and its clearance.

6. Both headless screws revealed. Notice they are at the very edge of the MiniGiro.

7. Ready for the PM to be put back in the case... or ready for a session of visual stargazing (no polar align needed).

You may see that the DEC got a new blue lever too :)

An easy DIY mod to ensure the PM is right in the axis, using another PM official adapter and couple of parts (about 20$ total) which also looks nice to look at.

Feel free to ask any questions about parts or the procedure.

      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.

      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

      For those struggling to collimate there Astrotrac Polarscope (as I was), check the tube housed in the main body of the scope for flex and ensure it is the right way round.
      today I removed the tube and swapped it around, this made ALL the difference, collimation was a breeze after this.
      I have already swapped out the grub screws for thumb screws and remember to make tiny adjustments each time.

      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.

      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
