Randy, yesterday I bought a used Mallincam Xtreme with Class 0 chip.

I am very much looking forward to it!

Heinz, That's great news. The Class 0 chip will give you less warm pixels. It's a great camera. Hopefully, you can get some good observing in without having to go too far. It makes it sooo much easier, the more convenient you can make it. You wil have it up and running in no time.

Hello Paul

Do you expect a larger brother to the ZEQ25 to be released during the next few months?
I still like the concept, but theZEQ25 is in my experience too unstable for my CN-212, not to mention the Mewlon250. But a stronger version is on my wish list.

Best regards
heinz




I expect iOptron to have some interesting news at the Arizona Astronomy convention in Tucson on Nov the 16th.

I will be disappointed if they don't once again set the bar a couple of notches higher with their innovative designs.

Guess we'll both have to 'stay tuned'....?

Clear skies...Paul

I just recieved my Z mount, and haven't had a chance to use it yet. I ordered it in large part because of the reports in this threat, but wow, the thread has really grown. I'm reading it, buts it's hard to take it all in. I don't suppose someone would care to condense the important points for those of us late to the party?

I do seem to have some play, and I noted that one of my tension screws had a chip off it, thanks

OK, so my first encounter with Ioptron support was great, rapid response on a weekend and good info.

I had thought I had play in the RA box, but not after evaluating it with their instructions, and now that I understand how the box lifts to release excess force it seems fine.

Also, I had a corner sheared off the bottom of the RA tension screw. Since the DEC is square, I assumed this was a problem. According to support, they filed these down for some clearance issuses and mine just needed a little dressing. He said they recommended early buyers to DIY (about 2mm). I would add that it's a soft metal, and will file down quickly, I almost took too much off.

Can you elaborate some more on this sheared off corner or post a pic or two...I don't quite understand what you are trying to share with us?

Thanks

John

Same here John. Since the tensioning screw is round, it can't have a corner? I think what he meant to say is that it had a burr or gouge at the bottom of the tensioning screw thread?

Just assuming...Paul

Here ya go. Since my DEC screw doesn't have that, and I thought I had RA play, it seemed like a problem.

Is the optional 2 inch leg tripod worth the extra $100?

Personally, I don't think so. I haven't had any trouble with the 1.5" legs but I have the tripod set to almost the lowest position. If you have any question about its value, you should get it to start with as the cost is about $200 if you order one later.

Mike, I can't find tripod heights listed on iOptron's website. Could you give me an idea what low and high are?
I'll be doing visual and imaging.

I can measure it tomorrow but the tripod and mount are just under 35". It works great for AP. With a refractor or SCT with a diagonal it is ok except near the zenith. Then it is a bit low! I tried it with a 6" f/8 Newtonian and that height works out great. Let me know if you need an exact height.

I had to search back through this thread, but I found the tripod info you need:

Quote:

the 1.5 inch tripod height is 42" to the bottom of the mount base.

The 2.0 inch tripod height is 52" to the bottom of the mount base.

The 2.0 inch tripod will give you an additional 10 inches of useable height and a very stable platform, but it will add 6 pounds to the tripod weight (17 lbs vs 11 lbs).



Hope that helps...Paul

Thanks for the information Paul and Mike. Looks like the 1 1/2" legs will work for me.

As far as your RA-? If that means reversing RA, it's not going to happen, because RA is not reversible in guiding.



Quote:

RA- at 1X guide speed simply stops the RA motor. So of course it won't produce any sound.




That makes absolutely sense to me and it's what I thought too. My concern started when I heard the buzz noise coming from the Heq5 upon pushing that very same RA- button.
But I guess this is something I shouldn't worry about any longer




Bringing back this old issue because instead I'm afraid I'll have to take care of it.
When trying to calibrate the autoguide setup, linguider complains that it can't bring the guide star back to the starting position and that there might be some problems with the mount.
I tested the st4 port manually with a short piece of copper wire and it confirmed that connecting pins 2 (common) and 3 (ra-) doesn't produce any effect on the mount, whereas it does with the other pins 4-5-6.
This sounds compatible with linguider's complaints, what do you think?
I've already emailed ioptron support, let's see what happens.

Ciao,
Piero

Hi Piero,

In Linguider, there is the manual drive control. Select your drive type (QHY5 for example) and connect the guiding cable to the mount. Set the guiding rate in ZEQ25 to the maximum. When you press and hold the direction key, you will see the RA or DEC change. If there is no movement, it can be the problem of:
1) autoguider
2) cable
3) mount

It is better to start from the cable. You may try another cable.

Anat

Thanks Anat, the manual guiding in linguider is exactly what I've tried.
I've also tried two more cables which work perfectly with my Smarteq mount, but nothing changed.
Just for a confirmation, does your ZEQ25 ra motor buzz when you press the manual ra- button in linguider?

Thanks and ciao.
Piero

Piero,

Yes. If you set the guiding rate = 1.0x and press RA-, the motor will stop.

Anat
