No need to go "some more" beyond finger tight. I have actually forgotten to tighten the clutches at all and not noticed - slewing and guiding still worked.

No problem. In hindsight you can probably get away with 2-18, 1-10, 1-5. Notice on my photo how the 10 is almost flush with the 18s up top. The 10 is in the middle when I have my imaging train on

I run a C14 on my AP1100, which is close to 55 lb with accessories. I use 3 of the larger diameter weights and it’s just about perfect with the weights at the top of the shaft. The counterweights

Hey Sébastien - just one thing I can comment on: >>>If so, I was wondering if I should ONLY tick the "Enable Dec Arc Tracking" checkbox or if I do also need to tick the "Enable Tracking Correction"

Dec arc tracking is for doing unguided imaging on one object along the track. It really isn't intended for pointing, so it is of limited use for that. If you want both, you need to make a full sky

Hello Howard, I'm also trying to learn the ropes of the new Dec Arc Tracking feature for portable use (with a new model each night). Please keep in mind I'm totally new at modeling in general. At this

Eric, thanks for the input! I’ve got that same honking hunk of optical magic!! So maybe; 3-18 1-10 1-5 Sent from Smallbiz Yahoo Mail for iPhone

I’m assuming your Mach1 has the upgraded shaft since the previous owner is using those CW on the 1100. Make sure it’s the 1.875” shaft before ordering. I don’t think the 30lb will fit as the

In my experience if your OTA+imaging train weighs 55lbs you need more than this since it is recommended to keep the largest CWs close to the top to reduce moment arm swings and then fine balance with

Thank you Howard, Will try this next time, I’ll let you know. Andrea

Excellent, thank you all for the responses!! Next question is that I need to buy counterweights as the previous owner is using on his 1100. My current set up weighs about 40lbs and new scope which I

Well , more like delegated to the light work:)

We recommend both the FTDI dongles and the Keyspan by Tripp-Lite. Both have excellent drivers. We now sell the FTDI USB to Serial converter because we use the FTDI chipset in the GTOCP4/5. The same

Michael, ownership of your new AP mount means your Losmandy & iOptron mounts will now become doorstops or paperweights 😃 Fernando

Hi Andrea, for portable setups, the APCC Dec Arc feature is amazing! It is perfect for your situation. I would definitely run 3 arcs if you can spare the time – one right on the target

I agree the USB->serial converter is all you need to be happy with the CP3. The FTDI chipset has been the standard for about 20 years, and you can download drivers direct from them. The Prolific

Hi, the new functionality is now more mature and I assume some of you have some good data to share. I usually shoot one subject per night. Given the declination, what is the best combination of

Wow! You can!? That's amazing. :-) I'll send an email to you to set that up. Thank you so much!

Yes that’s a lot of weight to think about. Maybe put some weight on first before you load the OTA? I’ll defer to the board here but off the cuff yes I personally loaded the OTA from the Side as

We got here about 10 days ago. And after hard day of setting up the trailer, my wife and I were sitting outside just before sunset when we saw a series of bright flashes about 160° south of us. I
