I'll have to regrease my mount and let you know the difference. I've never been too concerned with a few seconds of the sound, it always seem to end quickly under the temps where I am likely to use th

I have used my AP1200 on at least a hundred nights between -10F and 0F for hours each session. The only thing I've ever noticed is my mount motors start to squeal and warble during the first few slews

I used a heavy 175 f/8 on an AP900 and it was excellent !!

gmail sent that before I was finished : ( I think the best thing possible would be to run only DC power 12V over these: http://www.polarwire.com/ourwire.html Then, on the scope, convert to other volta

Great information, Barry. Thanks. Most clearn nights here are -15F to 5F (-26C to -15C) most cables are a royal PITA at these temperatures. I think the best thing possible would be to run only DC powe

Is it getting cold there? I was using my 1200GTO at -15F the other day and it was singing like a warbler song bird.

Back in 2008 before I was using a computer for imaging, I have used the keypad to re-sync the position of the object to the center of my desired framing. Then when you goto the object, it is back to y

From the manual: Because of flexure, polar misalignment, refraction, and other effects, the apparent tracking rate of stars and deep sky objects in the sky is not exactly equal to the sidereal rate. T

Wow! Congratulations AP, this is huge!

Ron > absent a workable guiding system with active PID tuning Is there software right now that uses PID to refine the guiding settings whilst guiding? (Or to refine guiding settings by studying logs?)

I've also taken the power supply to gatherings in a large padded nylon fabric rectangular case, like a big camera bag. I run the 120V extension cord into the bag where the 15V converter power cord plu

I've had mine outside in a roll-off observatory for 7 years in -40F to 85F temps. It's worked flawless. Mike in Alaska

Scott, thanks for sharing the video. Maybe I'll go after mine now. For my -25F to 25F typical use environment, is this the right grease? Remember to re-do your PEC : )

So by putting 10 megs across the supply (you say in strategic locations), like at the source and on the power cable of the mount? They both are kept bled of any static buildup?

Ridiculous! I wonder if you did shots yearly if you would see quick movement near the core.

I haven't had any more squirrley USB issues since using Tripp-lite USB active cables to get from computer to pier. I have an active (cheap) hub on the end of one of them.

Looks great. Registax? What's the choice for stuff like this these days?

I have used a single power supply since 2007. It is a 15V unit I purchased from AP. I even run a noisy (...12V labeled...) heater controller from Kendrick off it at 15V. It has been perfectly behaved
