Here we are, in France, in general confinement. Fortunately we still have, to us, astram, if our domicile and the weather allows it, to travel in the sky, but without sharing this pleasure with our

Cheng-Yang, Thank you for agreeing with my feedback, I am pretty pleased with the results on the Mach2 operation so far.. I think some others are questioning the results and I'm providing the best

Hi Terry, FYI, although I don't have a Mach2, I have an AP1100 with absolute encoders. For me, the PHD2 rms guide errors are *strongly* dependent on seeing conditions. Last week on 06 March, when the

That is why we pay the big bucks for a premium mount. :-) Now you can stop worrying about the mount. It fades into the background and reliably does its thing. -- Dean

Allen, The atmosphere creates significant star movement in my less exotic locale (at 155M in Vermont under the jet stream). And what I'm reporting is guiding (i'm actively guiding), not tracking.

Periodic error is completely corrected by the encoders but there are other sources of tracking error that must be minimized. The level of tracking error will depend on the amount of uncorrected

Terry, I am surprised to see the tracking you report as being .5 arc Sec. 35° above the Southern Horizon and .8 seconds of arc at 23° above the Horizon. It would seem to me that if the Mach II

Hello everyone, While we have an appreciation for reasoned debate, this topic has strayed. I haven't cut it off, but will be moderating every post on this thread. If your post is not about enjoying

Thanks, George. I will have to contact a local machine shop to see what they can come up with. Yours truly, Jack Huerkamp

I don’t agree with you Dale.you seem a bit hotheaded to me. Most physicians and Pathologists I have spoken with agree with me that the Media has overreacted, fanned the flames and has millions of

Just for you Dale.

Jack, We do not offer a pier extension for the 1600 mount’s 10” flat surface adapter (1612FSA). Regards, George George Whitney Astro-Physics, Inc. Phone:

I currently have an Astro-Physics Flat Surface Adapter for 1200GTO or 1600GTO Mounts attached to a 3/4" steel plate that is bolted to a dual lifting column system I made. When extended to their

That’s what I was thinking myself!

I ran add/remove programs and the only one listed was APCC 1.8.0.4. I removed it successfully and hopefully all files related to V1.6.0.4 were also removed. I then downloaded V1.8.0.4 from the

Hi Wayne, yes, I usually have it on. It might be interesting to do a test to see how much difference it makes. In other words, do the polar alignment with the correction turned on, and then try

I have used polemaster several times in an attempt to quantify differences with and without. I would call it more comparative than scientific as near as i can tell it doesn't make a difference for me
