Hi all, I'd like to share this image of SH2-101, the Tulip nebula, done with my Riccardi Honders astrograph back to home after an optical repair. The scope now free of astigmatism is really impressive

LOL! I know. It was actually on my G11 being used for visual. It was on the pier beside the Planewave/Paramount. I got a mouse infestation in the Planewave and they tore out the heater wiring harness.

Putting an AP155 back into action as an "impulsive" act. What a concept! Christopher Erickson Consulting Engineer Summit Kinetics Waikoloa, HI 96738 www.summitkinetics.com

In this case backlash has no effect whatsoever on RA. The gears never reverse, so any reversing delay is not applicable. Rolando

Wouldn’t you want to send both the DEC and the RA at the same time. Then they are both starting from a known baseline. Would suck to do only the Dec and then 6 months later have an issue with the RA

“It's a very old mount, probably has been slewed around the sky for many many years. Eventually the teeth on a metal gear will wear. The solution is to send the gearbox back and we will fit new

Christopher, I agree mostly with what you said. I think in my case, the rings are old and the felt is pretty much crushed so my 155 isn't moving in the rings like it might if the felt was

The only scope I have ever owned that didn't suffer from differentialflexure between a piggyback guide scope and the main scope is my AP130EDF-GT. That is why I ONLY use off-axis/radial guiders

I don't have any pics of an imaging setup on my 900 right now so Iwould have to set up and take some. These days I mostly image with myMach1+130EDF-GT+SBIG STF-8300M/FW5/OAG/STi and use my 900+C14

Vince, you want the guide scope/camera to be fixed relative to the back of your imaging scope. Ideally mounted on the focuser but with your scope that seems impractical. You could try a second pair of

Hi, I am not sure how I can better fit the guide scope to the mount. If you could give me a picture or something to show me the best way I would be really happy to modify my setup. The cables are also

Hi George (and Rolando in previous message) Rolando>>It's a very old mount, probably has been slewed around the sky for many many years. Eventually the teeth on a metal gear will wear. The solution is

Timo, It is hard to say how the previous owner used the mount. Yes, wear can occur at different rates. We have customers doing supernova searches which require hundreds of slews nightly.

Your steps don't make any sense. Rolando

Hi Konstantin, >>have ever tried and set a backslash time other than 0? Nope, but I think we should get backlash minimized with other methods, before we start doing compensation in software. That's

If your mount is lost and you center on Vega then move mount and park-0. The mount is still lost. You must Recal after centering on Vega and before move mount and Park-0 Jimmy 33.6N, 88.6W

Hi Konstantin, >>have ever tried and set a backslash time other than 0? Nope, because in my discussions with AP support they always sais that I should remove any backlash setup from GTOCP3 and do the

Hi George, >>Sorry, for the delay, I have been out of the office for medical reasons. It is best that you send your Dec Motor Gearbox to us for examination and repair as needed. I willsend you a
