If you are trying to chase down a problem and think it might be the mount, the best way to approach it is to disconnect every program from the mount and run it without any external inputs. That means

Hi, Probably highly unlikely, but given everything else you have checked for the cause of the RA lurch, have you checked your counterweight’s lock knobs? If not very tight, perhaps one is very

I forgot to mention the fact that I am not guiding. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin -

It is working very nicely. I actually set up a 3 line point map run with declination spacing of 5 degrees and RA spacing of 11 degrees. Almost done with the data collection now. Have taken 100 of

I can't read any text on your pic. You can post the pic on IMGUR and link to it here. I have a similar problem - not an exactly repeating lurch, but often enough to be annoying. I got my grease kit

Hi Rolando, I have been getting similar spikes and was about to re-grease. But this sounds intriguing. Can I ask which log Andrew spotted this move in? I'd like to double check in my case and see if

Thanks Andrew. I am keeping my fingers crossed that we don’t need the flattener but that is good to know if we do. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery -

Download the instructions....basically there are two battery types based on your controller serial number. One is a direct replacement....the newer one has pig tails. The newer model ensures a better

I believe the AP side is English and the polar scope itself is metric and the AP bushing adapter is metric on the polar scope side and English on the mount side. So all you will need to do is English

Dean, I have been looking into the spacing of some of the older AP field flatteners. Many were configured for the Pentax 6x7 system. IN that case 86.5 mm is close to the 86.4 +/- 2.5 mm I thought was

Hmm, since the mount comes from 2004 or so. I highly doubt that it is metric. So I have ordered a new gauge which has both and more measurement options Tom

Hey Geert, sometimes ya' just gotta live dangerously. ;-) Thanks Roland, I can work with that. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/

"Could be more if the load is unbalanced and the mount has to work against the unbalance." If I use my Powerwerx meter to measure the watts (more precision than amps) in moving E to W versus W to E

The power supply is rated at 10 amps. The peak current draw at high slew rates (1800x) and both axes slewing can be as much as 5 amps. Could be more if the load is unbalanced and the mount has to work

I would prefer using the Moon to find the focal point, unless you want to set fire on a piece of paper :-) Geert Op zo 21 jun. 2020 om 18:42 schreef uncarollo2 <chris1011@...> via groups.io

Aim it at the sun, then place a piece of white paper at the focus point and measure where it comes to focus. Should be somewhere around 8" from the fully racked in focuser back. Rolando

I agree that practicing with your lathe will open a world of things you will be able to accomplish. I decided to get my lathe when I was quoted a very high cost to make a lens cell for a Zeiss flat

Happy Fathers Day to Astro-Dads! The Mach 2 AC/DC Power Supply terminates to an Anderson Power Pole connector. That Anderson Power Pole connector DOES NOT attach to the mount in ANY way.

Just replaced the battery of the hand of my AP900. Be careful; work slowly; be alert and it's simple. ;

Roland, is this a recent change? Best I can tell the connector on the 24V supply I have is powerpole. If not powerpole, it is a copy, and since this plugs into the power cord on the CP5, which
