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

My 1963 Colchester Student lathe cuts both metric and imperial threads but most lathes of that age did not come equipped with such gearboxes. Modern lathes should cut mostly metric threads unless

Jumping in here.....I also have a larger metal lathe, milling machine, etc.in my home shop. Your mini lathe is setup for ASA screw sizes and it does this with a lead screw that allows the

I guess I could guesstimate the focal point by measuring 43” back from the front of the objective and then measuring how far it is from that point to the focuser barrel. -- Dean

However the various adapters that AP makes adapt the Kenko polar scope to the English threaded holes on various AP mounts. They make more than one bushing adapter. I don't know which one you have.

The PASILL polar scopes are made by Kenko in Japan. Yes, metric threads.

Hi Well it turns out that the diameter of the threads is very different than the Passil4 on the 900. Which is strange...The diameter of the threaded part is 1.016 inches and the threading is not

Thanks Stuart. Sounds good. I figure that having the camera in focus with the focuser barrel about 1” extended would be a good place to be. So I was hoping to avoid that situation I am sure we
