Hi Some new messier image on my home page,you can see them (messier8,m17,m13,m92,m57,m22,m21,m23 and ngc6826) at http://perso.infonie.fr/visonneau-vin/news.html Bye Vincent from France ---------------

During the last week, somewhere in the discussion about clamping handles for the AP 600, the suggestion came up to add a nylon washer -- either under the metal washer, or in place of the metal washer.

Has anyone ever experienced problems connecting the SBIG ST-7 to the AP 1200 GTO? When I connect the St-7 TIC-cable to the mount it starts to move westward. I checked cable connections/pinouts but I c

Hi everybody I am a newbie on this list. I am retired and I live in Provence in the South of France. I built an observatory above my garage in the garden. I received my new telescope one month ago. It

I notice that the there are 2715 Abell galaxies listed in the GOTO Keypad listings for my 600E mount. (Not all the Abell objects are covered). Is there a "master" list of these somewhere as I don't wa

Hello, First, let me apologize to members of this group who are south of the equator... When doing the 'N Polar Calibrate' is there a list of good stars to use for this exercise anywhere? The AP manua

Hello, I am a new owner of a 600EGTO mount and have had a couple of opportunities to use it. One thing that is obvious is that I am going to need an illuminated reticle for the callibration routine. A

Quick question. I have tried to be very careful in balancing my one month old 600 prior to each use, but I might be doing something wrong. The challenge I'm having is that the instrument I'm using is

The government announced today that the purposeful degradation of the GPS (Global Positioning System) signals available to civilian users will end tonight. With selective availability (SA) disabled, a

Well I did the best I could to create a decent cell for the Baader solar filter material. It appears to be VERY serviceable cell if I do say so myself. However I must say it looks like total hell. I d

AP 155 EDFS, AP rings on 16" Parallax Dovetail on Parallax 125 with AP GTO. I have had this out several times now and have been unable to get it to point accurately - place and time setup are correct.

What is the pointing accuracy of the A.P.1200? Assuming everything is accurately set up, and polar aligned, what do you normally get? I would imagine that this feature, which I've never had, is pretty

I am anxiously awaiting my mount, but am wondering about the Davis and Sanford aluminum tripod.Is it a good choice or is the wood tripod a better one, or any other suggestions. i am planning on using

This past weekend in the Everglades, A question was posed to me "does your AP1200 mount have the King tracking rate." I checked the menu to find only the Lunar, Solar, and Sidereal tracking rates. The

On AP GTO, does the declination axis position on powerup matter? I know the RA axis should be visually aligned to Polaris and the mount should be fairly horizontal. Is there an optimal position for th

Just out of curiousity I'm wondering how long others have managed a typical unguided CCD exposure. I've managed 4 minutes once at F/5.0 but most of the time despite good "drift aligning" I can only ge

My mount is still resetting (A/P 600 GTO) Out of nowhere it just resets and keeps running, but loses it's whereabouts. I am now using a different battery (suspecting fluctuating voltage in the old) an

Anyone used TPoint from Software Bisque to improve their AP Goto accuracy? If so what were your results? Worth the money? Effort?

Suppose I set the scope on M3 and hit the "Recal" button and then move on to the next object and "tweak" that position with another "Recal". Does the keypad "remember" each correction and thus improve

If you "train" the PEM at 1x or .5x what speed should you set the keypad at when playing back the PEM? I usually have my speed set at 12x and leave it there for the observing once set. Does this setti
