Re: Paint color for mounts?

Joe Zeglinski
 

Jeff,

Your painter should do a colour match, before final application, since
paint ages, and your AP mount colour could have changed a bit. You would hate
to see the OTA differ, however slightly, from the mount colour, and if the OTA
painting process is "powder coat", it would be difficult to change later. I'm
not sure, but since the mount has a rough surface, and the OTA will be shiny
smooth, the same paint colour may appear to be different on such different
surfaces - unless you choose a satin texture spraying, or satin "clear coat"
if not using the powder coat paint process.

Just some thoughts,
Joe

GPS on a German Equatorial Mount

Roland Christen
 

Hello All,

Marj informs me that our main competitor has now offered a GPS for the Gemini
GoTo system. I realize that GPS is vital for Alt-Az mountings, since tracking
rate of any object in the sky is variable and directly affected by your
location on earth. However, since the tracking rate of a polar aligned GEM is
always fixed at sidereal, I question the need for this added complication to the
system (another thing to go wrong out in the field). Myself, I think of it like
having anti-lock brakes on a speedboat, however Marj is totally convinced that
we will need this vital bit of technology in order to not be left behind by
the competition.

So what exactly does GPS offer to a GEM (it won't help you to polar align)?
Any thoughts from the advanced users out there?

Rolando

Re: Mach1GTO with Losmandy G11 tripod

Joe Zeglinski
 

Roland,

What a wonderful surprise - is this something new?

If so, have you got an "AP900 to Losmandy G11 tripod" adapter plate for me? I
was just about to have one machined, but would prefer an AP professionally
made adapter.

Hopeful,
Joe

Mach1GTO with Losmandy G11 tripod

ayiomamitis
 

Rolando,

I have seen a number of comments about using the Losmandy G11 tripod
with the Mach1GTO and this is something which I would also like to pursue.

Are there any plans for AP to make the necessary pier adapter plate
which would allow the mating of these two pieces of equipment?

Having used a Losmandy G11 for many years, I really (!) like the very
solid and steady tripod available from Losmandy.

Thanks.

Asteroid tracking

davidjmcdonald
 

Are there any plans to provide the ability for the AP1200 ASCOM driver to
support non-sidereal rates (e.g for tracking asteroids)?

I know it can be done in the current PulseGuide software, but apparently not
via the current ASCOM driver. Unless I missed something...

It is not necessary to precisely balance any of our mounts. The axes and

axis,
just grab the end of the counterweight shaft, turn it horizontal and feel
the
difference in the amount of weight. If it feels about equal, you are close
enough to balance. For the Dec, grab the end of the tube assembly and do the

Do not obsess about getting the balace exact, or even bother to load it

Re: Is an adapted Losmandy G11 tripod good for an AP900?

Joe Zeglinski
 

Thanks Stuart,

That is indeed reassuring.
I had a fear that the several "levels" of screws or bolts could still leave
the assembly shaky - i.e. too many couplings in the stack. In my setup I was
going to use the 3 screws to bolt a machined G11 "transition collar" to a
standard AP, FSA (flat surface adapter), which is then bolted with 6 screws
to the AP900. I may have the 6 holes in the FSA sides milled out with slots,
so that I only need one AP rotating adapter plate, and make it easy to just
"drop and twist" the AP900 onto the stack, the way that Losmandy designed his
G11. I really hate fussing with a pocket full of screws, in the dark, and
cold - even worse if they have washers as well (really dumb approach).

I did have a concern that these two layers, or levels, of screws could
result in a bit of play. However, by your 12 inch solid extension example,
there should be no such problem.

Regards,
Joe

Joe, I have exactly what you've described and it works great. I have the
Losmandy G-11 Tripod with 12" extension and my AP900GTO on top and it
doesn't budge. I loosened the tripd knobs that allow the leg extensions to
slip right into the main body of the tripd so it sits as low as it will go
but there is no vibration and no risk of one leg slipping over time (mine is
a permanent set-up).

Hi,

Recently, I discovered that my convenient QUICKSET "heavy duty" TV camera
tripod, adapted for the AP900 base, turned out to be very shaky - with all
huge weight of the AP900, counterweights, and 7 inch MAK - in spite of the
tripod's obvious mass. On the other hand, the G11 tripod, which is a "welded
aluminum" superstructure, with large diameter leg pipes, seems to be extremely
solid and stable, in comparison. I think the fact that it is welded, instead
of having articulated bolted on, folding legs (even with a stiffener), makes
the Losmandy tripod uniquely rock solid.

I am reluctant to go for one of the typical telescope tripods now, with
concern for wobble at the leg attachments, etc. I also don't like "tie-rods,
turn buckles" and other ship's rigging on a telescope field pedestal. In fact,
the original plan was to immediately replace my new Losmandy G11 tripod with
my old TV camera tripod - assuming that it easily carried the weight of those
huge olden day cameras. I soon gained new respect for Scott's design.

Before I have a special AP900 to Losmandy tripod adapter machined for me,
I would like to hear any opinions on this approach, hopefully from your
experience with this tripod and an AP900. Actually, I wish AP would have this
"tripod adapter" as part of their Losmandy made OTA adapter product line
(hint).

Thanks for any advice.
Joe

Re: optec tcf s compatibility with edgeport serial to usb converters

Yves Laroche
 

Hi Jerald,

On my side, I've experimented serial timeout issue with my 1200GTO mount when using my edgeport/8 with my TCF-S in Automode A or B. The problem seemed to happend when I was using MaxImDL with the focuser's auto tracking function enabled. By default, each time the TCF-S automode function is enabled, the controller box sent data back to the serial port, every one second, to let know the software about temperature and focuser position. These informations produce a lot of traffic jam and block other data to be sent back to other serial port like telescope mount. This traffic jam produce a bad serial link on other serial link and it produced disconnected link. Also, I've set ACP4 polling option to slow but without success.

To solve my problem, I've ordered the last chip upgrade from Optec. The new firmware permit a user to cancel any data from being sent to the serial port when using the automode focuser command. This new command "FQUIT1" solved my serial traffic jam problem.
