Cable broken

Dean Salman <cluster@...>
 

Well it happened, the impossible. The DEC cable got caught under the
big knob used to attached the DEC housing to the RA housing during a
park. The cable works but I don't trust it anymore because the end was
damaged. If it was a longer cable, I think it would be possible to
route it under or next to the polar shaft and come out in the front. I
might look for some tubing today to place around the cable so that is
larger. Round caps like that put on eyepieces (the soft black ruber
ones) might also help

Any other ideas?

First light report AP1200GTO

Dean S
 

WOW, what a fine piece of machinery!!!!

Got it set up, scope and camera mounted and balanced, and connected to my laptop, and communicating with the software just fine, which is amazing for me. Got familiar with the hand controller while impatiently awaiting darkness. BTW, packaging was outstanding and makes a great first impression.

Polar alignment was a breeze, sure do love the smooth adjustments of this mount, and the rotating pier adapter is sweet. Then synched on my first star and I was off.

I used the telescope control in MaxIm for the first time, hand controller cord was to short to reach my warm room, and it did a remarkable job getting everything near center of my chip, then a couple nudges to adjust. What does the Synch button in Maxim do? A true synch, or a recalibrate? I did try the Sky6 and it connects fine to it, and I saw the new recalibrate button too.

The seeing was extremely bad and jumpy but I tried using my STV to monitor the drive in slow, this was disturbing to me. At first I thought the darn STV display had locked up, so I started it again, several times actually. Well, it turns out it was working, this mount is soooooo smooth it was tracking almost center of the graph line and it was hard to even tell! And my alignment then showed only a very small drift in 5 minutes, must have been beginners luck, or just good equipment I suspect.

I downloaded the AP installed PEC file from the mount, and it showed it to be peak to peak 3.7 which is outstanding in my book for raw errors. Later in the evening with things settled down a bit I did a couple pempro runs with PEC on, my image scale is 1.12 arcsecs, and it showed me peak to peak of 1.55 arcsecs!! I can live with that :)))))

I had some trouble with over correcting when guiding due to the seeing, so I need to experiment with this mount and find out what it likes best. But I ended up imaging NGC891, and M1 using 4 minute unguided 1x1 lum subs and they came out great, even considering my poor seeing and transparency.

I feel like I am in love for the very first time :)

Thanks for such a fine mount Roland, Marj, Howard, Robert, and all the gang at AP!

I have been following the group with great interest over the years but
never actually posted. Sorry. I was just wondering what sort of
quantities are produced in the AP line of products, primarily in
telescopes and the MACH1 GTO. I am thinking of getting one or both of
them very soon. I assume its like 50 at a time as I am looking at these
serial numbers.

Target Declination Rejected

Mark Galiyano <mgjr@...>
 

I am currently having an intermittent (sometimes once per imaging
session) issue where my mount is rejecting requested declination
coordinates. I am running my new AP1200 in an automated environment,
using DC3's ACP. This seams to happen most when the mount is already
close to the desired location (as in after solving a plate and
reslewing to center the desired target) and causes the automated
script to abort and park the mount. Immediate subsequent requests
for the same declination result in correct behavior.

I am using a built in (not USB) serial port to the mount, and a 6.8
Amp 13.8 VDC power supply that powers only the mount. I have
captured the serialtrace of an event and also used the ASCOM Pipe to
monitor the traffic between ACP, the ASCOM Driver and the mount. The
following are snippits of these logs:

From ASCOM Serialtrace.txt:

[18:57:01] Transmit(":GR#")...
[18:57:01] ...done
[18:57:01] ReceiveTerminated("#")...

[18:57:06] ...done
[18:57:06] ReceiveTerminated("#")...
[18:57:06] ...received "+42*18:43#"

From ASCOM Pipe.Log:

RightAscension: 02:23:34
Declination: +42:18:42
TargetRightAscension: -> 02:24:14 (done)
TargetDeclination: -> +42:15:18 (Error) - 80040418 - ASCOM
AstroPhysics GTO Driver - AP mount rejected set TargetDeclination =
+42*15:18
RightAscension: 02:23:35
Declination: +42:18:42

I have reviewed the serial protocol documentation in the AP GTO
Keypad manual but did not find any explanation for why the mount
would reply with a "J". Does anyone know if this is an active
rejection of the declination coordinates? I will continue to trap
events that occur, I know there are atleast a few others out there
having this issue (I first posted on the DC3 forum).

Sorry for the long post ( and placing log snippits in the post ).
Thanks for any assistance,
Mark Galiyano

Hey Jeff,



Clever idea using the slip joints in that way. The housings shouldn't
really be all that tight in the first place (I hope! As I've said
before - Don't think lug nuts!). The alternate method may really be
the safest in terms of avoiding scratches and tooth marks on the
connector.

Howard --

Nicely done.

When unscrewing mine, I used a pair of slip-joint pliers across the
inner ring, with a tooth of one jaw in the gap in the ring, and a piece
of cardstock opposite to keep the other jaw's teeth from marring the
ring.

I haven't tried the needle-nose pliers yet, so I don't know which is
easier. The needle-nose method is certainly safer as there's no chance
of deforming the ring by squeezing too hard.

The Mach1GTO uses a different connector at its motor boxes. In fact,
it uses a similar connector to the one that is used on the keypad.
(It is the six pin version. The keypad uses the five pin version.)
The new document will not be difficult to produce, since it will be
almost the same as the one for the 900/1200. Like the 900/1200, both
axes' individual plugs are wired in the same fashion. If you are in a
hurry, here is the pin information:



#1 Black & Gray Motor -

#2 Red & Brown Motor +

#3 Yellow Ground

#4 White Encoder Ch. B

#5 Green Encoder 5 V.

#6 Blue Encoder Ch. A
