Mach1GTO case recommendations?

Derek K.
 

Dear AP mount owners,

I have a Mach1 from the final production run and it’s been a pleasure to use in my backyard.
When transporting it in my sedan I’ve resorted to the original AP shipment box&foam plus towels to cushion the package. This worked ok (even on the long and winding road to a Lick observatory outreach event) but I’d like your thoughts on better options.

Ideally the case would also accommodate 14 and 9 point counterweights (one each), cables, GTOCP4, CBAPT, standard counterweight shaft and be resilient yet lightweight enough that I could use it for airline transport someday. Willing to consider other options if there isn’t a good compromise.
I saw an advert for a “Doro” waterproof case with foam shaped to fit the contours of the mount. Seemed nice but I was too late to snag it.

Regards and hope all are doing well in these troubled times,
Derek


Re: Tracking problem with Mach 1

Peter Bresler
 

I had a lengthy session with George yesterday. PHD2 now is working. I still am having tracking problems with short exposures, which I did not have previously. It is possible my concrete pier shifted slightly in the rain. Last night I got polar alignment in one direction, but it was off in the opposite direction, so I am assuming the mount is not level, although the bubble level on the mount is on.

If you are connecting the CP4 directly to your PC you probably need a cross-over version of the ethernet cable.  If you have a router, plug the CP4 into that.

Problems to update CP4 firmware

Matthieu BUI
 

Hello, since I installed the last ascom driver, I lost some windows on the driver setup.
I was told to update my CP4 firmware to fix bugs.
Here come the problems : Il canot connect my CP4 with ethernet cable. I tried to plug it on my PC and on my Imac but the IP canot be found.
When I connect with a wifi protocol, I could check the ethernet IP I use is the good one (in ethernet settings).
When I connect the cable in the powered on CP4, the leds on the ethernet port do not lid.
As I never used this port before, I can't say if it worked one or not.

Is there something to do to fix it ?

Regards

Always good to err on the side of caution. Use only accounts for a portion of the grease degradation. Age is a factor as well. I found after re greasing my AP900 (2009 vintage) that the gear train purred like a kitten! I could tell the original grease had dried out because the gears were quite loud especially slewing at 1200X. There was also a tic tic tic sound in the gear train in the Dec axis which was gone after re greasing. Probably due to a dried lump of grease in the gears.

I decided that at my Mach1's age (second run 2007) and it's new use, slewing around the AP254 with 60# of counter weights I should re-grease it. The mount does not sit outside and is used for visual not photography so it's had a gentle existence.  Ordered re-grease package from AP earlier in the week and it arrived today.  Small jars of the spur and worm grease but  it's enough goop to do the job numerous times. 

Took about 3hrs start to finish with a very deliberate approach.  It might not have really needed it.  The original grease was still in abundance but the worm grease looked a little separated. Regardless I feel better knowing it is freshly lubricated.

I was trying to point out that below the top window the lower one is showing COM Errors. That could be that it took a while to connect before acknowledgment and simply hasn’t been cleared or maybe an active COM issue. That’s what I was referring to.

If there are Com errors then there may be no connection to the mount, and therefore the mount might not even be initialized.

Here are current settings. ASCOM is showing the correct mount and control box. I do not see how to change these ins ASCOM. only in APCC. It shows the mount as tracking, but last night it was not. I would appreciate a phone call at about 8:30 PDT to see if the problem has been resolved.

I put the mount tracking the sun with the lens cap on. Will see if it moves during the day.

Just look at the motor shaft. If it's not turning then it's not tracking. No reason to wait until tonight.

Do you have a keypad (hand controller)?

The gear box did not show any movement.
I assume you mean that the motor shaft is not turning. But since the motor does slew, then you probably have selected STOP on one of your apps. There are 4 tracking speeds, Sidereal, Solar, Lunar and STOP. The last one turns the motor tracking off, so please check your apps to see if one of them is set to STOP.

Better yet, if you have a keypad, plug it in, remove all external apps and set the keypad to sidereal rate. Then check the motor shaft to see if it is turning.

I still had the problem last night. The gear box did not show any movement. Parks and slews are normal; there is no mechanical problem with the mount. It either is software, or a problem with the control box, which I was beginning to suspect. I checked rate settings in both APCC and ASCOM, which were on sidereal. The readout on APCC says the mount is tracking, but it is not. Ray suggested in a private email that the wrong control box may be selected...I will recheck that, and repost. PHD2 gave an error message that the mount was not responding the pulse commands.  If I cannot get this resolved, a phone call during viewing hours would be nice. It looks like it has cleared up here on the central coast.....maybe phone me around 8:30 PDT, 805-801-4607? I need my mount back!

IC 2631 is a blue reflection nebula in the far southern constellation of Chamaeleon. It surrounds a young T Tauri star HD973000, about 500 light years away. It lies in the Chamaeleon Cloud Complex which is a large star forming region that includes the Chamaeleon I, Chamaeleon II, and Chamaeleon III dark clouds. The Chamaeleon Complex occupies nearly all of the constellation Chamaeleon and overlaps into Apus, Musca, Carina and Octans.

The final spur gear on the worm will turn once every 6.4 minutes. The motor shaft turns once in just under 8 seconds.

I was having problems with the ASCOM driver a few days ago.I took the photo after I recorded the log, but was the same as was occurring while the log was running. I checked for obstructions....none found. How do I tell if the motor is running at sidereal rate? A mechanical problem would be something new. No problems at all with tracking until now. Change in polar alignment also very unlikely but I will recheck it.

In addition to Ray and Roland's recommendations, make sure that the ASCOM driver wasn't set to an unintended tracking mode such as solar or lunar.
