Re: Mount Maintenance

AP sells a grease kit for their mounts. This comes with everything you need including a brush. There is plenty of extra to apply a thin layer to the mating surfaces between the DEC and RA on a 1200GTO Mount. I just purchased a kit myself. I love doing business with AP.

I assume that as on the 1200 it is the joint between the Dec and RA.  I use a waterproof grease.

Hello all

I was reading the Mach 1 GTO manual as I do from time to time to refresh my memory.  I noted something that I either didn't read before or just forgot.  Under the "Mount Maintenance" section (pg 31 or 32 depending on which version) it states "If the RA and DEC axis are attached together for a long time in outside conditions (i.e. in a permanent observatory) then the mating surfaces should be lightly oiled or greased - if you expect to get them apart again after 10 years".   This is my situation and I've had the mount for 6 years or so and plan on doing this maintenance as soon as it gets a bit warmer up here.  Three questions:  1) I assume this is the joint directly under the DEC clutch knobs?  Or is it the "lower" joint at the RA clutch knobs? (see schematic on page 7)  2) If anyone has done this - is there anything I should be aware of before I start?  3) any recommendations on oil or grease types?

Any help is appreciated.

Remote power on/off via USB relay Arduino CH340. Maybe add it to APCC?

Micheal Fields Jr
 

Looking for a way to restart the mount I ventured onto Amazon and found this little USB relay device https://www.amazon.com/gp/product/B01CN7E0RQ

After poking around trying to figure out how to use it easily I found that documentation was limited and so was software.  I found a helpful youtube video https://www.youtube.com/watch?v=26XHb_cpiAA and the youtuber also provided example power shell scripts and a link to a piece of software that sends hex commands to the device to toggle on / off.

I found the power shell scripts more useful.  Here is an example to turn on/off

ON:
[Byte[]] $powerOn  = 0xA0, 0x01, 0x01, 0xA2
[Byte[]] $powerOff = 0xA0, 0x01, 0x00, 0xA1
$robojax = new-Object System.IO.Ports.SerialPort COM7,9600,None,8,one     <---- Note the com port must match what your windows sets for this device.
$robojax.Open()
$robojax.Write($powerOn, 0, $powerOn.Count)
$robojax.Close()

OFF:
[Byte[]] $powerOn  = 0xA0, 0x01, 0x01, 0xA2
[Byte[]] $powerOff = 0xA0, 0x01, 0x00, 0xA1
$robojax = new-Object System.IO.Ports.SerialPort COM7,9600,None,8,one
$robojax.Open()
$robojax.Write($powerOff, 0, $powerOff.Count)
$robojax.Close()


So it occurs to me that this device is a nifty and inexpensive way to toggle your mount on and off as opposed to the more expensive remote power strips, it would be nice to have this somehow added to APCC where we can slide a switch on  or off and send these commands to the relay board and perhaps as an added bonus be able to specify a delay in seconds.  Eg, turn off for 10 seconds and then turn back on again.

And again yes I am familiar with remote controllable power strips where you can turn on and off certain devices. These are great for remote observatories for sure.  If you are going to spend this much on equipment you probably should go that route anyways.   

If it isn't a big deal to add this to APCC though, that would be wonderful to have.  Hi Ray!

The GTOCP3 will work, but the personality will need to be changed.  I can send you a script to do this.

The UofH VYSOS project also has a 3600. I wonder if the encoder box is compatible with the 3600. If it is, I might be interested in buying that as spares for their 3600 for when their budget is eventually unfrozen.

Ok George I dont think they was long but I will check 
Thanks steve


Re: Mach1

George
 

Steve,

 

Check the length of the screws that secure the dovetail saddle to the Dec top plate.    The screws should not extend more than ¼” to 3/8” beyond the thickness of the dovetail saddle.

Hello 
I have got a issue with my mach1 I have owned the mount for 3 weeks now and the mount seems to be grinding on something on the dec axis when there is just the dovetail clamp on it and when its loaded up it's very difficult to move I have made sure all the clutch knobs are loose i have stripped the top part down given it a good clean made sure the clutch brakes (not sure if thats the correct term) are clean and free reassembled but no diffrent.The ra runs smooth and free  so I can get a good balance in that direction but no chance in dec. The mount is a 2014 model not sure if that matters

Re: IC434 first picture for my AP MACH2 and custom built corrected newton #Mach2GTO

Jim Gerlach
 

Hello Andrea,

Beautiful photo of IC434.  I am new to the group and am wondering about your "nomad" set up.  Is your set up on a tripod with "wheels" or do you have to tear it down to take it outside?
Is it possible for you to post a photo showing the lower part of your set up.  I just put myself on the list for a MACH2GTO.  I currently have a system where I wheel my set up out of the garage into the driveway to do my imaging.

Jim

Re: Meridian Flip Feature Yet?

Marj,

What new capabilities will CP4 owners enjoy with Version 5 compared to the current keypad version?

Thanks,

Ted

Ray,

The new keypad version 5 is not available for the GTOCP4 yet, but will be soon. The instructions for the flip are in keypad manual. This manual must be updated for use with the CP4 since there are some critical differences in other functions.

The flip is not based on meridian delay. The scope flips when you press the button. This feature is in the CP4/5 version P02-08 and is activated via the latest keypad software.

Hi Rolando, 

Is this pier flip based on meridian delay? Or is it an instantaneous dedicated flip feature? And is the hand controller path inside an AP instruction manual somewhere? I want to check it before purchasing the CP4 that I'm told I need, thanks again.
