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

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: Looking for one or two CP3's

Christopher Erickson
 

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.

Roland, is Eric's encoder box compatible with the 3600?

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.

I have one I can send to you.  It's gathering dust in a draw.  I had updated to the CP4 last summer.

Re: Meridian Flip Feature Yet?

Ted Mickle
 

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.

So my thought is that I will give them a CP3 to keep them going but first I have to find one.

Thanks for the info Howard.

As I do have a 10" SCT and shortly a large refractor, I shall stick with the DOVELM162.

Re: Mach 1 not parking at Alt Az position

Thanks for the responses. I am using the AP V2 ASCOM driver. I can get the GTO CP3 firmware version later in the evening. I have a keypad but have never used it since the mount is exclusively used for imaging.

Re: Mach 1 not parking at Alt Az position

Hello Arun,

Are you using the AP V2 ASCOM driver, or APCC or something else?   Do you know what firmware version is in your GTOCP3?   Both APCC and the driver will tell you the version.


Re: Mach 1 not parking at Alt Az position

 

What is your setup? Are you using APCC and other programs, the keypad, or something else to send the command?

Hello,

I have a Mach 1 that is running off of CP3. I've programmed the Alt Az position to be with the counterweight bar horizontal and scope pointed straight up for flats. Recently, it doesn't quite park in that position; it moves very close to that position and indicates it is still slewing with very minute movements shown until I abort the park. Wondering if this is indicative of some kind of issue or there is way of fixing it? I have tried changing the alt az position slightly, but it won't park there either. It has no issues parking to Park 3.
