Guider settings

Suresh Mohan
 

Yesterday after having found that guiding worsens my stars . Scope at present is just a 135 mm Samyang lens And qhy 193 M / finder scope 175 mm And lodestar gibbing me 3.67 asp/9.14 asp( guidescope ) . Could this be the reason why my guided results are poor when compared to unguided ?

Re: How critical is balance ?

I found the culprit ; the 10 min unguided has no drift !! So I need to re look at the guiding parameters !

I’m noticing a tiny trail only in RA only after it crosses the meridian . However I balance east heavy only with the cw bar horizontal . Should I offset it a little more than the existing east heavy position ?
Thanks

I looked at the Mach2.
I have been waiting for it and missed it !!!

But yes George  ..and then send the mounts ... we will manage since it seems that now everything is automatic.

YES it is George's and Rolando's fault that you/we are are getting such suburb service and equipment.  It is worth the wait to get things correct the first time 1111111111111

This is where AP publishes the manuals and docs for current products:

https://astro-physics.info/index.htm?tech_support/tech_support

I have been watching there for the Mach2 manual and also the GTOCP5 manual and the manual for the new keypad revision.

It is not yet available as far as I know ... since George is still working on it.

apologize to all who are waiting patiently for this mount.
 
Yes, it has taken longer than anticipated for us to finish the first batch. This mount is totally new and quite different in many ways from our previous versions, even our previous encoder mounts. Where we used servomotors and gears before, we use brushless microsteppers and belt drives in the Mach2. They react differently to loop commands and we have different software to control them. All this had to be tested thoroughly on the production mounts before I was fully satisfied with the performance.
 
Parallel to the mount development we also have new keypad software for the Mach2 because this computer mount has certain operations that are different from our previous encoder mounts. Some functions are now automatic and not settable by the customer - such as Resume from ParkX or Present Position etc. These and other annoyances have all been eliminated in this mount because it is now automatic, you don't have to remember anything because the mount always knows where it is.
 
We have also added new features to the keypad to make it far more usable and easier to operate. Things like modeling took a lot of time to develop and test, and our skies this winter prevented most testing for weeks at a time. Nevertheless we are finished with the mount portion and are doing final testing on the first batch. I am very picky about how the mounts are assembled and watching every step as our technicians put them together. I am personally doing the test protocol on every mount myself at this time, to make certain that every one of them meets spec. Last thing I want is for something to happen to a mount that was shipped and did not work correctly at the customer's location. When these first production units are done, we will automate our testing and be able to do it at a faster rate for future production.
 
I think you will find that the performance of the Mach2 is at a much higher level than other mounts of its size range. It was a personal dream of mine to produce a high precision imaging mount and it has taken a number of years from just paper sketches to Cad-Cam design to analysis to actual cutting of metal. It will track extremely accurately and won't require constant corrections in PHD2 at high guide rates to keep it on the straight and narrow. And of course it has excellent potential for unguided imaging with any focal length scope. In fact I plan to do just that with my 10" F14.6 Mak-Cass., weather permitting, and I will show you the resolution that is possible under reasonably good seeing.

Hopefully those who will receive a Mach2 in the first group to ship will share their experiences with these great new features.  I have been watching for publication of the manual so I can start learning about the mount. 


Re: APPM 239 Point Model....Is This About Right?

Ray Gralak
 

Just wondering what sort of range is acceptable?
The graphs looks reasonable. There is no particular range as it depends on the equipment being used and how well it can be modeled.

East west drift after 10 min

Suresh Mohan
 

This is the drift I noticed in the 10’min guided 03 exposure (after crossing meridian ) . There are no changes in guider graph . E W is top right to bottom left . I will test more tonight . Thanks

Hi Suresh,

all M1 are spring loaded! Perhaps you need to re-mash.

Hi ,
I’m using a Mach 1 mount , my gear at present is just a qhy183 M with a Samyang 135 mm lens , I’m presently shooting sh2 308 . I’m wel polar aligned with no DEC drift . I’m noticing a tiny trail only  in RA only after it crosses the meridian . However I balance east heavy only with the cw bar horizontal . Should I offset it a little more than the existing east heavy position  ? 
Thanks 
Suresh
