Hello dan,

This is an element to take into account, but the powerbox is not a big computer and from what I see it does not really heat up.

Hello Dominique,
Congratulations on your purchase.
Do you have any reservations about having the heat from your power box disturbing the air in front of your telescope's objective lens?

Hi guys,
Mach2 received Wednesday at the end of the afternoon, tested in the lounge on the Eagle tripod, then installed the same evening in my observatory. RAPAS to roughly align (then disassemble), then by drift with PHD2. No worries with the latest version of the driver and APCC-pro.I even started to see how to model, but little problems with APPM / SGP connection. The next day I found the solution: open SGP as administrator. So Thursday evening, first successful 35-point modeling after some "no solve" because Arcsec / pix badly configured.Then photo test (3x10 ') on M109 without apparent drift, but the passage of satellites and (2x5') on Spica where there was clearly still drift. I am now waiting for the least amount of clouds to redo a modeling with more points and then a verification.And I also fully understood that if I bought this frame it was to do without guidance.For information, I installed a powerbox v2, but under the DOVELM162 plate and at the front with a fixed wiring which allows it to stay in place in case of tube change.

Re: Mach2 transport case

Dominique Durand
 

Hi Dean,

My mach2 is scheduled to stay in the fixed position, because I have a mach1 for walking. For this mach1 I used the Geoptik bag (Red) provided for EQ6 and I installed part of the protections of the original packaging reworked there. The mach1 lodges in park3 with its plate and I lodge there also RAPAS Price / lightness + protection + unbeatable size.
For the mach2 with the same frame it could certainly fit with only 49 to 51 lbs to carry. That is studied.

Mach2 transport case

Dean Jacobsen
 

Has any one found a Pelican case or similar transport case with the same inside dimensions as the Mach2 shipping box?  I saw a suggestion in the manual that the shipping box's padding could be used in a transport case.  That seemed like a good idea.

Hi Dominique,

You may be looking at two different rate types:

The fastest slew (Go To) rate is 1800x on the Mach 2.
The fastest move (button) rate is 1200x on the Mach 2.

Hi Ray,
I installed this latest APCC version. With the GTOCP5 no worries therefore.
On the other hand I noticed that on the driver V2 the speed 1800x was referenced and therefore selectable while
on APCC the maximum was 1200x.

OK, all is good.  I hadn't found the internal RA axis hard stops yet and when unpacking I was wondering if I was "unwinding" the RA axis in the right direction.

Hi Dean,

There are locking pins that prevent overpassing 180 ° East and west and north and south on the axes. It is rather outside that it happens, because you have to find the suitable cables or have connectors to make the DC cables for the arrival (bottom) and the output (Top) of the 12V.So in particular a specific power cable at the right length for the Powerbox as far as I am concerned.

No bias on either axis. Balance the mount properly and it will guide very well.

Sorry if this has come up before...

Is there any need to slightly bias the weight of the counterweights to any side of the mount with the Mach2?

Hello Astronuts,
 
Finally had a night of clear skies where i could test the Mach2 with my 160EDF scope. I am finalizing some new features in the keypad which include tracking limits that were recently requested, pointing modeling, unguided imaging and other neat features. We are finishing up the new software an hope to have keypads ready for customers very shortly for all CP4 and CP5 controllers.
 
I would like to share some results from last night:
The setup was my 160 EDF scope with a QSI 683 camera. I started the session while the sun was still up and ran a simple pointing model using stars from first to about 4th magnitude with an H-a filter and .05 sec exposures. I was able to center the stars manually on the crosshairs via the keypad, using MaximDL imaging software. I started with the scope under the mount with stars in the east along a constant Dec line that the object is on. The object is a group of galaxies called the Eyes, part of Markarian's Chain. The Mach2 allows you to place the scope under the mount if it can clear the tripod, so you can image all night long without flipping. It also has dual high res encoders that eliminate all periodic error and can be driven in both axes, very smoothly, at custom rates.
 
I centered 8 stars along the Dec line and entered them in the mount model memory. I purposely misaligned the pole to see how well the model would work for quick eyeball PA such as you would get if you set up in the field and are a bit lazy (like I am usually). I'm guessing that my PA is off by about 1/4 deg or more based on the amount of drift I was getting.
 
Is it possible to get round stars, being not polar aligned and not guiding, but simply relying on doing a quicky model? And not a full all-sky model with umpteen terms, but just 8 points? That's what I aimed to find out.
 
So, here is the setup: 160EDF, Mach2 mount, QSI 683 CCD camera, light weight Losmandy tripod, laptop with SkyX and MaximDL. The keypad routine is simple - click on a star in SkyX and slew to it, center it in the image in MaximDL, then press Enter on the keypad. Go to next star and repeat. Takes a few minutes each and probably could be automated, but for 8 stars it's not a biggy for hands-on operation.
TBD in next post
Roland, ready and willing to do some testing.

The tests look great.  This will be great for us remote imagers.

Hello some more ;^))

I took some 30 images over 3 hours almost continuously without touching the laptop, except to re-focus a couple of times. In the final stack i threw out 3 frames that had heavy satellite tracks (some right thru the central galaxy), and simply combined the rest in MaximDL. The end result is not great as far as getting deep sky results because of my horrendous light pollution, but that's not what my goal was anyhow. The goal was whether i could achieve a high res image without guiding using a simple keypad generated mount model. Below is a 50% size image which I am hoping doesn't exceed the max image size. Stars are round to approx .033 as measured by MaximDL, taken in 2 out of 5 seeing according to Clear Sky Clock. No field flattener, just straight out of the 160 lens and onto the 8300 chip.
