Another Mach2 video

Harley Davidson
 

I had a guy on my YouTube channel, Tim Morrill request a video of how the motors sound on the Mach2. He was still waiting for his to be delivered.

I set it up in my garage to reduce all the sounds I get from living in the country. Also, I'm not using a high end camera for my videos. It's a small Nikon. The "slapping" sound while the motors were running is the keypad cord hitting the tripod leg [I didn't catch it at the time, oops]. The motors have a very nice hum to them.

PntON on Keypad and APCC

Dominique
 
Edited

Hi AP,
For use without guiding my current model on the Mach2 brings a small drift without consequence on the poses of 3 to 4 'but which for sessions of 4 to 5 hours of exposures causes a gap between the first and last which makes the trails appear. difficult to deal with on the end result.
It is therefore an opportunity to test the Point + track mode option of the keypad.
My keypad is already plugged in when I turn on the mount and in EXT mode. I only want to have confirmation that APCC open, pointing and tracking correction disabled on it, I can do the initial keypad operations with my sky mapping software and enable tracking correction from the keypad by PntON.

New Solvers for APPM?

Bill Long
 

Hello,

Just curious if there has been any traction in getting new solvers added to APPM?

Thanks,

No problem, though this configuration is only for viewing, not imaging. 
This mount never ceases to amaze me with its capabilities and smooth performance.
This is not a permanent configuration in my observatory, but one that I mount occasionally.
I like the different width of field, visual views provided by each scope on a target. Adds context to the views, so to speak.
The two larger scopes are mounted on a dual saddle bar. Each of the smaller scopes is mounted on a bar on top of the bigger scope.

Re: Another Recommendation of the Ridgid Tool Cart for transporting the AP900/1100

M Hambrick
 

Hi John

Yes, the RA assembly just barely fit, and I forgot to mention that I had to cut back some of the reinforcing ribs in the lid of the box to allow the lid to close. I used a 1-inch layer of foam in the bottom of the box, and that made the mount base stick up just a little bit too much to close the lid.

I am still working on the Dec axis cart. I have been thinking about either putting the counterweight shaft in there, or (more likely) putting my cables, CP4, and Keypad.

Re: Another Recommendation of the Ridgid Tool Cart for transporting the AP900/1100

Well done on the Ridgid cases especially the foam cutting done for the RA assembly. Thinking is wouldn't fit
I didn't try the RA assembly into the 22" Tool Box, looks like it just makes it.

Will you store anything else besides the Dec. assembly in the Rolling Cart? Note, and I didn't realize this until later,
that the tool holder at the rear of the Cart is removeable.

Re: Meridian management

Joel Short
 

With SGP you don't have to worry about "minutes past meridian to flip"  SGP will never stop an exposure for something and will wait until the exposure is finished to issue a flip.  So in SGP just set your "Minutes past meridian to flip" to 0.  Let's say your exposures are 10min.  If the mount crosses the meridian at minute 2, the mount will track past the meridian for the remaining 8mins and after the exposure is complete SGP will issue the meridian flip.  Works perfectly and I've never done anything else.  
joel


Re: Meridian management

Marcelo Figueroa
 

What I do and it works perfectly well is to turn off the meridian limits in ACPP and let SGP take over. I usually use about 10 or 15 minutes past the meridian and ensure that the wait for meridian option is activated.
 


Re: Meridian management

KHursh
 

Thanks Andrea,

I am doing something slightly different, I think. I am trying to predict when the flip might occur so I can tell my imaging software what to do. APCC is set to flip at the meridian limits set in APCC, but that time will differ according to the DEC of the object I am imaging. You (I think) have already decided on a 45 minute delay, which is what I may ultimately do, but if my object is at a lowish declination I may not have to flip at all. I can play with my setup during the day and watch what it does at various declinations and write down when it approaches my limits (I should have done this when I set up my limits), but I am trying to ask if there is another way to predict the behavior


Re: Meridian management

Andrea Lucchetti
 

Hi Kevin, there is a similar thread from me about 1-2 weeks ago. I don’t comment here because I still have to practice what I have learnt. 
But if you are imaging with sgp I assume your problem is just to avoid loosing time at th meridian. If your frames are 600s, I think that a delay of 600s is enough to finish a frame and flip.


Meridian management

KHursh
 

I now have my Mach2 humming along pretty well. I have set up APPC Pro with horizons and meridians and a pointing and tracking model. Where I am stuck is with meridian behavior. I know that my mount can handle tracking past the meridian up to a point depending on where it is relative to my safety limits. My question is, with NINA or even SGPro, I have to tell the software, how long past the meridian to wait to flip so how do I predict this based on the Dec position of object I am imaging? Am I overthinking this? Should I just pick a relatively safe time, like 45 minutes, and flip there for all objects? TIA

Kevin


Another clear night for testing

Roland Christen
 

Howdy Astronuts,

We have had an unprecedented series of clear nights here due to a high pressure system that has stalled over the Midwest. Allowed me to do extensive testing of mounts and scopes this past week. High pressure means great transparency and also rapid cooling. This is what my 160 EDF refractor looked like last night around Midnight. Thick frost on the tube, the mount etc, but the lens remained clear. That dewshield really works, and that's without any sort of dew heater.

Hope to post a few snapshots of deep sky objects this weekend (just snapshots, nothing really good)

Rolando

Yes, keypads with serial number 1568 and higher can download the new software. The function of FOC and RA DEC REV buttons has changed in the new program, so the buttons on the current keypads are labeled differently.  You can simply use your current button pad and memorize the new functions or will have the opportunity to upgrade the button pad for an additional charge.

Re: Multi-star guiding

Terri Zittritsch
 

Your skies must be way better than mine, or the multi-star aspect of the Maxim guiding somehow average out the seeing across  the three stars for you.    I need to read up on this to understand how it takes advantage of the multiple stars and my guess is some kind of averaging which can filter out seeing to some extent. 
I just picked up a full frame 60mp ASI camera with filterwheel and OAG.    I plan to try the OAG but have had limited success in the past.  I do have a lodestar which is the guide camera I'd use with this kind of setup due to its sensitivity.     I really enjoy the flexibility and FOV fo the guidescope, but maybe I have some amount of error as a result of the differential flex.    The precision movement of the mach2 makes it a joy to use.
