Yes, I'm aware of the lower temperature limit but I rarely, if ever, image at that temperature. Here in the coastal mid-atlantic, things getting that cold happens only for a very short time during the winter and usually means that a front brought the cold air in, which translates to clouds anyway. Obviously it's a different kind of consideration, and an important one, for you up there in NH :)

Heating the battery box has been an idea I've toyed with recently. One of the things I'm considering are the catalytic hand warmers from Zippo. These small devices are meant to go in a pocket and produce heat by catalytic exothermic reaction of a liquid and a solid catalyst. Flame-free, not too hot, lasts 12 hours, and is refillable. It avoids having to use energy from the battery itself to keep it warm. I figure this and some rock wool insulation might do the trick. The thing I want to find out first is what the reaction products are.

Re: Tracking and guiding with and without encoders - Part2

Hi Chad,

Without encoders your mounts already guide up to the limit imposed by seeing. How much will encoders improve
the results of guided imaging?
I did lots of tests without encoders many years ago by turning PEC on and off. I could easily measure the difference in average FWHM of non-saturated stars. The reduction in FWHM was about 10% with 5-second autoguider exposures with a mount with 5-arc-second peak-peak periodic error. It is more dramatic with mounts with higher periodic error.

For example here is a comparison of actual star images taken with PEC enabled versus disabled and auto-guided with a mount with 40 arc-secs periodic error:

Without encoders your mounts already guide up to the limit imposed by seeing. How much will encoders improve
the results of guided imaging? No one is questioning whether encoder mounts track better or are superior for
unguided imaging.

A test like this would be helpful:

- Have encoders on, calibrate PHD2, use default PHD2 settings, set a 3 second guide interval, run 200-400
samples .... check the total RMS error

- Turn encoders off, have PEM disabled, recalibrate PHD2, default PHD2 settings, 3 second guide interval, run
200-400 samples .... check the total RMS error

Repeat the test a few times and compare. It would be best to use optimal PHD2 settings with both encoders on
and off. The above test would be simple and give at least some idea of the difference though.

Just to fill out that list, NINA also directly controls PHD2 through its event-base API and one can set a dithering op to happen at whichever interval is desired on a per-sequence entry basis. We even give the option of synchronized (or "cooperative") dithering between two or more instances of NINA and one instance of PHD2 for people who image using multiple cameras, such as on a side-by-side setup.

I can see by the graphs that these motors are constantly correcting and therefore working hard.  I'm located in BOILING HOT south Florida and expect to receive a Mach 2 in December if all goes well.  My question is simple...is there any concern about the motors overheating?  I also have solar telescopes so the daytime temperatures can get really hot.  Thoughts?  Sorry, I just worry about things getting too hot - experience!

Tracking and guiding with and without encoders - Part2

Roland Christen
 

Hello again,
Thanks for being patient in reading my previous post. You have earned a chocolate bar.
Below I have posted two graphs (I will post them also to our files section and soon to our web page).

The first one shows the difference when the Mach2 is running with encoders and without. The graph starts with encoders on, then I switch them off and run thru one complete worm cycle (about 6.4 minutes) and then turn the encoders back on. Although the tracking error with encoders off is only around 4 arc sec, you can see instantly which one you would rather have running in the background while guiding and imaging. Yes, you can guide out the majority of that error and yes you can even compensate most of it with PE correction (PEM), but do you really want to and will it be as accurate? My tests show that if the seeing is 0.1 arc sec rms, the mount will guide at 0.1 rms. It will not add little sniggles and snorts to the tracking that the guide software can't fully compensate for. If the seeing is 0.8 rms and your pixel scale is 3 arc sec per pixel, then you may not see any of these errors and your stars will be round regardless.

The second graph shows the response to outside commands which I sent at various intervals. In this case I sent 0.5 arc sec move commands similar to what a guide program would do. The mount will respond accurately to any size command from .05 arc sec on up. It can also follow a custom guide rate smoothly without steps.

Graph1:


Below is the tracking response to outside commands. In this test I sent 0.3 arc sec move commands at various intervals to the mount and measured the response, the actual shaft position after each command.Graph2:


Tracking and guiding with and without encoders

Roland Christen
 

Hello Astrofolks,

Much has been argued and discussed whether encoders are worth it for guided and unguided imaging. I want to present some data taken with the Mach2 (some of which also applies to the 1100 and 1600 encoder mounts).

Encoder discussion Part1 (Part 2 to follow in subsequent post):

The Mach1, 1100, 1600 and all the older non-encoder mounts used high grade Swiss DC servo motors from Maxon, which have integral encoders on the motor shafts. The motors are able to produce smooth clean tracking rates and the precision spur gears transfer that accuracy faithfully to the worm shaft. The worm then slowly rotates the worm wheel tooth by tooth to get the final output tracking of the RA axis. Although the motor shaft rotation is very accurate due to the shaft encoder, some very small errors get added by each mechanical component between that shaft and the final RA shaft. The worm wheel teeth themselves can develop tiny micro scratches during use that adds errors to the drive rate. Generally a new mount will have only a few arc seconds of error that can be compensated with PE correction in the PEM memory. Small scale errors that vary from tooth to tooth cannot be compensated but are generally reasonably small unless the gearwheel is damaged.

The servo motor, shaft encoder and precision spur gears are very costly items. They are audibly noisy and prone to backlash, which is a potential problem for Dec guiding. Although we made the gearbox backlash adjustable, in many cases the adjustment was difficult for our users and can easily be done wrong. Using the clutch on these mounts does not allow the controllers to keep up with manual movements, although it is easy enough to re-establish the home position if the mount position is lost via manual movement. Nevertheless it is an irritant to some people, and we wanted to address that in our new Mach2.

Mach2 encoder adventure begins:
Adding high precision absolute encoders to any mount is a costly venture. In the case of the Mach2 we developed a less expensive motor gearbox which uses a custom microstep servo motor and belt drive to replace the Swiss DC servo motor, encoder and spur gears. This partially offset the added expense of the precision absolute encoders. We also completely redesigned the clutch system so that the encoder not only reads the rotation of the worm wheel, but always reads the shaft position. This adds cost to the mount which we could have left out by doing away with the clutch altogether (like competing mounts), but then for balancing you would have to disengage the worm teeth to allow the shafts to rotate - and this can be potentially fatal to the worm teeth if done wrong. Our clutch allows disengagement of the shaft while keeping the worms always fully engaged. No chance for tooth damage. You can also disengage the clutch and move the mount manually for sweeping the sky at leisure and never lose your position.

Although the use of belt driven microsteppers sounds like a vast improvement over DC servo drives with their audibly noisy spur gears, the tracking accuracy of the raw microsteppers is not as good. If you don't use precision shaft encoders the microsteppers add their own rotation errors and the belt pulleys add small cogging errors as well as stretch and delays during reversals. These add up to a more ragged tracking rate than you would get with the DC servos.

Temperature changes also have impacts on belts, none of which can be fully eliminated with PE compensation. Somewhere along the line you have to add an encoder, either 1) on the end of the motor shaft, or 2) on the driving worm, or ideally 3) on the output shaft itself. Numbers 1 and 2 are inexpensive but don't fully accomplish precision tracking. Number 3 is the most expensive but has to be done right in order to produce stable, precise and effective tracking and positioning. The encoder loop has to be stable in order to allow external guide commands to position the guide star as close to the zero point as possible, within the constraints of the atmosphere, of course. And that's with wildly varying loads, moment arms - without oscillation instability, overshoot, delay, using various guide software that have their own quirks.

Part 2 will follow

Lately we are trying out SkyX imaging/guiding software as an alternative to Maxim. So far with limited success, but probably because of the steep learning curve. I'm most comfortable with MaximDL because I've used it for so many years.

Hello, I just purchased an AP1100 AEL and have been using MaximDL 6.2 for image acquisition and guiding. I was wondering what most people use for guiding with their AP AE mounts? I have been using MaximDL on my non-AP mount because it can dither. I'd prefer to use PHD but dithering with MaximDL is more difficult and haven't figured out how to do it. 

One of the issues I had with my non-AP mount was the dithering recovery time took a few minutes, I never could figure out how to make it quicker. I don't foresee this to be a problem with the AP mount..

In any case this is a question about what software you use for guiding the AP 1100 with AE and why?

Thanks in advance

The internal wiring harness was a mix of wiring made by myself (anything that involved PowerPole or Quick Disconnect/Faston connectors.) For things that involved ring terminals, such as connections to the binding posts and the battery itself, I just had Powerwerx make them for me. All internal main wiring is 10AWG, with the connections between the rocker switch and the USB+ciggy lighter port being 14AWG.

Tools used:
1. Dremel with cutting wheel and small deburring bit to cut holes in the case top
2. 1/2" drill bit for drilling the holes for the binding posts
3. Utility and xacto knife for trimming plastic bits where needed
4. PowerPole and QD/Faston crimper
5. Wire cutter/stripper
6. Needle-nose pliers to get the QD/Faston connectors onto terminals
7. Lots of patience

Re: Using the GTO keypad with the Mach2

Great idea! I would also like to have one you could read in the daytime.
Right now I have to cover up my head with a black-out cloth.

I hear you. We actually are thinking of adding a minimalist keypad with Oleg screen that shows up in the daytime. One of our customers developed one and it is really nice. We just have to work out some things, but like you i do want this also.

Rolando, I don't mean to start anything, but most imagers have their mount connected to a PC and therefore don't need the keypad - at least at night. What we do need is a keypad we can see during the day when we're doing maintenance stuff. Your keypad is great but only at night. During the day it's a real pain. Every time I'm forced to use it I keep thinking of the easy to read in the daylight keypad on the cheap mount I use for visual stuff. Will we ever see an AP keypad usable during the day?

Nothing has changed on the keypad physically. Some of the buttons may change function. We don't have a final software set yet. We are adding in some things that will be very useful to imagers.

That is GREAT news. I sure hope it works out.
