Basically you get one data point in about 200 seconds (3 - 4 minutes) which sets the drift rate at that point int he sky. So that will work for a while, maybe 1/2 hour to an hour, after which the drift will have changed. So then you take another 3-4 minute run to establish a new drift rate. You do that every hour or so along the path that the object takes.

That's exactly what I'm doing also. 3 - 5 minute drift measurement which is good for an hour. However, if I take just 3 drift measurements along the path, spread out over a 5 - 6 hour period, the CP5 will then compute a continuously variable tracking rate for all points in between for the entire 6 hour period. I can do this measurement all at once before the sun goes down using 3 widely spaced stars of Mag4 or brighter and an H-a filter.  Takes about 15 minutes total. This path is then computed and ready to go when twilight ends. I can even do another object path at a different Dec, download it and be ready to image two objects. In fact, if the two Dec lines are widely spaced, I can image all objects in between also unguided because the model computes the variable tracking rates for the entire sky area as well as +- 10 degrees outside those two Dec lines.

Below see the tracking graphs for the imaging that I am doing tonight. They show how the tracking rates vary over approx 45 minutes.

That comment has to do with a long-time on-line chess game, not for you/forum. Sorry, it's wrong context, I've a busy day on email today.

In reply to your own query, you set up each object separately. I use the Autosave feature on Maxim and when finished with one object, move to it, train ATrack, an make the second one. It's that simple. The User Guide is a good start and will answer your queries without reference to chess moves. 😉

That's right. I'm using this thru ASCOM, you can use SkyX also, and MaximDL. You just need to set up a
'Watch Folder' for your images, ATrack and PinPoint do the rest. You can save your config profile for next time
if you like, or not, whatever you prefer.

It appears that ATrack doesn't actually take any images or control cameras, it just monitors a folder for new
images. Is that
correct?

So, which software package are you using to set up taking training images and your science images?

I know at first glance this might seem complex but it is actually very quick and easy to do and it works very
well. I am not an expert, but with less effort than a few minutes using ATrack it gives me excellent images

with

little to no fuss, something I've been struggling with for years with good autoguiding programs, and it works
every time, very robust. This is not an autoguiding program, it requires a very slightly modified mind-set,

that's

all. I can speak from experience that it is simple and it works well and I now have no need at all to go back to
autoguiding. Set-up is minor and the software doesn't use the PC registry, thus quick set-up and use. Read

thru

the book, takes five minutes to see how to set it up. Calibration takes less time and effort than any

autoguiding

software.

ATrack can use each subsequent science image to monitor how things are going and re-center as
necessary thereby avoiding accumulative errors. This can work in parallel with an AP model. The

methodology

uses a plate solve of each image and gets information from each previous image. It is very effective.


Here's a 10 minute (not autoguided) image I made with ATrack a couple of days ago - 3% AR, using
1100GTO, no AE, TEC140 on the QHY9 cam. There are many more, and they're easy to obtain using this
software.

Technically, it is closed loop tracking (auto-guiding) since it using feedback from images to adjust tracking.

Also, it looks like there is some setup required to create a script or configure the training images for each
target. Which software
package are you using to do that?

The 20 second images are "training" images used by ATrack to determine the drift - just like the
calibration images in PHD and Maxim, etc. You can use 5 second images, or as many or as long as you

want.

And you can space them out however you like. For example, you can make 10 x 5 second images with a 1
minute gap between each. Or you can make 2 x 20 second images with a 5 minute gap between each.

Ideally

though, the best is a sequence of 10 x 20 second consecutive images. The reason is because 20 seconds
tends to smooth out seeing conditions. 10 images provides enough data to derive a good average of the

drift.

The more points the better. So it is up to the user to define what is best for the ATrack training sequence.

And

after that you begin your 5 or 10 minute science images, or whatever lengths you like.


Typically, the drift rate of a telescope does not change terribly much in 10 minutes. Since ATrack sets
the motors properly, it'll be fine. Obviously, if the seeing changes or something in the system 'jumps' the

scope

(think "PE", or a physical bump), then it won't work properly, in that case, just re-train. You can insert a

training

sequence prior to each 10 minute image if you want to ensure that it has the best rates set in the mount

before

starting.

some

of

the larger inexpensive truss tube scopes. If one is using a solid refractor the all-sky model that APCC Pro
creates will give excellent results throughout the sky. I've posted images up to 30 minutes unguided at
1.74"/pixel with round stars.

Thanks Don, it's easy to use and I've been getting aspect ratios of around 2% to 6% regularly. This is
unprecedented with me. I set it up and go to sleep. Enjoy!

Steve

PS: The plate solve is very useful and helpful in getting accuracy - to the pixel.

Thanks, Steven.

Here's a link to the manual.

ATrack (Adaptive Tracking) has been around for a year doing the same thing and recently I

have

switched to it for unguided imaging. So if anyone wants to use ATrack while waiting for AP to add the

software

to APCC then they should contact Craig Young at Crystal Lake Observatory. The use of PinPoint is

requierd,

and that's easy.

Roland, this looks exciting, any ETA for release?

This seems like a great feature for us mobile (non fixed installation) users. Given how easy and

fast

this is, 5 minutes/hour of object tracking, will this be usable if you also have a PC connected (for things

like

plate solving) and do you use it with, or instead of, APCC?
