Don, Ray, thanks for your continuing advice. Soon as it stops raining I'll go at it again.  I use a single monitor, but the warning window might have popped up under something else. I have seen it before.

Thx, Bob

Yes, that would be great. At high magnifications it is required to have additional relative corrections on top of the tracking. Maybe these corrections could even come from a guiding tool (like Firecapture centering a planet).

Thanks & Clear Skies,

Re: Slide Rules and Slipsticks - in the 1960's B.C. - i.e. (Before Computers)

weems@...
 

Through most of middle and high school I used a circular slide rule. In senior year I used money from my grocery store job to buy an HP45. When I got to engineering school, one professor insisted that pocket calculators were a fad, that circular rules were not good enough, and that I had to buy a straight rule. The local engineering supply had, for a while, taken top-quality rules in trade for calculators. So I was able to pick up a used Dietzgen 1734, with a mahogany core and teflon bearings, very cheaply. I still use it in my CS classes, as an example of 0th generation computing technology. It is still in its orange box and leather holster, with the manual wrapped around it. 

Early computers I've used and/or programmed include: IBM 360/20, 360/40, 1130, 1620, PDP 8/L, 8/E, 8/I, 12, VAX 11/780, CDC 3300, Cyber 74, Cyber 180. Also a research machine using a glass delay line associative memory in combination with surplus core memory units from the IBM 7030 (I still have some of the core planes, drivers, and manuals). The 3300 had the coolest console of any of them, with rows of projected octal digits. The research machine had the weirdest instruction (skip on sunny Sundays).

Re: APCC model like Mach2

skester@...
 

Am I correct that this feature is the same functionality Roland used via the keypad on the Mach2 to build a model only along the path of the target to be imaged?  If so that sounds like a big win for mobile imagers like myself.

In the "cleaning up" domain.... Back in October during the Mars

noise and sharpens images. <https://www.topazlabs.com/denoise-ai>

It works really great! I've attached a slit-screen grab showing a
portion of your image and a preview of what it would look like after
DeNoise AI did its magic.

Your image doesn't have much noise to start with, but DeNoise AI would
have slightly sharpened it and brought out a bit more detail. I've seen
it remove a LOT of noise in some of my images, and it always improves
the details.

It greatly improved my pathetic Mars images last fall.

Topaz Labs also sells Gigapixel AI to resize images, and Sharpen AI to
sharpen them. I have Gigapixel, but don't use it much because it takes a
LONG time. Just reducing a 4500x3500 image to 800x600 takes 10-15
minutes! I suspect it runs faster on "normal" (non-astro) photos.

Sharpen AI appears to be a new product, and I don't know anything more
than what's on the website.

Clear skies.

The pop up warning window may be off your monitor. Do you have a dual monitor setup? Sometimes if you happen to be using only one of the screens in a dual monitor setup, some pop ups won’t show because windows is still trying to place them on the inactive screen. I had that problem in Maxim.
The park features in the driver have always been there and have worked.
Stick with it you will get it figured out😁

Nothing should happen immediately because a popup window should show a warning that you should not use Park 1. Parking won't start unless you accept that window.

If you didn't see that warning window then maybe it popped up in an area of the screen where you didn't notice it, or the park button was not fully clicked.

Until this morning when I installed the new AP driver, TheSky included setting tracking rates and parking in
positions 1, 2, or 3 in its Telescope/Options menu. To my surprise, these options disappeared after installing the
new AP driver. All I see there now, as Don notes below, are Focus Control and Slew, for which I have no need.

Re: ISS Tracking with APCC & Horizons plus using handbox buttons ??

Ray Gralak
 

During the tracking I tried to use the hand-paddle buttons to superimpose correction onto
the tracking trying to
keep the ISS in the camera view screen. It somehow worked a bit but I had the feeling that the tracking was
'fighting' me back. Once I pushed a button to move the ISS to the center 'something' pushed it back by a bit
moments later. I got some success by over-compensating and ISS got then back (closer) to center. At one point in
this effort however it got lost outside the view finder screen and never came back.
Horizons continuously slews to new RA/Dec coordinates, so the A-P mount hand controller moves probably won't have much of an effect. The drift could be from changes in the orbit of ISS. In a future version of Horizons, I'll try to work in a way to detect relative moves and add them in.

Hello All,

Alas, a recent ISS passage and the ISS tracking questions pour in. :-)

I guess this is for Ray. Tracking ISS yesterday with APCC / Horizons / AP1200 worked reasonably well.

Question:


* What is happening there?
* Is it a correct expectation to operate the hand paddle buttons independent from the APCC tracking? (My
thinking is that the APCC uses custom tracking rate which is something different from what the buttons do). Is that
assumption correct?
* Really cool would be to have a USB access to a PC 'gaming' joystick and use that to move the mount. Any
ideas in the AP mount driver to support that?


As always great shout-out to Ray for the excellent work he does!

Re: Tracking ISS with Horizons #APCC #Mach2GTO

Ray Gralak
 

Now, look at the second image. The values in arc-sec/hr are roughly the same,
but the values in arc-sec/sec are
more than an order of magnitude different. Am I missing something here?
It could be a typo in the units. Remember that one RA sec/sec is 15 arc-sec/sec. I'll fix that in the next build, but it should not affect the tracking.

Okay, I’ve been playing around with this, both using the Test Tracking and in real-time, albeit in my basement due
to the clouds, and I am learning how this works, but I do have one relatively simple question.

Tonight I did a run in real-time and also using Test Tracking. The numbers in Test Tracking puzzle me.. The first
image shows the screen during the real-time run. Note the values for RA and Dec rates, in arc-sec/sec and arc-
sec/hour. Both rates show as roughly comparable for both units (arc-sec/sec and arc-sec/hr).



Now, look at the second image. The values in arc-sec/hr are roughly the same, but the values in arc-sec/sec are
more than an order of magnitude different. Am I missing something here?



Thanks.

Re: Pier for 1100GTO #Guiding

M Hambrick
 

I use my 1992 vintage A-P portable 8-inch pier with my 1100GTO mount. It is rock solid, even with a 180 EDT scope, 16 megapixel camera, and piggybacked guide scope attached. I set up and take down my gear including the pier every time I get it out.

I didn't anchor my pier in concrete, but I did pour 8-inch diameter concrete pads about 2 ft deep into the ground to give the pier legs a solid base to sit on. if I had a permanent observatory I would try to figure out a way to lock the legs into position so as not to disturb the polar alignment.

The biggest challenge I had with my old A-P pier was getting the 1100 mount base firmly attached to it. The top of the original pier was not perfectly flat, so I had to hand scrape the high spots so that the mount base made even contact with the top of the pier. The old piers only have three holes for attaching the mount base. I drilled three additional holes in it so that I could attach the mount to the pier using all six screws. Finally, I use NORD-LOCK lock washers on the screws that attach the mount base to the pier to prevent the base from shifting in the pier when everything is attached.

I hope this information is useful.

Mike

I did call up the driver window, set Park 1 down in the lower left corner and clicked OK. Nothing happened.

Re: Pier for 1100GTO #Guiding

My understanding is that the diameter is more significant than the thickness of the tube. Why not just pour a 12” diameter concrete pier with a Dan’s pier plate and AP adapter? That would be stiffer than an 8” tube, and less expensive than a whole new metal pier.
