New AP900GTO CP2 Owner looking for a used CP3

Jim Johnston
 

New to the group and new owner of a used AP900GTO CP2 mount.

Am now looking for a used CP3 V, V1, or V2 in order to use APCC.

Anyone able to help a fellow out?

Re: Do NOT use ASCOM Platform v. 6.5 with APCC Pro #APCC #ASCOM_V2_Driver

Hi Andrew,

If you could provide an update on when this issue will be
fixed that would be great.
Actually, I reported on this a couple of weeks ago. ASCOM 6.5 Service Pack 1 will fix the bug (which is in ASCOM, not APCC).

However, if you want to try the beta version of ASCOM 6.5 SP1, which I have tested and confirmed has the fix, then here is the link:

Hi Howard.

I spent half the night trying to create a new APPM model using ASCOM 6.5 and getting the same plate solve
results for every image. I was about to post the issue here, when I saw your post. Any eta on when this issue will
be resolved? I am kind of caught in a catch-22 at the moment as the latest version of SGP and other software I
am using to control my rig now requires ASCOM 6.5. If you could provide an update on when this issue will be
fixed that would be great.

Re: How do I diagnose a motor stall? #APCC

Roland Christen
 

You might want to increase your voltage to 16 or even 18 volts. Turning the slew speed down to 900x will also help.

Subject: [ap-gto] How do I diagnose a motor stall? #APCC

Last night it was the first sub-freezing night we have had this year. I was imaging in the observatory and this morning I found the Mach1 parked in place with APCC displaying an error indicating a motor stall. Upon inspection of the SGP log, the imaging run had completed and a park mount command had been issued, the ASCOM driver reported back that the mount had been parked, albeit not at Park 3 postion. How do I diagnose what happened? I am wondering if it is simply that I should back off the slew rate to 900x for the Winter or if it is an indication that the mount needs to be regreased. I am attaching a link to the zipped log file and a screen shot.

Thanks!

Thank you for the quick reply and update! I can imagine the backlog at manufacturing services like anodizing, heat treating, etc... from Covid. Honestly I would of guessed you would have in-house anodizing, then again it is messy. I remember no-so fondly of doing plating when I worked in tool & die many years ago.

Machining is pretty much finished for the first half of the run. Finishing is proceeding now but anodizing is slowing us down (subcontractor backlogged due to Covid). We're estimating that the first mounts of this run will go out in December.

Can any of the A-P folks give an update where the 1100GTO are at in production or is still mostly the Mach2GTO?

Thanks and appreciate the focus on quality over quantity!

Yes indeed, most L filters filter ou UV and IR. See some measurements here :

Re: UV-IR Filters in Front of R, G and B Filters

RGB filters automatically block all UV, so adding another doesn't do anything. Secondly, adding any flat piece of glass before any filter will set up multiple reflections between the two glass surfaces which will result in multiple faint halos that are not centered on the star, and will probably show up nicely around every bright star. It's like being in a hall of mirrors and seeing yourself multiple times off into infinity.

I recall reading somewhere (maybe Ron Wodaski's book  "The New CCD Astronomy") that some imagers have a common UV-IR filter in their imaging train so that even when they are imaging through the Red, Green, or Blue filters, they are also filtering with the UV-IR to block out light pollution. Is there anyone doing this ?

I only see VCP4-P01-14 on the AP website, where can we get P02-06?

Hello Brent
 
Fantastic!
 
Many members want to track the ISS via ascom.
I still prefer the older legacy LX200 direct connect (no ascom).
 
Your new Skytrack software (presently leap-frogging via ascom) available at
 
 
The reason I purchased a new 900GTO back in 2011 was because the 900GTO allows me to track the ISS from
 SW horizon to zenith to NE horizon with no meridian flip (just when the ISS is closest).
 
When you add variable rate via ascom along with your already available re-centering controls,
We will have many ISS pass movies with these fantastic Astro-Physics scopes and mounts.
 
I'm a happy camper.
 
Jimmy
My ISS passes from backyard with your older SatelliteTracker software v2.51
33.6N, 88.6W
 
The gravity field at the ISS (250 miles up) is still about 89% of
 what it is here on the surface of Earth. 
The ISS moving at 5 miles per second (18,000 mph) wants to move in a
 straight line tangent to it's orbit and
 away from the center of the Earth.
Gravity pushes the ISS towards the center
 of the Earth an equal amount resulting
in a continuous free-fall orbit around the Earth.
If the ISS slows down it will return to Earth and burn up in
 the atmosphere. (5000 degrees)
If the ISS speeds up, it will move to a higher orbit and
 at about 7 miles per second (25,000 mph) will reach
 escape velocity and no longer in orbit around the Earth.

Re: Satellite Tracking

Dean Jacobsen
 

Welcome to the group Brent. 

I will definitely be following your progress on your satellite tracking interface.

The software bundle that comes with the Mach2 contains a program called Astro-Physics Horizons.  If you haven't seen it yet, here is a link to Ray's help files for APCC and the Horizons program is at the bottom of the table of contents.

https://www.siriusimaging.com/Help/APCC/index.html

I haven't yet actually attempted any tracking with the AP Horizons program yet.  I have been just doing manual tracking of the handful of FM AMSATS that my FM UHF/VHF radios allow me to contact.  I need to upgrade my radios to be SSB capable on the UHF and VHF bands that the AMSATS with linear transponders operate.  However, based on my manual tracking, I am convinced that the Mach2 is plenty fast to track the satellites that I am interested in.

Anyway, I hope to be able to at least try out the AP Horizons program on a favorable ISS pass and video the pass this next new moon cycle when I am set up out at our club's dark sky site.

Yes, I guess the tricky part would be at the point that the object passes the meridian and dealing with a mount flip.  However, passes for my objects are frequently on one side of the meridian for most of the pass.  So I guess I will find out how that detail is handled in the AP Horizons program.  :-)
