AP1100 GTO question

Shailesh Trivedi
 

I recently purchased an AP1100 from a user who got it from AP in the April batch (thanks to Astromart). This comes with the Losmandy HD tripod. I am expecting the mount (+ cws) next week.

I am also about to get a TEC 180FL next week (it has been shipped by Yuri), so I am excited to give the AP1100 a spin.

I am new to AP mounts and this one does not have AE, and comes with APCC (not pro), I have a Paramount MX and associated The SkyX with Tpoint etc.

I have three questions:

1. Can I use Tpoint from Software Bisque to create a pointing model for the AP1100 or do I need to upgrade to APCCPro?
2. Will the Losmandy HD tripod be able to handle the TEC 180FL on the AP1100? (38lbs scope + about 15lb cameras accessories + the mount ofcourse).
3. Is there a way I can mount the AP1100 on a Paramount MX permanent pier via an adapter?

How much else will you be adding to the scope? guide scope, camera, other peripherals?

Subject: [ap-gto] #Mach2GTO - Can It Handle TEC 180FL?

I know many had suggested that the 1100gto to be the best candidate for the TEC 180FL refractor. However, I have checked AP’s website spec sheet for Mach2GTO mount and it does look like the TEC 180FL is within range - both in weight & dimension. I’m not really a big fan of mount overkill idea nor ready to drop $15k for a mount. So, my question is, can the MACH2GTO handle TEC 180FL at ease without any concern for longterm effect/issue? Per TEC’s website, the 180FL OTA should be very close to 40 pounds.

In some cases the length is more important than the weight.
 
Example:
 
Need a broomstick or something light, strong and a few feet long
Put a 10 or 20 pound counter weight on a horizontal broomstick so you can slide weigh close to you.
Hold arms out horizontal holding broomstick level with ground and counter weight close to hands.
 
Notice the torque on your shoulders to keep broomstick level with ground.
 
Slide counter weight out a foot from your hands
 
Notice the torque on your shoulders has increased to keep broomstick level with ground.
 
Slide counter weight out another foot from your hands
 
Notice the torque on your shoulders has increased to keep broomstick level with ground.
 
If the weight is too large or the distance from shoulders to weight is too long,
 you will eventually not be able to keep the broomstick and weight level with the ground.
The Torque on your shoulders is too much for your shoulders' muscles.
 
In this example your shoulders are your mounts' worm and worm-wheel.
 
Torque is a static and linear force and zeroed out if balanced.
 
Moment of Inertia (resistance to change in speed or direction) varies with
the distance squared from worm.
 
Length of scope can be more important than the weight of scope.

As always I may be wrong again.

Re: SatelliteTracker is now SkyTrack

I have not tried SkyTrack.
SkyTrack has a 30 day free trial then $9 one time.

https://www.heavenscape.com/index.html

SkyTrack says it has variable speed tracking available with Ascom.
If SkyTrack's Ascom variable speed tracking works with Astro-Physics mounts
 then that sound very promising.
 
Most of my ISS movies were recorded with the original SatelliteTracker v2.51 direct connect with no Ascom.
First movie was hand guided.
 
Recently cleaned mirrors on my home assembled 10'' Newtonian f4.5 and have been slow to reassemble.
 
I select ''LX200 Compatible interface'' in v2.51 to connect to my 900GTO.

The 900GTO has 0 problems tracking through zenith.
 My cheaper mount can't track fast enough, leap-frogs through zenith and
 then a meridian flip at the worst time when the ISS is closest.
 
 With the 900GTO I set the meridian flip point to the western horizon and
 can track SW horizon-zenith-NE horizon with no meridian flip.
 Starting with scope upside down and pointing at SW horizon.
 
 The meridian delay option is why I purchased my 900GTO back in 2011.
 
I know some members want to record the ISS and see those gaps between the solar panels.
I do hope SkyTrack works with Ascom and Astro-Physics mounts.
 
Show us your gaps!
 
Looking forward to seeing more pictures and movies of the ISS with Astro-Physics Scopes.
 
Note:
Most of the night passes are invisible due to ISS in the shadow of Earth before it gets to my backyard.
 
All daylight passes over my backyard are visible and brighter due to EarthShine.
 
If I have good polar alignment and find the ISS in daylight,
 the 900GTO easily keeps the ISS on screen with Joystick in a 17x13 arc-min FOV.

Hi Jimmy

Most impressed with your space station shots, really good work. I spent a few years with analysis of high speed tracking cameras in Woomera Australia for missile tracking. In those days a computer was blonde or brunette, yes they were ladies using Comptometers for data reduction.

Current setup is AP1200 with AP178 or AP130 visual work, was thinking to use the APCC as my computer is a Mac. Do have a fairly old windows XP machine and was thinking to try Skytrack before going down the path of APCC Pro.
With your experience do you have comments on this approach.

Kind regards Mike

With a bright moon and clear skies, I spent the July 1-2 evening drift aligning at a remote Wisconsin state park site to accurately configure the RAPAS with the Mach2. This was the first time I had the C925 and guide scope in the field on the Mach2. My guide scope of choice is actually a 25-year-old Nikon 300mm f/4 ED lens.

Also, I was able to use Sky Safari via WiFi to run the mount in conjunction with TheSky running the Mach2 on a laptop via RS-232. This worked long as I connected to and initialized the mount via RS-232 and APCC first.

While waiting for the hand controller to be shipped, it was a big help for me to have the Sky Safari  app to nudge the drift star back onto the crosshairs by using my iPhone. That green streak of light under the telescope is a firefly trail.

When I upgraded earlier this year all my settings from APCC standard were carried over to the Pro version.  Installation was straight forward.

Re: Has Notification Started?

Karen Christen
 

Hello Larry and all,

We have not yet started the notification for the second run of Mach2s.  At present we are focused on making final edits to the Mach2 manual, updating the Keypad manual with a variety of new functions, taking orders for a run of 130GTX scopes, and assembling and shipping the last few mounts in the first Mach2 run.  Fear not, however, as mount-making progresses.  Since June 1 our production staff has been hard at work moving the second run through the process so delivery of these mounts will be delayed only by the 10-week Illinois coronavirus shutdown.  To answer a question that was floating out there recently – all first-run Mach2s were offered to people on the old Mach1 list.  We have not yet started on the Mach2 list that begins 4/4/2019. 

We love and appreciate your anticipation.  Please hang in there.

Marge, the first of June you said that you expected to begin notification for the next production run of Mach2's later in June.  Has that started?  The reason I ask is I thought I was close to the top of this list and if you had started notification and since I have not heard anything then perhaps I am not as high on the list as I had hoped.

Writing back just to close the thread on the resolution of my issue. I've found a solution but just reporting back to minimize the rebuilding of wheels for anyone else is having issues.

I picked one of the images that Platesolve2 wouldn't solve during the APPM run the other night and loaded it into different programs. 

1. Astrometry.net (nova.astrometry.net) - image solved 
2. Stand alone version of ASTAP - solved in less than a second
3. Stand alone version of PlateSolve2 - solved in a bit over a second
4. Opening the image in SGPro with ASTAP solving (right click on image) - solved, about a second
5. Opening the image in SGPro with Platesolve2 solving - solve failed

I created a profile in SGPro using ASTAP as the default plate solver for APPM and the mapping run completed in nearly half the time needed when using PlateSolve2.

The same folder as the logs. BTW, when APPM is collecting data if the image has been saved you can double-click the failed line in APPM and the FITS image will be opened in the default FITS viewer on your computer.

Usually full-frame results in better accuracy than 1/2 or 1/4 in my setup, but I'm not sure if that is universal. Using 1/2 or 1/4 center may or may not speed up plate solving as there might be 4x or 16x as many spiral plate solve attempts, and the max solve count for PlateSolve2 may be reached sooner.

I used platesolve2 for a long time as my plate solver in SGP.  As a result of a forum discussion (here as I remember)  about using ASTAP, I have switched to ASTAP (it was easy) and found that I can plate solve much faster and I think it works very well with APPM, returning points faster.    I like it better than platesolve2.   Consider switching to ASTAP if it seems slow with platesolve2.

Thanks for the post Greg, I should have started reading at the bottom.   Someone else recommended ASTAP and I think I need to finally try it.   
I usually get solves on the first plate in platesolve2, after my first solve, but still it's slow.   I find that during normal imaging, the whole efficiency with SGPro and my ASI camera seems to be a lot less than optimal.. I seem to loose a lot to overhead with an ASI1600 camera.

Ray, have you tried using SGPro and platesolve2?   I did not get 2-3 points per minute.  I was maybe getting 1 per minute average.   This accounted for the fact that some points (maybe meridian) needed to be solved multiple times (twice only I think).   So while each solve likely took less than a minute, with the central points that needed to be solved twice, it averaged out to 1 per minute.   
 I always shoot at 1X, but have do have usb3 download.  One of these days I'll try binning, but I've never thought binning on a CMOS camera did anything at the camera for efficiency.
