That is about what I am doing with my all sky models Ray   - between 45 and 50 - with my short focal length setup and small pixel setup.  Most of my imaging is done at either 530 mm [~1.5 arc sec/pixel]  or at about 380 mm [`2.05 arc sec/pixel].

My images are only 240 sec. max though.

APPM plate solves using SGP and PS2 only take one or two seconds each.  Only occasionally do I run into a long solve and it is a rare occasion that I get a failed solve.  So APPM runs pretty fast on my laptop.

1600 Worm Damage?

Mike Shade
 

A couple of questions...in PemPro, what would a damaged first generation 1600GTO RA worm look like, in the data?  Is there a way to tell?  What about tracking?

 

If it is suspected that the worm is damaged, is there a solution? 

 

I would really like to replace with the newest "self adjusting" gearboxes, is this possible, regardless of potential damage.

 

Greasing with scope pointed north over mount, some wind and a inattentive helper...not a good day.

That really depends more on the scope you are using vs the modeling software and encoder system. On a refractor you can get extremely long subs with a very small model. On an SCT you can build very large models if you desire but the nature of those scopes can limit the exposure length on their own.

I personally use an 82 point model for all of my imaging. That seems to work perfectly well for me. The only problem I encounter is the lag in plate solving due to APPM not supporting lighter weight plate solving solutions like ASTAP or PS2.

It depends on the equipment you are using, especially repeatability.

With only 42 points last night I was able to get 30-minute unguided images in several different sections of the sky with just a pixel or so trailing with my A-P Traveler and STT-8300.

I'm waiting for a couple adapters from Precise Parts to push the limits since the STT-8300 I recently bought on Astromart has a full set of narrowband filters. My San Jose skies would blow out my unfiltered images in 30 minutes, so that limited the duration that I could test.

I suspect that the answer would depend on the focal length or pixel scale that you are imaging at.

If the object is on Dec 60, then opposing dec lines would be 50 and 70.

However, if you are using APCC Pro (APPM) then just do an automated all-sky model. Doesn't take long.

Sorry ... I pushed Reply before typing out my question for Roland and/or other unguided imagers:

Given Roland's scenario of M52/Bubble, these "opposing Dec lines" would be what exactly?

I'm looking to replicate your quick point data modelling for my non-permanent 1100GTOAE setup with APCC/APPM.

I took quick pointing data of 5 stars each on opposing Dec lines instead of taking data along the object's path. This way the modeling program could better calculate orthogonal errors, polar alignment error, scope flexure, as well as the drift error due to atmospheric refraction.

Re: New Mach2 Problem

Ray Gralak
 

Hi Roland/Larry,

I powered up my Mach2 last night for the first time and connected it to latest APCC and V2 driver.
It goes to all of the park positions fine except Home.
On APCC's "Park" tab, parking to the Home position was trying to use the mount's internal, non-encoder home position, and not the Mach2's hardware home command.

This will be fixed in the next build of APCC Pro, which should be v1.8.8.1. (It's not available yet, so don't look for it.)

For now, if you want the Mach2 to go to the home position, use the "Find Home" button on the "AE" tab in APCC.

$HA# is the fundamental command to send the Mach2 home and do a recal. It is the command that would be sent by
any app that knows how to communicate with the mount. The latest version of APCC Pro sends this command when
you press the HOME button. If all else fails, you can input this command yourself and send the mount home, recover
the proper alignment and thus recover from an errant sync.

This is useful information to have but I searched the APCC manual, the Mach2 manual and the GTOCP3 manual and
couldn't find any reference to "$HA#".

Is it discussed in the manuals?
