How do you connect to the mount...wireless, wired, RS232?   I wonder if the IP address has inadvertently changed?

Thanks Roberto,

Voyager is the obvious alternative - how does it handle scheduling of multiple targets over multiple nights with weather interruptions? Our observatory operates autonomously, so I’m after something that schedules observations from a list of tasks depending on what is best placed in the sky.

Others will reply on INDI, but have a look at Voyager Array: https://software.starkeeper.it/

I have two AP mounts - only one imaging though - but also two telescopes running in tandem and imaging in my RoR. Voyager handles all the observatory functions from start to finish and it’s super stable.

Re: Issue with starting ASCOM driver from SGP #ASCOM_V2_Driver

Sorry not to reply early. Been cloudy and not used the mount!

Neither APCC nor SGP were run as admin, and Auto-Config was already checked.

Same behaviour. It will not start the driver when connecting from SGP nor from any other client (e.g. StellariumScope).

But the driver starts fine if connected first from APCC.

Note: clicking on Now for Auto-Config in APCC claims to successfully update the driver config, and yet the problem persists after that


A query about AP mounts / APCC & Indi #APCC

David Trappett
 

First of all, I'd like to start by saying I don't want to stir up a hornets nest with this post,

I manage a school observatory in Australia.   We have two AP1100 mounts, connected via APCC/ASCOM to ACP Scheduler for autonomous remote operation.

I'm getting a little frustrated with the ACP issues that frequently occur with Windows 10 updates - not trying to point fingers at either provider being at fault BTW.

I'm starting to investigate alternate software options to run the observatory autonomously.    I've spent the last few days investigating EKOS Scheduler and it looks promising.    I plan to try it out with my personal equipment over the next few months (although I'm yet to see if my Mach1 GTOCP3 with Firmware Q will connect with INDI)

The obvious sticking point for the observatory 1100s is an INDI driver that provides the same level of protection we are afforded by running our mounts through APCC.

I've read through some posts on this forum, dating back 1 - 2 years that mentioned something was in the pipeline.    I don't want to change the system over tomorrow, but can you give any sort of timeframe for a comparable option to be available for INDI?

Regards,
DT

Imaged with the 160EDF refractor on the Mach2 mount. The comet head was tracked using the Keypad Drift Model. I took one data point on the comet's nucleus (a 4 minute drift measurement), then turned on the Model to begin tracking the comet. I took a total of 40 images of 30 sec each thru LRGB filters over a period of about 1/2 hour until the comet dropped below my observatory walls. The background stars moved approximately 1/2 way across the frame during that time while the comet stayed stationary on the chip. Seeing was good but transparency was unfortunately poor with thin high clouds.

Tracking comets can be done two ways, with APCC Horizons and now with the keypad custom model. Using Horizons with emphemeris data takes a bit of doing, and is suited for permanent setups. The keypad drift model is very quick and quite accurate and can be done in a field setup in just minutes.

Re: Comet Neowise

Yes, the very faint streaks are caused by stars that moved with respect to the comet during that 1/2 hour period. The individual LRGB exposures were median combined which suppressed the star streaks to an extent, but not totally.

Back when we used film exposures to image comets it was common to see large numbers of bright star streaks on the image. It looked like the comet was racing thru a snow storm. I have several superb prints done by Tony Hallas of comets that he photographed with 4x5 inch film at 1 hour exposures that were guided by hand or with the original ST4 autoguider system.

Roland,
Nice picture of the comet.  Are the light streaks at about a 45 degree angle stars?

Brilliant Andrea and thanks so much for that  “breadcrumb” trail, the option “save data for later use” escaped me, now back on track, Glad you were enjoying your new Mach2! Thanks again, Tom

Tom, I can't check here but it is something I realized while imaging.

First you connect to the NASA site and set the query as illustrated in the manual.
Of course you need to select the right object AND the right observing location (this is the point I missed).
In this regard, the explanatory text in the Horizon application could be more precise.
You also set the time window to cover the days you need.
After running the calculations, you copy/paste in Horizon panel and the Ephemeris values get populated.

From now you have different options in the lower right end part of the application:
you can test the tracking, track the target, or save the data for a later use.
In this way you can prepare everything ahead of time and using it later even without a connection.
I haven't really tried this because I was already there, but I am pretty sure it works.

PS: if you get the message: impossible to track because object is below the horizon, just check your location is not Mars or other funny place :-)

this is something that we can do in advance of the session, because the "tracking plan "can be saved". 
 
So I think we just have two methods also for field use, and it is great!

A remarkable image indeed! Perhaps Roland can use his maths skills to calculate the width of the small outgassing core at the approx. distance of 100ish million miles distance from us. Should be possible to figure out with the known image scale.

Re: ASCOM 6.5 released, upgrade or not?

Luca Marinelli
 

Pierre is right. I updated the ZWO ASCOM driver when I loaded software on a new computer in May 2020 but it appears that ZWO, wisely, went back to ASCOM 6.4 a couple of weeks later. I will simply update the ZWO ASCOM driver and roll back to ASCOM 6.4 to ensure compatibility with APPM. Thank you both to Pierre and Ray for the quick responses.
