Re: Renishaw encoders

I have a 1100GTO that originally had a CP3 controller that was upgraded to a CP4.  I later installed the Renshaw encoders.  You stated:  "The ring error is mapped, stored in the CP controller and becomes part of the mount's control loop system".  Since my encoders were not factory installed by AP, this mapping has never been performed and stored in my CP4.  How much accuracy is lost by not having this mapping?

Re: [ap-ug] [ap-gto] First try at GIF of comet rotation

Hello Robert and All,

 

>Is there a reason I'm getting permanent failure messages from the group? I get two per message and can't determine if my posts are making it on the board.

 

Robert, your messages are coming through.  The reason you (and possibly others) are receiving “permanent failure” messages is because the original message was sent to both of our user groups – ap-ug and ap-gto – and you responded.  You are a member of one of those groups, but not the other.  Consequently, you’re getting fail messages from the second group.  Sorry about that, everyone.  Please just delete them.  Thanks,

Karen C

Excellent ! The expansion of the spiraling jet is obvious.
Could you remind me the camera and exposure time used ?

Excellent.  So 6.4SP1 is the one we like?

Is there something in 6.5 that you need?
So, where do we stand on ASCOM 6.5?

My new imaging computer will arrive next week. I don't see an option on the ASCOM page to download ASCOM 6.4.

Re: A query about AP mounts / APCC & Indi #APCC

Dale Ghent
 

Not to mention the complete lack of an INDI client library for Windows. The only one that exists is unfinished and has not been touched for almost a decade. There there is also the question of how to support INDIlib and INDIGO, two divergent implementations of INDI that have important differences.

Ray - any comments?
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?
My original plan was to leverage a cross-platform framework based on Alpaca. I even volunteered to create this framework, but the ASCOM team rejected the idea. Thus, the scope of the project has increased as I must develop an alternative.

So, unfortunately, it's become a more substantial project which has had a lower priority than supporting the ASCOM/Windows platform. I can't give you a time estimate because there are things out of my control that could affect completion.

Re: [ap-ug] Comet Neowise coma detail

Roland Christen
 

Thanks everyone for your comments.

I'm trying to make a GIF, which is not so easy because of the changing light from dusk at the beginning to the final images as the comet dropped down into the muck. It will probably be only a limited number of images (maybe 6 total) but it shows the rotation very clearly. Knowing the time we could probably figure out the time for one rotation.

Dean I can't thank you enough for your help also.  You gave me some great suggestions and very much appreciated.  I was like a kid in the candy store watching APPM work a couple of nights ago!  I'm going to try running some DEC models like you have been doing based on Rolando's hand controller update that's coming out down the road.  Could you remind me of your DEC and RA spacing you have been using based on the target your imaging?  All the best, Scott

My 17" spaceship didn't have enough dylithium crystals to penetrate further past the wavy nitrogen, oxygen and carbon dioxide cloud surrounding our earthy platform in space in order to reach out for a closer view. Perhaps the Hubble could have helped?

Hi,

I just uploaded my last image on Astrobin which shows the coma and jets in detail. The comet was definitely rotating during my 2 hour session. I have a number of frames from beginning to end that shows the jets expanding and the streamers moving behind the comet, however I have not figured out how to present a moving image with these frames. So this image is a still picture about 1/3 of the way thru the session. Luminance is a stack of 8 x 30 seconds with RGB colors added of 10x 30 sec for each filter.

The image is noisy due to the short integration of the exposure and the amount of processing (digital development in MaximDL) required to bring out the very subtle jets as they rotate around the nucleus.
