Subject: [ap-ug] Yet Another M31: knocking the rust off in bortle 8

After a summer of little time for astrophotography and my main imaging rig undergoing a near total reconfiguration to accommodate a QHY600, I finally was able to get a few sessions in over the month of October and break in the new system. I haven't seriously imaged broadband before because I live under lusciously gray bortle 8 skies in the jet stream-inflicted mid-Atlantic, and escaping this atmospheric morass means a few hours' drive in any of the cardinal directions... so I've just kind of stuck to narrowband. I'm actually pretty happy with the outcome of this little project, my first Ha+LRGB. I've since fixed some spacing and tilt and am working on some more targets as weather allows.

Re: Guide rate always being set to 1.

Guide rates for AP mounts should always be set at 1x sidereal.

Subject: [ap-gto] Guide rate always being set to 1.

Hi,
I have the CP4 and have set the guide rate to 0.5x. It is set this way in each Ascom driver as well.  I am using APCC standard.
I understand that I should use a guide rate of 0.5x.  However, every time I start up PHD 2, it sets it to 1x.  I have changed all the settings I can find in PHD to 0.5x but it still changes it.
Any suggestions?
Thanks, Tom


Re: best power schema for nomad set up

Andrea Lucchetti
 

Following the suggestion,
I am going to use the battery to power my MAch2.

I assume that 13.8v or even 14.2 when charged 100% is perfectly fine given that it can be run also at 24V.

can someone please confirm this?
Thank you
Andrea

Very nice rendering Dale. Amazing image given the sky conditions! Wonderful to see the imagers employing capable methods and equipped to overcome dismal lighting challenges.

Re: APCC Pro v1.8.8.3

Ray, I just updated to this version of pro.  I seemed to have lost my pointing model and horizon limits.  Is there a way to get them back or do they get erased with the update? Dui


Re: Guide rate always being set to 1.

Tom Blahovici
 

I know I saw this recommended quite a bit.  However, I guess I will just use the 1.0x guiding.
Thanks, to all.
Tom


Re: Guide rate always being set to 1.

Dean Jacobsen
 

I have been using the 1.0x guide rate on my AP mounts for almost 20 years with several guiding programs and most recently PHD2.  Never had a problem/

Stainless Steel Insert for Counterweight Shaft Threads

M Hambrick
 

After watching Tony & Moose's most excellent video showing him unpacking his brand new Mach 2. I would like to know if the stainless steel insert in the counterweight shaft holder has been incorporated into the other mounts ? In particular the 1100 ? 


Re: Guide rate always being set to 1.

 

1.0x is the best guidespeed for AP mounts

not sure where 0.5x recommendation came from

Re: Guide rate always being set to 1.

Woody Schlom
 

Tom,

 

In the past Roland has almost always recommended using the fastest guide rate you can set.  He said all the slower rates are for manual guiding, but computers react much faster than humans and work better at the fastest guide rate.

yes that's correct. As you know, this additional option is as simple as turning on a checkbox.

For anyone who might be interested, the declination-arc tracking method uses a different model than the standard hemisphere models that APCC Pro has been using. It has been in testing for almost a year and a half and will be available in the next major point release of APCC Pro.

Re: Results of our AP1600ae unguided imaging

Dean Jacobsen
 

Declination arc tracking built into APCC?  I’m interested.  Now I will be able to use that instead of the three and four line maps I have been using with the standard hemisphere models.

I wanted to share our latest results from using the our AP1600 with absolute encoders, doing unguided with
APCC/APPM model

This is from last night's run, we used 900second (15 minute) unguided exposures of NGC 1097 on CDK17, image

Overall I'm pretty happy with these results. We were admonished to use guiding from the start, but we had faith in
the AP hardware and the APCC software.

We rely on APCC and the APPM model builder. The model was approximately 180 points on each side, limiting it
to 35 degrees altitude.

Ray has done some great software improvements based on our results over the past year. We are at a very
demanding focal length for unguided @ 2930mm. He has been very responsive and helpful, as have all AP staff

We still have work to do in other parts, and we would like our keeper rate to be higher, but progress, not
