I'm sure you are testing the new flattener on the oldie but goodie. Can't wait to see your results!

Hello Astronuts,

I have been imaging on and off for the last week or so in temperatures close to 0F. Tonight it is slated to drop down further to -12F (-25C). It's already at -18C, so this should be a great test to see what dies first - mount, laptop, or camera. Right now the Mach2 mount is happily slewing at 1800x with no muss, no muss.
The QSI 683 camera fan is sounding a bit strange, like it's being strangled. In the past the filter wheel froze up because the rubber O-ring shrunk and the motor shaft wasn't making contact any more.
The 10" Mak is waiting for photons to arrive, 'twill be interesting. Let cha all know how it went later tonight.

Wes,

I will be interested in your asi air + findings but I know you have to wait a bit longer.
I still think you’ll want a HC but that’s my opinion, just comes in handy for the quick nights without the fuss of setting a micro computer, laptop or rsb pi.

I might have an extra one or two HCs, if so I can give you one. Can’t wait until you get your AP1100 because you’re going love it. If not box it up and I’ll buy it from you full price. Can’t collect AP scopes but I can collect AP mounts.

Re: ASCOM 6.6 is out. Anybody tried it yet?

Terry Martin
 

Yes, everything looks fine.  Like I said, I don't know if copying the file over is the right thing to do, but everything looks ok and everything is working.


Re: ASCOM 6.6 is out. Anybody tried it yet?

Emilio J. Robau, P.E.
 

Can you get into APCC?  How does it affect the performance?  My installation was purely accidental.   Time to roll back.


Re: ASCOM 6.6 is out. Anybody tried it yet?

Terry Martin
 

I did a search for the JPLEPH file and found it in a few locations.  I copied it and pasted in the ASCOM\Astrometry directory.  Now APCC opens and I can initialize the mount.  Not sure if that's the right thing to do, but things are working.


Re: ASCOM 6.6 is out. Anybody tried it yet?

Terry Martin
 

No, it's not just Alex.  Same thing has happened to me.


Re: #ASI_AIR_PLUS What should my expectations be with AP? #asi_air_plus

Thanks Roland, a perfect answer from the man himself !  I look forwards to my name coming up on the list! I emailed Daleen yesterday but I guess I have a while to wait.  


Re: ASCOM 6.6 is out. Anybody tried it yet?

Emilio J. Robau, P.E.
 

Oh No Emilio.......   I am not rebooting my computer.   Maybe Ray will opine.  I don't have an error yet, and I think I did reboot after I installed.  I actually installed 6.6 in hopes of getting my environment settings to work.   However, it had nothing to do with ASCOM or APCC.  I am hoping, no offence, that this is limited to your individual set of hardware and software applications. 


Re: ASCOM 6.6 is out. Anybody tried it yet?

Alex
 

I installed ASCOM 6.6 and everything seemed to work fine with it.  However, I had to reboot the computer today, and when I start APCC, I get this error:




Note that I also have APCC 1.9.3.3 installed.

The mount controller (CP4) retains whatever it was sent from any source. It retains that setting in its memory until you send another instruction to turn that function off.
PE On/Off setting is retained forever until you modify it via an outside source.
Same with the PE curve and lots of other settings and data (slew rates, button rates, tracking rates, guide rates, encoder settings, etc.)

So if you turn on periodic error correction using ascom, does it turn off as soon as you deactivate Ascom?

I realize the mount will be limited in function but the convenience of asi air especially setting up at a darksite makes it well worth the loss of certain capabilities. If I had a remote observatory on the other hand I would likely completely switch over to a PC, But that is not what I am trying to accomplish here

Re: #ASI_AIR_PLUS What should my expectations be with AP? #asi_air_plus

I have the HC (actually one for each mount - 1200,1100,Mach2)

With the Mach2 which I use mostly for imaging with a computer and APCC (and TheSky) I have no need for the HC and have not used it much.

When doing visual, I use the HC. A lot. (I’d rather not use sky safari - I’ve tried it out but the HC imo is more convenient. )

Also, if I’m doing simple DSLR photography, I don’t bother with computers and just use the HC.

Prior to APCC I would use the HC while imaging… for things like nudging the FOV and goto etc. But now I pretty much do all that in software.

Correct im using asi air but I am asking if a pc can activate features like PEC before I use asi air

Zwo made an ios/android ap interface that hosts indi drivers for most mounts and zwo proprietary cameras, focusers, filterwheels. This runs on asi air. Because it does not use ascom you have limited functionality with an AP mount.


Re: #ASI_AIR_PLUS What should my expectations be with AP? #asi_air_plus

 

>> Since I have a PC I wonder if I could just change them and then go to asi air and not have to worry about it

The "PC Driver" is the ascom driver. when you use ASIAir, there is a completely separate Indi driver, so it won't pick up those values 

I have the ASIAir Pro and various other computers. IMO the ASIAir is a great starter kit, but i would feel very limited using it as my imaging control device for my AP mount.

Re: APPM & ASTAP - HELP #APCC

Joseph Beyer
 

Everything worked flawlessly with the APPM run and imaging last night with my Mach1 / Tak FSQ-106 / ASI6200.  The APPM mapping run took 19 minutes for a 48 point Dec arc model.  The missing Dec and RA values may have been from not having the mount connected to NINA the previous night.  I also reinstalled the H17 star database into the ASTAP folder into the programs directory before starting.  Here are the settings I used, hope it helps someone.

I just finished setting up a new NUC for imaging and am having a similar problem with ASTAP and an ASI6200.  I was using the same software setup on a laptop which was working excellent for APPM.  I set the same parameters on the new computer and it's not solving.  I never had to bin the camera but changed the down sampling to 2.  One thing that immediately sticks out is there are no Dec or RA values in the image FITS header from the new setup.  I was trying to solve the saved images taken last night before trying to start an APPM run. They wouldn't solve in ASTAP as there are no DEC or RA values in the header.  Below are the values from the laptop which was working fine last I used it and the NUC which isn't.  I haven't used the laptop since I've uploaded the newer version of APCC-Pro.  I'm currently using v1.9.3.3 on both computers.  If I don't have any success tonight with the NUC I'll try the laptop again and see if that still works.

Laptop - working computer:
ASTAP Version: 80.9.577, 64 bit, date v2021-9-9
Star database: g17 *NOTE*: the website now says this database is obsolete and has been replaced by H17.  The older G version should be deleted

APPM Parameters:
Camera settings: Binning 1; Subframe - full frame; Auto Dark Subtract - unchecked 
Plate Solve Settings are DEFAULT except for pixel scale for the Tak FSQ-106/ASI6200 and down sampling of 2

NUC - will not solve
ASTAP version: v2022-1-23
Star database: H18 - this is a more extensive database than on the laptop

APPM Parameters:
Originally I set all parameters to match the laptop but solves failed - the program timed out at 30 seconds.  In my experience images solve in 2-3 seconds.  Tried changing binning to to 2 - no solves.

I'll update tonight.

Re: Ap-1600 Re-Greasing Experience

Emilio J. Robau, P.E.
 

Thanks Roland,

I am giddy with excitement.   I think this is the first time I figured out how to invert and transfer the curve to the mount by disconnecting and reconnecting in Pempro.   I think I am going to tweak the polar alignment to get even less drift.  The mount is in an observatory and has held alignment pretty well over the years.   Dale Gent just gave me instructions on how to do the coordinated dithering in NINA utilizing the direct guide functionality.  I can't wait for a clear night.   When I saw a flat line PE after loading the inverted curve, my wife could hear me downstairs yelping with glee at 1 am on a work night.  With the sensitive CMOS cameras most of us own now, three minutes is a long time.   Fifteen minutes is an eternity.


Re: Ap-1600 Re-Greasing Experience

Roland Christen
 

You may find drift to be sufficiently low if you are within 2 hours of the zenith. If you are east, west or south of that you may start to see both RA and Dec drift. Then you may want to use the APPM model to compensate for the drift. 3 minutes with model is certainly doable for your mount. I'm betting you could go even longer to 15 minutes.

Roland

Thanks Brian,

I do have a model built with APPM and pointing is superb.  Even with an clear across the meridian flip it only takes one adjustment by ASTAP and NINA to get me spot on.  My master scope on the array images at 2000mm with an OAG.  My two slaves image at about 750 mm and 489 mm.   I am thinking that if I have even better polar alignment, I could just about eliminate drift and could go longer in the 2000mm subs.  I think three minutes is acceptable at this time even with my current polar alignment, since the drift will probably not show.  Certainly on the lower fl scopes on the same mount array.   If I tweak the polar alighment, I maybe able to go even longer.  I guess what I am saying is that the polar alignment is now controlling my sub length due to drift.  Is this correct?

Finally, how do you dither?.
