Automating Meridian Flips with APCC Pro and with Sequence Generator #APCC

Dean Jacobsen
 

I am researching setting up automated meridian flips with Sequence Generator.

I have set up a one hour [15 degree] meridian delay in in APCC for point mapping and then for imaging past the meridian.

What I am wondering is whether the information concerning my APCC defined meridian delay is accessible to SGP and is is used by SGP in calculating the modified meridian position?

I can't find any information on this in the documentation.

Woops. I'll correct that.

Very sharp detail—a nice rendition of this object.
BTW it is in Hydra, not Centaurus.

Hi Ron

The grease kit is not listed on the A-P web site, but if you call them and ask for one the person who answers the phone will know exactly what you need. I believe that the kit also comes with instructions, and if you need advice to help get you started they will usually put you in contact with George.

Re: APCC, APPM pointing model and camera rotation

Roland Christen
 


I suppose your answer is the same regarding the camera does not come into the equation.
That is correct. The camera does not do anything as far as mount functions. It's like an eyepiece with a crosshair. You can rotate the crosshair all you want, it has no effect on the mount tracking rates.

Thank you Rolando,
 
I should have phrased the question better. I’m most concerned with unguided exposures rather than pointing. Just wanted to make sure that unguided exposures won’t be affected by camera rotation.

Hello,
 
I’m about to purchase the APCC Pro software from Astro-Physics for my AP1100 mount. I do a have a quick question regarding the pointing model.
 
Will the model be affected by the rotation of the camera or removing it for maintenance and mounting it again in the same orientation?
What is the impact on pointing, tracking, etc..?
Do I have to recreate the model after such event?
 
Thank you very much.

I bought APCC pro and planned on a pointing model. But once I put the Mach1 to use I found I did not need a pointing model. I've not found any pointing error.  If there is some because I unclutched and moved the mount a plate solve syncs it in 2 seconds. (ASTAP)
I have read that it would help if I just track without guiding for longer exposures. Since PHD2 is free why "not guide". 
I've found no need for a pointing model to improve accuracy. 
I'm a newbie - this May was my3 year. I like to enjoy the hobby so I opt for fun and fast results.
This often means that I also skip all calibration frames.

Ron,

 

As Dean said, please just give us a call at 815.282.1513 during the day.  The Grease Kits are not available to purchase on our website because we only sell them to people who own AP mounts, such as yourself.  Cost is $35 and includes worm grease, spur gear grease, a brush, and comprehensive instructions.

 

If a daytime call doesn’t fit your schedule please email me directly at karen at astro-physics dot com and I’ll be happy to help you.

Transporting counterweight shaft and weights

Barry Megdal
 

I made a case to transport the counterweight shaft of my (now sold) AP1200 out of PVC Schedule 80 pipe fittings – was a nice snug fit and worked perfectly.  Picture is here: https://www.dropbox.com/s/hr5p327p4kocrcc/counterweight%20shaft%20case.jpg?dl=0

 

For the counterweights, I would attach two or three of them to a short piece of aluminum rod of the same diameter as the counterweight shaft, and then put that in one of the small tough bags with handles sold by dive shops for transporting diving weights, such as https://www.akona.com/products/gear-bags/product/~745-WEIGHT-BAG---AKB-#:~:text=The%20rugged%20weight%20bag%20is,drain%20holes%20for%20quick%20drying.&text=Dual%20heavy%20duty%2C%20brass%20YKK,and%20reinforce%20wrap%2Daround%20handles.

Re: Regreasing an Astro-Physics mount

Roland Christen
 

As far as springs, nothing to worry about on your gearbox. Just use the lever to back off the worm, then remove the 3 screws that hold the gearbox to the mount axis. That's it in a nutshell.

Of course once you back off the worm, the RA axis is free to move and can swing wildly if it is unbalanced. Make sure you are in park3 position. I usually pull one of the counterweights down to the farthest position so that more than compensates for the scope weight. That way the RA axis will naturally stay put in Park3 even when the worm is backed off or the gearbox is fully removed.

Hi Rolando,
Thanks for that. I'd love to see a quick video of a Mach1 gearbox being removed from the mount if possible. (I have latest version - one of the last Mach1 batch).
Regards,
Paul

Wish I could see that one from Michigan. My nearest cousin.

Objet : [ap-gto] M83 - Southern Pinwheel in Centaurus
 
I recently uploaded this image which I took during a period of clear skies (but bad seeing) on the island of Hawaii this past March. I was testing out new pointing/tracking software with the keypad and used my 1600 encoder mount with the 175 EDF refractor and my trusty QSI683 camera. I have a few more images of other galaxies which I plan to post.


This spiral was really nice visually in the 175 refractor, and also in Chris Erickson's 130GT refractor which he generously loaned to me. We had a star party several days later to which we invited a number of locals and one professional astronomer (from Keck observatory) who was kept busy by the guests explaining stuff they saw in the eyepieces. That day we also had a wonderful house blessing, Hawaiian style, which included the observatory, where the Kapuna sprinkled the observatory, scope and mount (oops).

Hawaii Island can have incredibly good seeing and exceptionally clear dark skies, but depending on the trade winds can also have very poor seeing at times. When we came at the end of February, we learned that the major observatories on Mauna Kea had just had a horrible winter with most times no clear skies available. It was their worst winter season in memory. Fortunately by early March we a had a clear spell, but of course the Moon came to spoil it for deep sky imaging. Nevertheless, it is really cool to be able to swim and snorkel during the day and see Orion cresting overhead, in short sleeve weather at night.
