Re: Capacity check on AP 1100

mjb87@...
 

I am using a side-by-side arrangement on my AP 1100: a 130mm GTX and a 300mm CFF Cassegrain. With all attachments and the AP-supplied dovetail bars, saddles, etc., I estimate total weight at about 100-105 lbs.

The mount works fine. I'm still doing 3m unguided imaging with pinpoint stars.  (I don't really need to go more than 3 minutes with my ZWO camera.)

I do notice more "shake" when touching the focuser and looking through the 300mm f/15 Cassegrain. This doesn't surprise me and is probably a function of the side-by-side arrangement.

However, my experiment is coming to an end. As soon as my Mach2 arrives (couple of weeks?) and my ExploraDome arrives (two weeks?) I'll break down the setup and each telescope will have its own mount.


Re: New Solvers for APPM?

Hi Bill,

Just curious if there has been any traction in getting new solvers added to APPM?
ASTAP will be added as a plate solver in the upcoming APCC v1.9 release.

I currently use a C11" EdgeHD with an 80mm Stellarvue APO triplet piggybacked onto it in my observatory.  The C11 sits on an AP1100 mount which is on an adjustable Pier Tech steel pier sitting on a cement pier which runs several feet underground up to the observatory.  So, the C11 is essentially 10 feet above the observatory floor.  However, I have grown weary of constant mirror shifting and flopping issues.  While I intend to keep it and fix the problem, I want to explore possible scope upgrades from the C11" EdgeHD despite it being very popular and producing great images.  My skies are Bortle 6 with average seeing.  I'd appreciate any suggestions, not going above $10k.

 In my humble opinion, my 1100 is just adequate for the AP 10" by itself.  I would probably only be satisfied with a 1600 under it.  But I am weird that way. ;-)

No problem, though this configuration is only for viewing, not imaging. 
This mount never ceases to amaze me with its capabilities and smooth performance.
This is not a permanent configuration in my observatory, but one that I mount occasionally.
I like the different width of field, visual views provided by each scope on a target. Adds context to the views, so to speak.
The two larger scopes are mounted on a dual saddle bar. Each of the smaller scopes is mounted on a bar on top of the bigger scope.

PntON on Keypad and APCC

Hi AP,
For use without guiding my current model on the Mach2 brings a small drift without consequence on the poses of 3 to 4 'but which for sessions of 4 to 5 hours of exposures causes a gap between the first and last which makes the trails appear. difficult to deal with on the end result.
It is therefore an opportunity to test the Point + track mode option of the keypad.
My keypad is already plugged in when I turn on the mount and in EXT mode. I only want to have confirmation that APCC open, pointing and tracking correction disabled on it, I can do the initial keypad operations with my sky mapping software and enable tracking correction from the keypad by PntON.

Re: Another Recommendation of the Ridgid Tool Cart for transporting the AP900/1100

M Hambrick
 

Hi John

Yes, the RA assembly just barely fit, and I forgot to mention that I had to cut back some of the reinforcing ribs in the lid of the box to allow the lid to close. I used a 1-inch layer of foam in the bottom of the box, and that made the mount base stick up just a little bit too much to close the lid.

I am still working on the Dec axis cart. I have been thinking about either putting the counterweight shaft in there, or (more likely) putting my cables, CP4, and Keypad.

Re: Another Recommendation of the Ridgid Tool Cart for transporting the AP900/1100

Well done on the Ridgid cases especially the foam cutting done for the RA assembly. Thinking is wouldn't fit
I didn't try the RA assembly into the 22" Tool Box, looks like it just makes it.

Will you store anything else besides the Dec. assembly in the Rolling Cart? Note, and I didn't realize this until later,
that the tool holder at the rear of the Cart is removeable.

Re: Meridian management

Joel Short
 

With SGP you don't have to worry about "minutes past meridian to flip"  SGP will never stop an exposure for something and will wait until the exposure is finished to issue a flip.  So in SGP just set your "Minutes past meridian to flip" to 0.  Let's say your exposures are 10min.  If the mount crosses the meridian at minute 2, the mount will track past the meridian for the remaining 8mins and after the exposure is complete SGP will issue the meridian flip.  Works perfectly and I've never done anything else.  
joel


Re: Meridian management

Marcelo Figueroa
 

What I do and it works perfectly well is to turn off the meridian limits in ACPP and let SGP take over. I usually use about 10 or 15 minutes past the meridian and ensure that the wait for meridian option is activated.
 


Re: Meridian management

KHursh
 

Thanks Andrea,

I am doing something slightly different, I think. I am trying to predict when the flip might occur so I can tell my imaging software what to do. APCC is set to flip at the meridian limits set in APCC, but that time will differ according to the DEC of the object I am imaging. You (I think) have already decided on a 45 minute delay, which is what I may ultimately do, but if my object is at a lowish declination I may not have to flip at all. I can play with my setup during the day and watch what it does at various declinations and write down when it approaches my limits (I should have done this when I set up my limits), but I am trying to ask if there is another way to predict the behavior


Re: Meridian management

Andrea Lucchetti
 

Hi Kevin, there is a similar thread from me about 1-2 weeks ago. I don’t comment here because I still have to practice what I have learnt. 
But if you are imaging with sgp I assume your problem is just to avoid loosing time at th meridian. If your frames are 600s, I think that a delay of 600s is enough to finish a frame and flip.
