Do we sell time? No, it's not ours to sell. The installation including the scopes and mounts belong to Carnegie and they allocate time to various groups for research and training. We get time on the scope. We donated the scope, FLI donated the camera with electronic focuser and I believe the filter set (10 filters) was also donated.

That’s very interesting, Roland, and thanks for the additional background.

Do you ever sell time on the Mak to remote imagers?

We have a number of other mount installations around the world with 20" RCs that are doing professional work (not taking pretty pictures). We have learned a lot about what works and what to avoid, and this is our primary purpose. Taking pretty pictures is just the icing on the cake.

It seems to me that the cost of constructing such a large and robust building in that remote and forbidding place, laying the electricals to it, equipping it with the support electronics, and so on, must outweigh the cost of the the current scope it houses by a factor of several. Or 10. If you don’t mind an indelicate and intrusive question: After committing whatever level of funding to the cause, why stop at 12”? Why not go 10% higher and double the aperture, twice the bang for only a little more buck? That place looks like it wants the 24” PlaneWave on an el Capitan that you showed at NEAF!

Re: AP600 vs Mach 1

Roland Christen
 

I have a 10" dia. ATS pier with 1600 mount and 175 refractor in Hawaii. I can focus easily at high power with no noticeable movement of the object. I also image with it in wind gusts and see no degradation of the star shapes.The scope sticks out above the walls of the observatory, and sometimes the wind gust are strong enough to blow loose papers all over the observatory but the scope is not affected. The ATS pier is like a dead column of concrete.

Which is where most vibration comes from with portable instruments in my experience.  Now I believe that a robust rap test (or as in my job the "ping test") is a very severe test.  I've found I can get just about any scope/mount combination to ring if I hit it hard enough.  For example, if I gave the diagonal of my TEC200ED/AP1200 system a good thump with my index finger, while watching the image at high power, the image would indeed  go through about a half second of a well damped vibration.  However, a lower level touch or mpulse would result in no movement of the image.   The system had a high quality "Q", meaning it takes a certain amount of input to get its attention.  So from a practical point of view, for me, the better test is the ease of manual focusing at high power.  That involves me actually touching the focuser, providing a relatively continuous low level series of inputs or impulses to the system.  I've found if a system is easy to focus at high power, it also has rather decent wind tolerance.  I've also found that in general, spring loaded worms can display a bit more of a tendency for vibration when focusing compared with some drives that are not spring loaded (however, those can vibrate as well from a bit too much backlash).

Re: APCC error: FindFreeQacIndex: no free entries!

Ray Gralak
 

Hi Barbara,

This message is usually caused when APCC cannot process commands from the driver and other applications fast enough. This happens fastest when APCC connects to the mount via TCP or UDP because APCC polls faster in that case.

If you are not doing this already, try starting APCC first and do not enable the option to connect itself to the driver. Once APCC has finishing starting, connect ASCOM applications that use the mount.

My experience with storing a reflector vertically, face up, is that the mirror provides a surface for bugs to die on. I store my refractor in Park 4 position (horizontally), partly because that gets it out of the way of my observatory door and it’s bay, and partly so that any water drops will fall on the side of the tube, where they will run off, rather than getting on the optics if I’ve forgotten to cover them.

I did not install the Windows computer - left that up to another person. The system was installed about 9 years ago, but still going strong. The only thing wrong now is a layer of dust on the front corrector of the 12" Mak. It has never been cleaned. The mount has had no maintenance either. If it wasn't for Covid, I would probably have traveled down there for some upgrades to the software and general maintenance.

Skies down there are very good and very transparent. Seeing is sub-arc sec most of the time.

Re: APCC software

 

Hi Luke

in my opinion APCC has tremendous value for any AP mount. It's definitely worth inserting into your software chain, even if you use it sparingly now. 

There are too many features to list, but among the best ones are all-sky modeling/dec-arc modeling for more accurate tracking results, custom meridian tracking limits to increase your imaging time across the meridian, safety features like parking the mount on connection loss, etc.

Brian

Sorry for the silly question, I will soon be taking delivery of a new AP1600 and wish to prepare for its arrival. I am using an AP1200 atm with NINA and the AP ascom platform. This works well for me.

 

Question:  what are the main advantages in using APCC and is it only worthwhile with encoder optioned mounts? Due to the incredibly poor imaging weather this summer, I still have a number of new features in NINA that I wish to learn so don’t want to learn new software atm unless there is a significant gain to be had.
