Got it!  f/15 longboard.  Too funny.

Since it was a long focal ratio board, around F15, I used multi-toenail guiding using the "dig in hard hang on tight" algorithm.

Well done Roland!

 

So what was your guide-rate set at for this particular adventure?  And were you auto-guiding or manually guiding?  I’d say that with such an old longboard, manual guiding would be more in keeping.

 

Thanks for posting this.

Re: Possible to install the RAPAS + RAPM2 on the left side of the #Mach2GTO RA axis ? #Mach2GTO

Roland Christen
 


That would be good news, though I think I would prefer it on the left side anyway. Just to make sure I'm being clear my assumption is using the RAPAS with the mount in Park 3 (scope pointing toward the pole).
I point my scope at Park2 and have no problem accessing the eyepiece with my right eye.

Sebastien, you don't need to put the Mach2 in any particular park configuration to start it up.  So it is OK if you just push the scope off to the left side a little to get your head down to the RAPAS and make the adjustments.  You can then start up the mount without having to return the scope to Park 3.  Because of the encoders the Mach2 knows where it is at startup and doesn't need to be started at any particular position.

Thanks for the info Tony.

Then I wonder if many other Mach2 users could have the same need which would make it worth the effort for AP to drill and tap similar holes on the left side and make such an adapter in a Mach2 version 2 maybe ?

The left side of the Mach2 mount does not have any tapped holes to receive the RAPM2. The Mach2 mount comes with the proper tapped holes only on the right side (as viewed from the rear) and shown in my video. BUT, if it did have tapped holes on the left an adapter would need to be made for the left side as the RAPM2 only works on the right.

Hello everyone,

I was watching Tony's (aka Harley Davidson) latest and much useful videos about his new Mach2 (lucky guy, mine is scheduled for delivery in January) and one of them (ref. https://www.youtube.com/watch?v=d-Ltoqabn8k) made me wonder if it was possible to install the RAPAS+RAPM2 on the left side of the RA axis with the same adapter or say a left-sided version of the RAPM2.

I would find it more practical and comfortable to use my right eye when polar aligning (me being right-handed as well). I therfore wouldn't have to rotate the scope 90 degrees prior to PA, saving a few seconds / minutes more while I setup (I'm mobile most of the time).

Anyway, I think it would be a nice additional feature to be able to choose which side suits you best if it isn't already possible...

CS!

All PW Corrected Dall-Kirkhams come with a manual Hedrick focuser, but PC control of the focuser, including temperature compensation is about an added $1000US.  You can add that at a later date.

AG Optical DKs come with an Optec TCF-3Si.  I have a 14.5" AGOS.

Because of the fixed primary and spherical secondary, Corrected Dall-Kirkhams are relatively easy to collimate and hold collimation well.

The following is only pertinent if you have similar situation at your location.

I have a friend with a PW 12.5, which is a closed tube OTA. He gets great images from it.  However, he lives below a mesa top in western Colorado.  He gets katabatic winds (drainage flow from the cold mesa top downslope) that significantly impacts his seeing much of the time.  Also some vibration impacts unless the OTA happens to be pointed directly into or directly away from the wind.  The bigger PW OTAs are all open truss as are the AG Optical Dall-Kirkhams and many RCs.

Hello Roland,
 
This is a custom made dewshield I think. Made of Polyoxymethylene (POM) Delrin, Kocetal, Celcon etc...
I would like to make my own. We don't have frost here but lot of humidity, f.e. last night 98%.

3D View error #APCC

davidcfinch9
 

Everything is working very well with my new Mach2GTO and APCC Pro except for the 3D View feature.
When I click on the 3D View button I get a pop-up that states, "Load Library failed with error 1114. A dynamic link library (DLL) initiation routine failed." When I click the OK box, APCC shuts down.
How can I fix this?

Re: New Solvers for APPM?

W Hilmo
 

With the current discussion of ASTAP, I wanted to circle back on a problem that I described a couple of months ago, but had not yet investigated.  I’ve had some time to troubleshoot and I understand what’s going on now.

 

The issue that I had was that, when using ASTAP as the solver through SGP, APPM would occasionally get into state where a single solve failure would cause all subsequent solves to fail.  It turns out that what was happening is that SGP was instantiating ASTAP with PlateSolve2 compatibility and a search area of “Max Regions”.  What happened then was that a solve failure would essentially try to do an all-sky solve, with a search radius of 90 degrees.  The subsequent APPM solve failures were occurring because APPM had timed out the original solve and was submitting new solve requests while the first one was still searching with that large search radius.

 

The solution to the problem was to reduce the number of search regions in SGP.  In my case, I was able to change from “Max Regions” in SGP to 2500, which is the highest number below “max”.  I have a fairly small field of view at 23’ x 17’.  Using a search area 2500x my field resulted in a search radius of between 7 and 8 degrees.  A failed solve with this search radius fails in a few seconds.  With ASTAP failing before the APPM timeout, all is well.  Sure, it doesn’t address that initial failure (which in my case looked to be happening because of a really poor star field), but APPM now recovers properly and I can get a good model.

 

I’m hoping that Ray’s implementation uses the ASTAP native command line, instead of PlateSolve2 compatibility.  If that is the case, then it will be possible to specify a search radius directly and this won’t be a problem with sane parameters.  It would be even cooler if we could configure ASTAP for both normal and blind solves.  A “normal” search could have a small search radius, say under 10 degrees.  A “blind” solve could have a search radius of 90 or 180 degrees (with an appropriate timeout).

 

Thanks,

-Wade

Bruce, another suggestion would be the Astro-Tech/TPO/GSO 14" RC OTA. I have the 16" version. It has excellent optics and the truss design is very stable and strong. The focuser that comes with it is only good for visual use so you would need to get a better one for imaging. I have the Feather Touch focuser which works great.
Yes, it isn't a Planewave and I can't speak to its advantages, but I'm very happy with my setup and I get great images. 
Cheers,
Gary
