Don't know yest. Most probably a full frame 35mm CMOS at some point.

We have excellent transparency at our observatory and the sky is really dark. The seeing (star scintillation) is not always good, but the Honders is a medium focal length scope (1160mm) so it is ideal for semi-wide field objects. I intend to go extremely deep with it and will be using the fast optics to gather detail in very faint structures.

AP1100AE PHD2 guiding with wind

ap@CaptivePhotons.com
 

Been a lot of PHD2 discussion recently, so what's one more... 

Dry season is starting soon here with more clear skies, but it usually comes with some wind.

I realize the real fix for wind is a wind break, but some of us just have to be out in it... 

So far I am getting really good guiding, 0.20-0.30 if the wind is calm and the seeing good.  I've hit 0.18" at times for goodly periods.  Really good, and not very sensitive either, I have tried short exposures, long exposures, with a model, without a model. I am sure I could screw it up, but all the reasonable stuff just works.

But the season change brings me to the question: Is there anything you would recommend changing to respond to light wind, the kind that moves the OTA around a bit, say 3-8mph with a C11 and dew shield on it.  In particular do shorter exposures help, or do they fight the encoders?  Longer?  Bigger min moves? 

I do realize the encoders only "see" movement within the mount's mechanism, not shifts that also involve the tripod, etc.  And some of that movement is brief impulse that bounces back, and some may be an actual shift that guiding has to take out.  It's not a simple issue. 

That's why I am wondering if experience has any guidance for the best approach in calm vs windy?

My first inclination is do nothing, but there are folks out there who have probably seen and fought every problem so... advice?

Linwood

PS. And yes, when Is see a girl with a dog on a bicycle blowing past, I will bring the mount inside.

What if you got 4 "Honders" owners to image the same target night after night with the same cameras and filters?  That would be easier than running 4 Honders in an array on the same mount.  Then make the data publicly available for anyone to process.  (Free!)  Such a concept.  ;-P

Funny enough, every Thanksgiving and Christmas here in Hawaii, before COVID, my wife and I would host a "Thanksgiving in the Land of Misfit Toys" for all of the elderly, widowed, single or just lonely astro-nuts here on the island. Just being an astro-nut was enough to qualify. I believe Marj & Roland attended at least once.

It will be nice to re-commence with social gatherings at some point. When that finally happens and if any of you happen to be on the Big Island during either of those two holidays, let me know and I'll assign you something to bring to the festivities!

At one point I thought it would be fun to come up with an acronym for the gatherings but upon reflection, TITLOMT didn't create the vibe I was looking for.

It's actually a very good mount from the standpoint of accuracy. Dual encoders and other goodies. I will be running it fully modeled and unguided.

Nope, the 1600 production mounts are painted white so you don't bump your noggin on it at night. This mount is cobbled together from rejected parts that had scratches or nicks, etc. Basically a prototype suitable for testing stuff.

Beautiful mount! Are all the new 1600s coming with polished aluminum instead of paint? I'm on the list - hence my question.

Thanks!

Re: Followup: Re: [ap-gto] Mr. Whang's Mach2 with TOA150

Hi Roland,

Thank you for the explanation.  When you told me the springy feeling is not a problem in your email, I believed so but didn't know why.  Now I understand the reasons behind it.  My other mount (non-AP) indeed had large Dec backlash and also the static friction that you described. These bothered me a lot.  These problems do not exist on Mach2 and I am very happy with it.  Even if the price for this is slightly less rigidness against strong wind, I can happy accept this tradeoff (no matter one views it a tradeoff or not).

Cheers,
Wei-Hao

Re: Unexpected mount movement

Ray Gralak
 

Hi Alex,

It remained shifted for the half dozen or sub subs until the meridian flip. After the flip and platesolve, the
correct centering happened.
I think this supports the slipped clutch theory. The offset stayed until the plate solve after the pier flip accounted for the offset position.

Re: Need help connecting APCC to Mach1

"Reinstalling APCC is not likely going to help unless APCC had become corrupted through some disk error on your computer. More likely is that the settings file has become corrupted. 

So, try deleting:

C:\ProgramData\Astro-Physics\APCC\settings.apcc

You'll need to reconfigure the connection."

I'll give it try this afternoon.  

"Could be a cable or connector problem too.
 
Or a popped USB port."

Initially I thought these might be possibilities too but during troubleshooting have rotated connections/cables/ports and it's the same regardless of the configuration.
