Mike,
Indeed I had forgotten you do this from inside. So - yes it stays on, or should (I've not tested this as its from the planetarium GOTO function). It will lock on the point where the GOTO ends.?

Isn’t ideal for my remote setup to have to go back and forth between the HC and inside to the PC with Sharpcap.

? ? Hi Mike,
So - there is no command to control AutoLOCK. It turns on a closed loop tracking system whereby the ServoCAT and the AN lock around a point (where it is turned on OR where it was 3/4 second after the last HC move to center it) ... and the ServoCAT adjusts its speed to keep the error at zero.?
To use:
-The AUX switch has to be up
-The HC has to be in GUIDE mode (it makes no sense to lock in any speed other than GUIDE since you can't center it using JOG or especially SLEW). Either GUIDE slow or fast.?
-you have to be using it with an Argo Navis running version 3 or later firmware?
The AUX switch enables it (or disables it if flipped down). It does not turn it on. It is the action of turning on SYNC (on the HC) that then turns on AutoLOCK. The RED AUX light will come on. This indicates it is locked. It will lock on this point in space all night long with zero accumulated error. Now you can use the HC (again - in GUIDE speed setting) to move around the field to (re) center the object if visual. The lock will turn off momentarily, the red LED will go off - and stay off as long as you are centering. It will lock on the new position 3/4 second after any button was last touched. I have been doing this with my 12" set up in my living room for 2+ weeks now - finding an object low and to the east - doing a GOTO to it - then turning on SYNC when the GOTO is done. Then what I do since I'm not actually looking at anything is I use the HC to get 0.00 0.00 on the AN screen... it will stay on this for hours until it's near setting in the west....?
So - for imaging. Good question. Now that I'm considering all this stuff. So what you can do is you can just tap one of the buttons on the HC - that will turn off lock and 3/4 second later turn it back off! It will now be turned on. Of course if you needed and wanted to use the HC to center the object using the imager/screen you'd be turning it off and on anyway. But if after a plate solved you were fine but the AutoLOCK light wasn't on - you can turn on SYNC (HC) and you're set to go.?
I'd love to hear how this works out.?
Some things to keep in mind:?
The vast majority of ServoCAT installations are, wooden dobs. So the precision in-built isn't stellar (no pun intended). Also it is an ALT/AZ mount. Finally, you have a finite resolution re the AN alignment. These can contribute to mount errors and an imprecise alignment (guaranteed for the vast vast majority of scopes and alignments - visually usually not an overall issue). AutoLOCK locks on a POINT in space. So combine those things and you have a) issues were the AN's expectations of where an object SHOULD be vs. where it is will add offsets and b) because of field rotation the object, especially if it was offset to the AutoLOCK 'point' (it is an extended object after all) will rotate AROUND that point over time. Keep that in mind - but if you try it please report the results.?
(make sure the HC is in GUIDE slow, as you might have used it to move the scope to the east using slew - I know - I did and told Bill I thought there was a bug - no - this is BY DESIGN!)
Gary Myers
Additional info re AutoLOCK
-it will continue to try to control the speed in order to maintain zero error out to a 2.5° radius if I recall. If the object goes outside of this the system locks at the last speed used. You can see this in action if you align - find/goto an object - turn on AutoLOCK ... confirm all working ok. Then disengage the AZ axis. You will see the error continue to go up and up - and the motor will go faster and faster - once it gets to 2.5 degrees it stops increasing the speed.?
-Local Sync is something I came up with FIRST (YES! I am proud of that) BEFORE it showed up in the LX200 (first commercial system to offer it). It works extremely well. One SHOULD ALWAYS use it as it is unusual, again wooden imperfect mounts/alignments, to find objects. I did. HOWEVER, the scope is an ALT/AZ mount! The field will rotate - and thus the error saved for a local sync will change over time. AutoLOCK will compensate for this at least re 'a point in space'. BUT because it is "LOCAL" (that error, that offset is LOCAL to where you are at the time you set it, it will be wrong in other areas of the sky. In the past one had to remember if leaving a field to turn Local Sync off - and then back on again when finding a new object. In version 7.0C that is done for you automatically! If you go a GOTO more than 10 degrees from where you set it up - it will rest LOCAL SYNC automatically (and 'beep' in the process).??

Re: Imaging, sensor size, secondary size
Gary, ? My 1982 17.5” f/4.58 Coulter mirror set came with a 4.24” rectangular secondary with clipped corners.? When I built my AstroSystems TeleKit, I bought a 3.5” elliptical secondary and it worked well visually.? When I shortened the truss poles to allow use with a focal reducer, I had no issues with light loss due to too small of a secondary.? But at the time, the sensors in my camera were small – 8 1/2mm or so.? I never used my TeleKit with a larger format camera.. ? But several of my customers use MallinCams with up to a 28.3mm diagonal sensor in an Obsession UC18 without issue.? Another uses a 21.8mm sensor camera in a 22” f/3 SST. ? I am not familiar with the diagonal size in these two scopes.? Perhaps they will comment. ? Yours truly, ? Jack ?

I know I asked a similar question back in 2021 but I am trying to better understand auto lock and use of synch. I have read the instructions in the pdf file for the latest firmware but it isn’t clear if auto lock can only be switched on and off for an object using the local synch button on the handpad or if you can use a synch command from planetarium program. When doing EAA using Sharpcap, I often use the “platesolve and recenter” feature to get my object centered before I begin a livestack. I then like to go into Cartes du ciel or astroplanner to and use the synch command ?on the object after it was platesolve and re-centered so I can tell Argo the correct offset. Does using the synch command in a planetarium program also turn on auto lock? And if I use the synch command a second time on the same object does it turn it off?
thanks Mike

Another great tool(s) to check fov, suitability etc…is astronomy.tools website. There are lots of great calculators on there for both visual or imaging. You can also see what a particular object looks like with multiple camera fov’s super imposed. I like it because it is interesting to compare different bin modes vs seeing vs pixel size

Re: Conversion to a Smart Telescope
Paul, If you are looking goto a system that does plate solving and has to ability to do final “goto” using plate solving, then look at the “eFinder” system from . It is DYI. But it works well. We have it on the clubs 40 and works with the ServoCat. There even is an encoder less version.? But if you are imaging, would it not be better just to use what you already have? Bob ?

Re: Imaging with my 15” Obsession
Gary,
Stellarium is talking to the Argo Navis via the ASCOM driver for the ServoCAT via the ServoCAT PC port and provides the remote slewing capability.
After the 2-star alignment you set the Argo Navis to "From Planetarium" mode for the remote-control slewing feature.
I wanted a NUC made for telescopes.? The Eagle has an aluminum chassis with threaded holes to mount on any type of telescope, has 12-volt power distribution, outputs for dew heaters, gps module, SQM etc.
The Eagle connects to my home network and I control it remotely from a laptop inside my house using MS Remote Desktop.

Subject: Re: [ServoCAT] Imaging with my 15” Obsession? Ah Hickson 50... the home of the deepest I've gone visually. The 5th member of Hickson 50 is a visual 18.6 (mag listed often is 19.3 which is blue I believe)... took me 25 minutes at 500x to confirm 3 visual 'hits' on it ... I always had a stringent requirement for what I called a confirmed hit. That was using my 30" in Arizona.?
I'm still researching Jack. I see Touptek has a new camera, the? IMX585 Colorful Camera ATR3CMOS08300KPA
which has an HDR mode that provides extremely low read noise and near 14 stops at a gain of 177. The only down side is the field is relatively small.?

Re: Imaging with my 15” Obsession
Yes that is correct. I use Sharpcap Pro and astroplanner or Sky tools

?Mike, I'll check out that group. So - you're using a NUC whereas Richard is using an Eagle 4S. And for you Mike - you 'connect' to the home wifi I assume? And thus using a PC inside and remote desktop you then can run the NUC, correct??

Richard,?
Fantastic images... gobsmacking. And this is wireless to inside the house using the home wifi??
May I ask: why the Eagle and not say a Mele Quieter 4C? Of course you'd lose the SQM (which I agree is nice - but in my LP not necessary as it might be more depressing than helpful). Which program communicates through the PC port of the ServoCAT??
