I have now have a ROR for my G 11 G on Its tripod And I am having problems with restarting Gemini 2 back on
My problem is when I restart I am not getting a good initial goto
so my question is - what is the best way to shut down and restart?
so far my technique has been move to the park position which is RA and dec horizontal and then I shut off electricity. But when I return I do a warm start never seems to be pointing at the correct target?
What is the correct workflow ?
Should I leave the mount turned on All of the time instead??
Any other suggestions?
what are you guys doing?

I do a cold start with CWD every time and do a modeling. Pier mounted too...

Hi Ron
If you warm start from CWD, try a goto and sync on the first target. that should sync your existing model with real-world

Hi Ron,
Like Jamey just said, when I have some pointing trouble, I do a Park at CWD, then shut off the Gemini power.
Then I set up the CWD position:?? I loosen the RA clutch.? I then use a "torpedo" bubble level, to?put the counterweight bar horizontal, getting that level, moving the RA setting circles to something convenient, then rotating?back 90 degrees to get the counterweight bar vertical again.? ?I then retighten the RA clutch knob.
Then I loosen the DEC clutch knob, and rotate the scope to be horizontal.? Then use the level to get the dovetail level, then use the setting circles again to move that back to CWD position pointing the scope toward Polaris.? Then retighten the DEC axis.
Then I power back on the Gemini using a Cold Boot.? That erases all possibly messed up Model values back to zero.? Then I double check the UTC time and location information.? At that point, my GoTos are normally quite accurate.? I then do a 1 star Alignment.
Note that first Align to Bright Star does not actually change any Model setting from zero value.? That first Alignment only sets the encoder positions to the Gemini...really it is doing a Synch.
You can then Add Align points if you wish. Give that a try.
I would not leave the Gemini powered on all the time, it is not necessary from the way it was designed, using the internal RTC device to keep the time counted, and using the SRAM to keep the location and other information in storage.??
Some other ideas to evaluate:? ?
I have not tried Park at Custom point, which I think is what you are doing to park with the counterweights horizontal.? In theory it should work.??
However, I would do the?Cold Boot with the Gemini not connected to the PC/laptop.? I would check to see if Gemini.net has "set Time/Date on Connect" checked off, and uncheck that.? I suggest you try and see if somehow those in Gemini.net are somehow? over-riding the internal Gemini settings, and messing up your Park/Unpark operation.? These are just some thoughts, but worth a few quick experiments to see if that PC to Gemini interaction might be causing trouble.??
Best of luck, Michael

Hi Brian, Look at the Model settings in Gemini.net, using the Advanced panel Model area.?
You will find they remain all zero value after the first Align to Bright star is done.? Therefore it is a Synch.? Only after the 2nd align star is done do you see the Model parameters move off zero.??
Yes, that is what I observe from my Gemini-1 work.? I don't yet own a G-2.? The company software engineer would know if that code changed ... you would be in the best position to seek that.??
All the best, Michael

>>>Look at the Model settings in Gemini.net, using the Advanced panel Model area. You will find they remain all zero value after the first Align to Bright star is done.
I just did this using the hand controller and Gemini II definitely updates HA and DEC Index errors to non-zero values on first alignment after cold start
So it sounds like Gemini I may work differently than Gemini II

Ok. Good to know.??
If you did a Cold Boot then ...it seems the -1 and -2 must be different in operation from a cold boot.??
That means the G-2 believes the CWD position was dead on, whereas the G-1 does not trust that.? The G-1 then uses the first bright star point as the first known accurate point.??
The plot thickens!
If you did a Warm Boot (the default on my G-1 is Warm Boot) then it would make sense that the first Bright Star align would be added to the per-existing model as a new point.??
Have fun!

Michael -
To the point about Cold Boot (which I assume means no pre existing model) - does it matter whether the CWD position is dead on or not? In theory, assuming that the mount is accurately polar aligned, it is irrelevant. All you need to do is point it to a known location in the sky (or know where the scope is currently pointing) and everything should be calculable, basically a single star alignment. Thinking about this non mathematically; if I had a map of the Earth and knew my current latitude and longitude, I can get to any other place. I don't need to travel to a second location to figure it out. It would be similar on the Celestial Sphere. All I need is to polar align and know where I am pointing now, and every other point should fall in place. I can say that my standard imaging practice is not even to bother leveling RA and DEC for CWD; I simply cold start, slew to my target, do a blind sync, and the next slew is within a couple hundred pixels of where I should be. In practice, mechanical slop and inaccuracy in how well the first point is centered would give you a better accuracy with multiple star alignments which I think is the purpose of building a model. And once a model is built, sync would allow you to correct for if you accidentally bumped the axes etc.

Hi Arun,!
In the Gemini-1, a Cold Boot erases the entire set of Model parameters.? Gemini.net shows all zeroes on the Advanced panel.??
The Genini-1 assumed the mount is polar aligned.? Then you do a First Bright Star alignment.? The mount will rotate to that position.? You then rotate the position to get that star in the scope field.??
Then press Enter and it says Aligned!??
But if you look at the Model parameters in Gemini.net, they are still all zero if started from the cold boot.
I think they should be zero, too. If you had been earlier parked off from CWD, say the counterweight bar had been horizontal.? You'd have to rotate the RA by near 90 degrees.? The model should still be all zeros.? Only the Encoder positions should not be zero, they should tell Gemini the initial pointing synch position.
Brian has tested the Gemini-2 and says that the first Bright Star align results in nonzero model parameters.? The question is....why is there a difference in operation between these two generation systems?? I'm saying that if Brian did a Warm Boot, not a Cold Boot as I am, then I think the Gemini "knows" it's last model values and they are preserved (not necessarily zero).? Then Gemini would try to calculate new Model values as he observes.
The point of all this is to help our original questioner: why are his GoTos far off when he did a Park at Custom (that is, wherever he wanted the mount to be parked).? He chose horizontal maybe to fit his observatory space.? That is already an allowed supported Park position in Gemini.? It should be working perfectly when he boots up Warm Boot, and unparks.? If he has done a Cold Boot then his system will assume it is at CWD...where is is not!
All the best, Michael

Wow guys thanks so much for your attention
?so again i¡¯m using a Gemini 2 my goal is to keep the model And go directly to the target In Easiest Manner with as less start up procedures possible
?I was hoping to turn on from the parked horizontal position, do a go to from the park position , align, and go to Target In other words all beginning initially? from the park position - impossible?
Want to easily get back to re-imaging the same object the night before and since I moved to park would presume all I Gotta do is turn on and go back to the target
?
?so you¡¯re telling me I have two options:
?
?1).? park @ CWD, Turn off Gemini,?? then move the scope manually to the horizontal position so I can close the roof Then to Awaken I would Firstmanually move to CWD and then turn on Gemini , warm restart,? go to and sink on first target
2 ). hand control command move the scope the Home position (which is horizontal )turn her off close the roof.? Then to awaken first? manually position to CWD then power up Gemini Warm restart go to sync
All of this seems so tedious - the model is there !?
I suppose even after parking Yet leaving power on then unpark I still have to do a CWD warm restart and then go to align?
What about the sleep mode?
?I can¡¯t just turn her on and go directly to the target rather than beginning always at CWD?

Hi Ron,
Of your options, #1 will surely work...but not what you want ideally.
Your #2 option is wrong...here's how you should be doing that:?
Do start at CWD from Cold Bout and align, build your model etc.?
When you go to Park the mount:
Do: slew to the horizontal.??
Do not?: turn off Gemini after you slew to the horizontal position.??
You must tell Gemini: Park.? Then select:? Park at Current Position.?? Then...turn off the power.
When you reboot Gemini, use Warm Boot and skip any alignment. It already should remember it's alignment from the Warm Boot information.
Try that....it should?work for you!
Also if you have Gemini.net on your PC there is a drop down selection for Park at Current Position.? ?That is a nice way to do it!
Let us know!!!
Best, Michael

Hi Ron
Yes, unless (or until?) you move to more sophisticated DSO type software (think sequence generator pro, NINA, etc.) plate solve probably won't help you with your gotos
Are you tearing down and setting up every night, or do you have a fixed setup you just start up each night?

Ah yes Now Im Starting to understand the utility of SGP and NINA which I have not seriously imaged with as ?SharpCap is so easy, hard to stop Yes, my setup is fixed ? So are you saying that from my horizontal Home Position, ?I could power on Gemini2, then using SGP can do a direct goto by plate solve? ? Ron

Hi Ron
For DSO targets like you showed (and wow, that is a demanding focal length) it would be easier than that:
- cold start from CWD each night - press "start sequence" from SGP - go to bed :)
i simplified that a bit, but basically that's what I do each night.
You just start and end each night from CWD position (SGP will park it in CWD position when it's done imaging)
you cold start because you do not need to build a model, plate solving handles everything for you
When I first heard about this, it sounded like magic, but it turns out it works, and it IS kinda magical :) there are many others here who work similarly with SGP, NINA, and other similar packages

Hi Michael
This is exactly the flow I thought that I needed to take
thanks so much for confirming:
Power up gemini.net first then
power up Gemini2 in horizontal parked position , Unpark , goto, align (or synch ?)? on hand control, then repeat addition same obj goto align ( or synch ? ) on Gemini.net
but unfortunately this is the reason I posted the question because Its not yet worked out for me
but now I know that its gotta be operator error? ... working on it
Thanks again
Ron

Hi Ron.??
I think you have the concepts.??
Another useful thing is: you can work on testing this in the daytime.??
Keep your scope and finder scopes optics fronts covered up so the sunlight won't overheat anything and you won't by accident get blinded.? Then just do your GoTos pointing at the sun, as if you were doing solar imaging.
Then you can practice Park and Unpark to your heart's content, while you are not operating in the dark!
Once you confirm you can Park at horizontal, and successfully unpark and repoint at the sun, you should be?good to go for nighttime operation.? ?
I think you can set your preferred Park at Custom orientation, set that as horizontal, and using Gemini.net you can always just park there.? (I just have never tried this myself.)
Very best, Michael
