Re: Not keeping date up to date; + lunar tracking speed error:
If you are using the app, there is a checkbox on the bottom left of one of the panels (might be the Telescope entry panel, or the Advanced panel).? The checkbox is for sending the UTC time from the PC's clock to the Gemini's time counter each time you connect.
There is a button to set UTC immediately also.? ?You might try those options to see if your trouble is corrected.
It's also worth double checking your settings for latitude, longitude, and elevation. Those settings are in Degrees, Minutes, Seconds, even though the delimiter is a dot "." that seems like it should be a decimal?point.? It is instead the European delimiter that is a comma in US usage.??
?If entering time using the handset, this is the instruction from the Gemini1 manual:
Gemini1 time and date UTC format
UTC Date/Time
The "UTC Date/Time" menu item is where you set Gemini's real time clock (RTC).
Upon executing "UTC Date/Time" the UTC date and time display freezes but the RTC continues to keep time.
The display of date and time from left to right reads as follows:? "yymm.dd hh:mm:ss"? ? (yy = year, mm = month, dd = day, hh = hour, mm = minutes, ss = seconds). ________ I get my UTC time here:
So if the UTC showed ?2019, Nov 20, 06:15:25 am? you'd enter in the Gemini
1911.20 06:15:25 Other conditions:
Midnight 12:00 am hour = 00 For time after noon like 2pm = 14:00? enter like
1911.20 14:15:25
Hope this info helps! Michael

Thank You Paul. I'm not a Raspberry pie user, but appreciate your reply. Thanks!
Thank You for the short list, Chip.
Looks like the only thing for me to add is the Gemini ASCOM driver (maybe. It may already be onboard)
All the rest I have and have been using. Except the ASCOM controller.
I would imagine the ASCOM handset (virtual) will just need getting use to for me. But shouldn't be any problem.
This shift to a Losmandy Mount may be much smoother than I imagined.

Re: Not keeping date up to date; + lunar tracking speed error:
I used our moon as a test for visual tracking New Years eve ( It allways amazes me with a 12mm eyepiece it looks like you are looking out of Apollo 11's window) it tracked fine, even after 30 min.

Yes,
that¡¯s my guidescope.. I am aware it may not work, but it better because
if I have to go to an off axis guider, I would have to also replace my filter
wheel and filters too.. None of them are the ¡°thin¡± variety and I
cannot reach focus in the Raptor..
The
goal is to mount my ADM Laser Finder.. My camera chips are small and sometimes
an object lands outside the FOV, so I just reach up and switch on the laser and
I can see which way I need to move.. I also *really* want the two scopes to be
on the same object so I can easily swap cameras, so I don¡¯t want a
clamshell..
??? But
it may not work at all.. First I have to make it guide at all.. On my Dec axis,
the PHD Guiding assistant shows a LARGE time lag when I switch directions AND
all the data points it shows on that window are double points.. I am aware of
all the different ways to deal with the Dec.. Guide in one direction only.. Don¡¯t
guide in Dec at all, etc.. Just got to try it and address the issues as they
appear.. I am not very hopeful it¡¯ll work, and certainly not the way I
want it to, as I am not doing wide field with a large chip..
??? We
shall see..

I avoid rings like
the plague for anything but a finder scope because they are so prone to flexure
and movement through the night that for me they really make for poor guiding.

more of a clamshell type of mount for your guidescope? Prime luce has something
like that I used on my tak sky90 and it holds everything really nicely

Maybe,
though I don¡¯t think the Losmandy adapter will fit there so I think it
has to go in a different set of holes.. If you look at the guidescope rings,
the image shows 4 sets of adjustment screws.. It is also drilled to use only
three sets.. So there are seven adjustment holes that are all the same size..
Once the rail is on, I would be attaching the adapter.. The adapter is the same
as the base of the guidescope rings.. i.e. remove the rings and what is left is
the adapter..

will have to use the ¡°side¡± holes.. Let¡¯s see if I can attach

Derek,

Remove
just one screw, noting the tension with a precise instrument ¨C the human
hand.
Then
take it to a DIY or Ace store as suggested by one of our other friends. When
you get back to the mount insert that one screw in the ring and tension it as
much as you had before.
?
Since
the other two screws in that ring (not to mention the three in the other ring)
weren¡¯t changed the boresight (to use the proper artillery term) of the
guidescope won¡¯t have changed significantly.
?
The
difference in boresight alignment (main vs. guidescope) will be trivial, unless
you are trying to keep things within arc seconds. I know of no reason worry
about that unless you are shooting very long exposures with poor polar
alignment.

how are you setting the date??
Lo all,
I seem to be having a problem with the Gemini 2 on my Titan keeping the date up to date.? The time is remaining correct, but it lags behind on the date, I have had to go in and update the date every time I go to use it during December.? I know you might be
thinking "battery" but it has been replaced as of the first incident, and is showing 3.10 volts in the web interface.? Once I update and set the date the targeting works good, so it seems to just be Gemini is not keeping up on the date.? I have tried both
turning the mount fully off as well as leaving it on in the observatory, seems to make no difference.
Also just this last session I began to have a tracking error when going to the Moon, the mount would got to fine then take off @ about 8X "tracking" the Moon.? Yea zip!!!? there went the Moon!? In manually switching the tracking with the HC to SideReal it goes
back to tracking at the SideReal rate without an issue...? Kind of weird, I'd think if the tracking was going to be messed up it would be messed up at any of the different rates not just lunar.? I think I will try a factory reset next outing and see if anything
changes, but any thoughts in the mean time??!
Thanks & CS!

Re: Not keeping date up to date; + lunar tracking speed error:
This is more of an FYI since it doesn't directly?relate to the gemini time settings, but I have started using Dimension 4 time sync on my computer that continuously updates the time every 30 minutes or so (user configurable) to ensure the clock on the PC is as accurate as possible. it syncs across multiple time servers and runs in the background. oh and it's free :) When i then sync the mount to the PC time, i know it's accurate
?
?
Brian, I will check this out tonight when I get home and see if my Gemini still has the correct time. My tracking the New Years eve was as good as my polar alignment. I left the mount to sit for 30 min. And it was just a little off where I left it. I am
too new at this to really help though. Clear Skies?

Re: G11 survival kit - Oldham Coupler
Derek,
Here in the USA the Oldham couplers are sold by McMaster-Carr.
Also, try ZORO.COM for an extensive list.
If you want to see a full list of options, visit RULAND.COM They are the maker.

I really don't think freeing up the gearbox fixed anything, but in my case it eliminated an obvious *potential* issue from the matrix.It is weird that those gearboxes bind like that.
The belleville washer holds the precise amount of side load on the bearing, thereby making the worm rotation more predictable for the PEC. Do it!
If you have a PEMPro graph, you are a step away from loading a PEC curve to the mount. Follow the PEMPro instructions and add it! It is literally like 3 clicks. You can add a 2 worm cycle correction and theoretically bring down that 7.5x error from the gearbox.

Derek where do you want to add a rail - on top of the guidescope rings?
Besides,
why do you care about the thread if you are unwilling to remove one?
***
Because
I want to put more bolts into the existing ¡°extra holes¡± to add a
Vixen rail.. But yes, I will try your suggestion and remove one from the middle
ring.. If my focuser and extension tubes are tight, it should stay put.. Nice
idea, Thanks!

Derek,

Remove
just one screw, noting the tension with a precise instrument ¨C the human
hand.
Then
take it to a DIY or Ace store as suggested by one of our other friends. When
you get back to the mount insert that one screw in the ring and tension it as
much as you had before.
?
Since
the other two screws in that ring (not to mention the three in the other ring)
weren¡¯t changed the boresight (to use the proper artillery term) of the
guidescope won¡¯t have changed significantly.
?
The
difference in boresight alignment (main vs. guidescope) will be trivial, unless
you are trying to keep things within arc seconds. I know of no reason worry
about that unless you are shooting very long exposures with poor polar
alignment.
