great detail! i'll have to check this out more closely
This is around an area passing close to the zenith here about half way between orion and the southern cross. It's not too far from Canopus. There's a lot of very faint stuff in there. More often than not it's imaged in widefield because there are supernova remnants similar to cygnus. This a close up in a brighter region next to the pencil nebula NGC2736. The only thing you're able to see visually would be the bright star in the center of the field. This about 5.5h of integration in 10min exposure with a QHY9 FSQ106N and a duo band filter.

Re: Pole master on G11 with Digital Drives
You know this is a funny issue. Years ago when I got the PoleMaster there were issues with the drivers. It was related to power saving features of the PC but a workaround I found that worked was to open a video of anything in the background and for some reason the PM software worked fine and did not lock up anymore as long as the video was playing.? I think this was fixed with later drivers but I don't recall which one I don't think it has need changed in a few years now so it should be stable. Worth trying it out, you can do this inside and just see how long the camera keeps working to see if this fixes the issue for you. Worked for me but I have been using SharpCap for long enough I don't remember this problem well.?

I've literally spend many, many nights doing drift alignment due to the fact I can barely see Polaris due to the slope of my observatory roof getting in way.? Luckily with SharpCap, I only need to get close to obtain the initial image before I rotate the G11G, 90 degrees for secondary image.? If this indeed does work great, I will be thrilled!!!!!
Now if I can only fix my ROR issue, I will be set.? Roof seems to be 'twisting' during its opening/closing now.? May have to brace it using 2x4s and X pattern inside roof.

Re: Clean and Lube G11 Gears
Hi gang,
All the comments have been good. You can lube everything but not the clutch friction surfaces.? Those should be kept dry and clean.
The factory recommends a heavy grease asctgeybyse in assembling new mounts, but most owners say this will separate over?time and elevated temperature. The lighter volatile part will creep into the clutch region and capillary action will pull it into those friction surfaces.? So most owners have recommended SuperLube multipurpose grease with Syncolon, a synthetic teflon, that (it's ads say) won't separate.??
For those imaging, see the PDF about a high friction clutch pad type ..very beneficial for imaging work.? But those higher friction clutches won't slip.? So don't try pushing the mount around if you use them ...only use the motors.? You can balance DEC with the clutch loose and the counterweight bar horizontal, but you balance RA by looking at the DC power amps going into the Gemini motors when you sleep in opposite directions.??
(I have a power supply that bousts the output voltage to a safe 17V, boosting torque by 44% over a 12V supply.? Better: this supply shows you the amps being used by Gemini and it's motors, and better still the input is totally polarity protected.? Great for battery use where you might put in the wrong connection.)
When you reassemble:
The key thing is to reduce Periodic Error (PE). All the drive parts can contribute to PE.? They are:
1. The worm.? You show a brass worm, which is the "precision brass worm".? You have one on RA and one on DEC. Only the RA worm matters for PE because that's the clock drive for the RA.? So I recommend you test the PE of each worm (when it is on RA of course) and pick the one that gives you lowest PE for the RA drive.
2. The Oldham Coupler.? (Even the G11 tucked motor drive has an Oldgsm coupler!) This must be exactly lined up, with ideally zero movement of the center white plastic part as the RA worm axis turns.? You also want no angle between the gearbox drive axis and the worm axis.? Any angle there will cause the worm to speed up and slow down, which will look exactly like worm PE. There are other couplers that may have no PE, but there is little space to install a better variety.? I've been trying!
So just do your best to line up the input and output shafts.? For me, I had to use a thin rat-tail file to slot or enlarge the gearbox mounting holes, to wiggle the gearbox position to the best location.??
If you have a tucked motor system, I am unsure how you adjust that Oldham coupler alignment.? The gearbox is not driving the Oldham coupler directly...the gearbox drives an outer transfer gear, and that drives an inner transfer gear on a separate shaft.? That shaft end drives the Oldham coupler that drives the worm.? On the earlier straight out motor and gearbox the gearbox location is very accessible.??
3. The gearbox.? The plastic gearbox over time and wear can misbehave.? There is a clear signature from the 1st to 2nd internal gear that has a 1/7.5 gear ratio.? If there is a problem with that set of gears, you find a 1/7.5 worm period oscillation in RA, and you can detect that in a PE evaluation.? The PEC implementation was only designed (so far) to work on integer fractions of a worm period...but a 1/7.5 repeats every 2 worm cycles....so PEC cannot cover up a bad plastic gearbox problem.? See the attached PDF for ideas on replacing the plastic gearbox with a metal one.? The metal one has only integer gear ratios...so PEC would work if necessary.?? New plastic gearboxes are about $35 from the factory.
See the other attached PDF about ways to improve the mount drive behavior.? One key is to eliminate worm side to side movement, by constraining the worm.? If temperature never changed, the worm blocks alone could be locked in place to hold the worm bearings tight.? But trmperatures do change.? I use a Belleville R4 size spring washer and install one behind every "far" worm bearing (RA and DEC) and I polish down the OD of these work bearings so they can slide along the worm block mounting cylinder, like a piston.? The spring keeps the worm and it's bearings tight against the Oldham coupler end.??
The factory recommends the Okdham coupler be loose, but I allow the spring at the far end to keep the Oldham coupler parts compressed.??
That's about it.? See the attached for thoughts about improvements.
All the best, and everyone stay well and safe.??
P.S. The new virus strain is predicted to spread twice as fast and result in twice the fatalities.? We must increase our caution level over the coming months... don't let your guard down.??

Hi Russ,? No, it doesn't work that way. The reason is mostly having to do with the slight misalignments between the mount's mechanical axis which is what you are aligning with the NCP when using a polar scope or PoleMaster camera and software and the actual optical tube in the mount saddle. This is orthogonal misalignment, you can mechanically correct this but there is no good reason to do so as this correction is a part of what the Gemini controller does when it builds the model during mount alignment. The Gemini alignment model is used to compensate for errors in the optical tube alignment and mount mechanicals. So you do not need to mechanically correct the orthogonal misalignment using shims between the dovetail and scope rings like we used to do back in the day thank heavens!? -- Chip Louie Chief Daydreamer Imagination Hardware?

Hi all
I have a new improved version of the HIP star catalog that i've loaded
into the files section here
- based on HIP2 and is in Gemini (.guc) format. this is 117,000+ stars
- has notes section included (not very interesting but does make note
of star color)
- so far i've been able to load it into my hand controller and use it
successfully
- i fixed the quote problem so now you just enter HIP1234 unstead
if?"HIP1234
loading takes about 30 minutes?to the HC
These are J2000 coordinates so have J2000 checked (which it is by
default)

and the other you can search a given ¨C ie user defined ¨C distance from
