Gemini Calculates Refraction setting has to do with goto precision and not with tracking. That setting simply tells Gemini to adjust the goto coordinates for the effects of refraction. It does not

Yep, pointless. There have been 1,243 posts made on this forum over the years about this subject (I counted them...) and I believe the consensus agrees with my personal findings - tracking error log

Hi Ray, Your guess might be right that with "Gemini calculates refraction" turned off, there could be a difference between zenith, say, and East or West directions. Comparing E and W at the same angle

Hi Michael, I am not sure it has been solved. However, without tracking rate correction a mount will always appear to be tracking slightly fast when it is tracking at perfect sidereal rate and

Hi Ray, Thanks for that ...I did understand that but.... I somehow missed the statement that the first step: get AZ correct by the drift method, while pointed at Meridian and Equator, must already be

Yes, but as Greg said, this technique is different in that it uses RA drift at the zenith to adjust Altitude polar alignment instead of standard Dec drift in the East or West. There are advantages and

My mount is the G11-G.?? I beleive I can manage my power needs with a 10a supply.? Just to have a little extra.? ? Les, thanks for the link for the Canon switching regulator.?? 30V 10A

Pointless? I would disagree if you wanted the best tracking you could achieve. Three factors play into the alignment: 1: Has the polar-scope been calibrated to the mount? If not the mount is

Thanks to all for your comments on this issue. I believe it is clear that having a precisely level mount does not preclude an accurate polar alignment or accurate GOTO performance. Certainly, as Chip

Magnus IMHO "interrupted" can only come from one of four things: A): A handset Ra/Dec button was activated during slew (either by touch or electronic failure, aka a momentary short cct); or

For a GEM, once the computer is aligned leveling the mount or tripod makes no difference for GOTOs operation. But a mechanically plumb tripod or pier is more stable, settles faster and your elevation

Hi Greg, Thanks for the notes. When using the PHD2 drift tool, it is only the DEC drift you want to null out (not RA drift), as that tool says in its instructions. [ repeat these 2 steps... When you

This subject is a current topic on the Astro-Physics group (#59424) and the subject of using PHD2 was discussed. PHD2 displays both the DEC and RA drift in the Drift Alignment tool. So instead of

Works if your level is the right size to straddle the socket head screw on each side of the DEC axis... mine doesn't. And I find it easier to adjust things if I don't have to hold the level in

Hi Rodney, Good report and nice that you enjoyed the night. Here is some more info in case you want to build more a accurate sky model...at a "permanent" location. By doing a "Synch" only, you left

I think amperage also depends on the load. When I slew a really heavy setup, I see the amps much higher - 2-3Amp Thanks Brian Brian Valente Brianvalentephotography.com Sent: Sunday, November 5, 2017

Why I bought a Losmandy to replace my iOptron. The alignment process works well. But the push-to slip clutches are a mixed blessing. Makes it easy to balance the scope when changing hardware config,

Something I want to note as well as far as building models, etc. During my recent learning curve of this new GOTO system, this being my very first, BTW, I went with our local Astronomy club here in

Does the G-11 have the 492 digital drive or a Gemini? If it’s the 492, I’ve measured the power consumption at 250mA when tracking and 400mA slewing at 16x. Nowhere near 3A. And there’s no reason

Hi Thomas The G11 will be happiest with a voltage somewhere between 15-18v. I use a standard 12v battery and use a 12v upconverter (lots available on amazon, etc.) As for power on the pier for the
