High Resolution Tracking Gemini 2 Level 6...

Dnorton All Messages By This Member #83007 Edited At the risk of sounding like an idiot, I hate to ask a question that may have already been asked... I recently bought the G11 with Gemini 2 at Level 6. I promptly updated the firmware with the firmware update program. ? In the HC menu is a high-resolution tracking mode for RA and Dec. I have tried to find out specifically what that means. I cannot find it. Maybe I am stuck on the word "tracking". Is it high resolution for slewing from object to object or is it high resolution tracking for guiding during astrophotography? I've been out under the stars with the mount exactly twice and I did two nights of photographing the Cocoon Nebula. A total of 10 hours. First night I had it turned off. Second night I had it turned on. I couldn't tell a difference. Using the ASIair Plus, my guiding error was .25". If anyone can explain this high-resolution tracking to me, I would appreciate it.? ?

Hi Doug, ? Sorry, I'm not sure what "high resolution tracking mode" you're talking about? The HC has the RA/DEC 4x resolution encoder settings. These should be turned on. Or are you talking about something else? ? Whether or not that will help you depends on how good your tracking and guiding is, image scale, seeing, etc. It increases the resolution of the servo motor encoders from 0.5626 arcsec/tick to 0.1407 arcsec/tick. Since L6 was primarily designed and tested to work with this new 4x encoder setting, you should have these turned on for best results.
Dnorton All Messages By This Member #83009 I have seen the check boxes for the RA and DEC 4x mode. By default each time they were unchecked. I had to check them to activate them. I assumed this was called high resolution mode. I don't have the hand controller in front of me at the moment.? ? Doug

Partridge Member Profile All Messages By This Member #83010 开云体育 The difference is that the software can now detect the position of the motors with 4x the resolution that it could with the old firmware (assuming that the servos IC’s firmware has been updated).?? There are now effectively 1024 ticks per revolution rather than 256.? Should result in smoother, more accurate tracking. ? This has been measured by several end users when the software was first released and the indications were that it did improve tracking (which is what we had hoped would be the case). ? ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of Dnorton Sent: 12 September 2024 15:39 To: [email protected] Subject: [Losmandy_users_io] High Resolution Tracking Gemini 2 Level 6... ?

Yes, have the 4x encoder settings turned on with L6. There's no reason not to, and a few good reasons why it might help.
Dnorton All Messages By This Member #83012 Thank you for the information, that really helps. Now I know to keep those settings on. I will check every time I turn the mount on. And yes, my mount is the new L6 and the chips have the updates. Thanks again! ? Doug
Chip Louie All Messages By This Member #83013 If you didn't buy the mount and Gemini 2 new from Losmandy you should verify the firmware versions. Go into the HC - Hand Controller - sub menu then select the "Info" screen and you will see the HC firmware version, Mainboard firmware version and the PIC chip firmware version. As I recall the current versions are: Mainboard L6.02, HC 1.61 and PIC version 3.? ? -- Chip Louie Chief Daydreamer Imagination Hardware? Astrospheric Forecast - South Pasadena, CA?

Doug ? There are no stupid questions here. I do sometimes have a stupid answer... ? Hey, I'm an ASIAIR user and if you are seeing 0.25" guiding error you are doing as good as it gets. Your mount and PA must be very good and the seeing excellent to get those numbers consistently.? ? -- Chip Louie Chief Daydreamer Imagination Hardware? Astrospheric Forecast - South Pasadena, CA?
