Encoders, yes or no?

Jim Bachesta All Messages By This Member #83639 I use my? upgraded 2010 Losmandy G11G for imaging. The wish list would be to improve guiding using absolute encoders.? If my understanding is correct, the E port on the Gemini-2 is not designed to support that.? ? With that said, I would pay the dollars to add absolute encoders and placing this on the Gemini-2 road map would be fantastic. ?
Chip Louie All Messages By This Member #68143 Hi David, Serge told me the magnetic rings are the same. The difference is on the pickup side of the encoders which are programed to count differently which yields you a 10K tic encoder system. I have not tried them as I wanted the highest working resolution so I stuck with standard 310K tics for the Nexus DSC which is amazing in use.? -- Chip Louie Chief Daydreamer Imagination Hardware? ? ?Astropheric Weather Forecast - South Pasadena, CA?
Sonny Edmonds #68122 I like Scott's personal advice to me at the time of my Purchase: "Don't tinker with it, just use it." As it is, my Losmandy mount works perfectly. https://www.cloudynights.com/uploads/gallery/album_8062/gallery_252608_8062_305774.jpeg -- SonnyE (I suggest viewed in full screen)
Dave_Kentsbeer All Messages By This Member #68119 Hi all, thank you for the great responses, there is a lot to learn with Astro gear and I have a long way to go, I don't intend to use push to so dont think I need the shaft encoders, if I'm honest I didn't realise the motors had encoders, I assumed they were an upgrade but googling last night realised that the goto system needs them to work. Thanks again.?

I have a GM8 with a Gemini 1 which I had kept for the ability to use with shaft encoders. The problem is the Gemini 1 only supports 10K tic encoders and modern encoders as sold by Astro Devices for the Losmandy mounts are 310K tic encoders so they do not work with Gemini but work great with the WiFi enabled NEXUS DSC with a smartphone or tablet. I love to use the GM8 in PUSH-TO mode with the mount balanced and the clutches free for one finger movement. It works very well as the Gemini still moves the RA just fine once I find an object. This is the best way to use a Losmandy mount IMO? ? -- Chip Louie Chief Daydreamer Imagination Hardware?

René – is that any reason the axis encoder support couldn’t be ported across to the Gemini-2 – my guess is it should be trivial to do this – possibly even with support for higher resolution eoncoders? Support for high resolution axis encoders would be a great new feature! :) When done well, these could eliminate the need for PEC and, sometimes guiding. Regards, ? ? -Paul

David C. Partridge Member Profile All Messages By This Member #68110 开云体育 If you are using a Gemini controller, you have the motor encoders. ? So the question is what’s the point of axis encoders – it buys you the ability to use the mount in “push to” mode while keeping the Gemini-1 informed of where the mount is pointing. ? Also if there’s any slip in the system the axis encoders act to correct for that. ? Sadly the Gemini-2 doesn’t have code to support axis encoders which is a real shame. ? René – is that any reason the axis encoder support couldn’t be ported across to the Gemini-2 – my guess is it should be trivial to do this – possibly even with support for higher resolution eoncoders? ?

All, Sorry for the barrage of newby questions, I am working my way through the manual to get to grips with all the features on the G11, my first motorised eq, tonight's topic of interest is Encoders. If I understand there are 2 types of Encoders, the type that is incorporated into the motor, this type uses pins on the motor din plugs to connect, and the other type that fits to the RA and DEC shafts and connects to Gemini via the encoder RJ45 socket..Please correct my if I am wrong! I understand what they do so my questions are: Except for manual guiding when attached to a computer running Stellarium were the benefit is obvious,? are they useful for any other purpose and worth the money? What is the best type, motor or shaft? Thank you in advance..

Bill Gardner All Messages By This Member #68107 I’ve had my GM8 since the 90s. At the time there was no Gemini goto unit for the Losmandy mount except for a third party after market mod. The encoders that attached to the RA/Dec gave push to capability to the mount when connected to a computer or a unit such as the JMImini max. With the introduction of the Gemini, the mount needed better resolution and that came with the new upgraded motors instead of the old stepper motors.?
