Hello all: While I had my G11G off the pier yesterday I was searching for potential causes for the runaway Dec motor that was mentioned a week or so ago. Someone else had a similar issue as well. Upon

Hi Bruce, I make these power booster units as a service to our Losmandy owners group. I don't have them mass produced, nor buy them and mark them up. I don't maintain a sales website. It is just a

Hi Bruce yes I also am purchasing This power supply from Michael as this sounds like such an elegant solution to the balancing problem. I have used the balance function on my Gemini2 controller many

Hi Russ, Sounds like a good technique.? Can you list the brand and model number of the power supply you are using?? Does Michael Herman sell them?? Does he have a web site? Thanks, Bruce

After over a week of scratching my head. Trying this and trying that, I'm back to imaging again. Target tonight is M53. I would go for a galaxy, but I'm one globular cluster short of getting my RASC

Scott, In addition to all the excellent info supplied in other replies, here are some other resources: Chris Woodhouse has a very good book on Astrophotography and how to use PixInsight with example

Very nice reports, Jamie! Especially the good news that you are getting things working as you expected. It's like a car...when it's working you enjoy the ride. When the check engine light comes

I recently had my Gemini-1 repaired by Michael Herman. The main problem was my Pyramid fixed 13.8-volt, 5-amp continuous power supply was suspect. So I purchased Michael's 17-volt power supply, having

Is this with 0 TVC? ------------------------ Jim W Phoenix, AZ. USA

BTW here's an example last night regarding auto backlash compensation adjusting over time you can see the overall DEC RMS doesn't change much, but the dec guide pulses (the vertical lines) go from

So a couple of things. * So far it seems that east biasing fixed the issue. So since I was not having issues before, maybe the worm has come loose with spring? My current adjustment is also pretty

Looking at my old run, I can see a 30min separation between the spikes, so the East bias may not have fixed it. It might just be luck that it did not show up before I turned in. This does not show

Here's the logs. So I found when the scope was pointed south to the equitorial line, where I did my calibration, there was no spikes. The spikes only showed up about a half hour after tracking, so

Hi! Yes, please post the log. And: in which direction was the scope aimed when you did not have any spikes? And when they returned, where was it aimed? Magnus Den 2021-04-08 kl. 16:44, skrev Jamie

So, yes the spikes do happen, and look the same when guiding is disabled. The part that confuses me is why I have never seen these before. My setup has become very routine. I can't imagine my balance

It's exactly the same as what I see.? My imbalance was caused by the focuser plus DSLR and the SSAG.? When I turned the OTA in its rings to the other side the same thing happened just with the

Hi! A few details on these spikes: Looking at Jamie's guidelog, it seems that for each spike in RA, there is a small pulse in RA in the /opposite/ direction of the spike. I can not get my head around

Dear Jamie, Because there is a possible interaction between PHD2 and the Gemini doing the RA motor drive, I think you must eliminate the chance that PHD2 is generating the spikes. I think you just use
