For reference, at 1500 frames per second you could hand hold the scope and get stable images :-) -- Edward

FYI the Gemini Telescope.net driver user manual is available via the app itself, under the Help! menu [image: image.png]

From the driver manual: Normally if Gemini tracks into a safety limit the mount stops and must be manually backed away from the limit before you can GoTo your next target. Whilst this is a minor

Just curious what this option/command does?

Jim, At 100 frames per second this should not be an issue. I've used a Skywatcher 150mm visually on a Losmandy G11 with classic drivetrain and it had no issues with vibration. Granted this is a 150mm

Firecapture autoguider works just fine with Gemini-1. You must of course have a working serial cable, ASCOM, and Gemini.net applet working. PHD2 does not care of any orientation of the autoguide

I have a G11 with Gemini 1. Does anyone have any experience using Firecapture to autoguide on planets? Is this possible? Anything else needed?

adequate. that was my thought. i'm probably a little more positive because it IS such short exposures it should be fine -- Brian Brian Valente portfolio brianvalentephotography.com

Hi Chuck image camera with 3.8 micron pixel size? Would that effect or contribute a significant error? It depends (isn't that like most answers in astronomy) ;) If you have a specific example you're

Brian Your reply about image scale got me thinking. What if you have a guide lodestar with 8.2 micron pixel size and an image camera with 3.8 micron pixel size? Would that effect or contribute a

Completely agree. In the end its all about images and frankly I am pretty happy with the test images I took the other day. I'm about to embark on collecting a lot of data on a single object and I'd

Apologies. I think we were posting at the same time! I saw your response after I hit send

It's not a dumb question at all. I was just trying to offer some perspective here on how much you want to be fiddling with things (which we are all inclined to do) vs. how much better are your images

Very unlikely.? A 5' scope will act as a sail in the wind. ------------------------ Jim W Phoenix, AZ. USA Losmandy GM811G, NINA 1.11, ASI2600MC Pro, Sky-Watcher Scopes

The reason I ask is what I see in PHD Log viewer is, which says 0.76", so in my mind I now take 0.76/2.2as/px = 0.38pixels on the imaging camera, which is great I do see 0.5"/sec RA drift and 0.12"

yes, do just be clear i'm talking about the components of the guiding, not the total guiding rms If you have a perfect mount with 0 error, you are still limited by other conditions (seeing, wind,

Yeah I think I get what you are saying (not sure how you can tell the "wasn't guided out" error -- where does that come from ? If I have a 1" guide error then that will also be a 1" error In the
