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

That should be adequate for such short exposures. Not great, but adequate. Joe Bergeron Fellow, International Association of Astronomical Artists Author, The Endurian Universe novels Author and

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

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

I own a G11 and am considering putting together a 6” f/10 doublet for imaging the sun. Very high frame rate (>100 FPS) lucky imaging. I would put this on a very stout pier. Has anyone done anything

this. Don't get focused on the ratios and pixel sizes. The point is your error is in arseconds. Your "wasn't guided out" error on your main PE is 1/4" your image scale is 2.2" per pixel. that means

Ah I think I see. Because my ratio of guide to image is about 3:1 then any error in the guider will be 1/3 in the imager so the 15” PE is more like 5 and the 0.7 RMS is approx 0.7/3 This makes total
