Quote:What kind of exposure time are you using to find stars without too much adjustment
Quote:1) What kind of exposure time are you using to find stars without too much adjustment. Assuming a sensitive guider like this QHY or a Lodestar? I am in a rich part of the milky way currently and 1s seemed to do the job, but there are less stars than expected.
Quote:2) I am using my .63R/C with this setup and kind of expected the off-axis stars to be better shaped. But in general they have the funky distortions OAG tend to present. Is this the norm?
Quote:3) Any setting tips for using a OAG with PHD? I am using it with my c925 so the scale is pretty small. The bumps on the tracking graph pretty much take up the entire graph. But my stars in the image itself are nice a round.
