How long does it take your software to dither between frames?
I recently picked up a RASA 11, and I'm still getting familiar with it (I've only had it imaging one night so far). I expected the shorter images, the larger disk space requirements, and the massive stacking-with-drizzle disk requirements. One thing I didn't fully think about was the amount of time it takes to dither. In the recent past, the dithering duration just wasn't very noticeable between 300-600 second exposures. Now, I'm finding that I can capture 30-second images and then spend nearly a minute dithering (sometimes it's as low as 15 seconds, but even that adds 50% to my capture time).
I assume part of this is the DEC backlash I have (CGX mount), but I thought I had that pretty well-tuned. Another contributor is the added weight stress that the RASA puts on my CGX (I'm contemplating sending it in to Celestron, or getting it HyperTuned). I am using the internal guider in KStars 3.4.3.
How about you? How long does your rig take to dither after a frame?
