Post Dolly Speed
My new dolly build has two speeds, 7.5 feet per hour and 4.5 feet per hour. I was wondering if the slower speed will work for night sky shots. My system is "dumb" so I have no way to "move shoot move". I have a feeling that 7/8 of an inch a minute might be to fast.

Any suggestions what an appropriate speed would be?

Don't you mean the faster speed will be no good for night stuff? 7.5 an hour seems pretty quick. I have no experience in night work but.

I just worked it out. You mean the 4.5 feet an hour might be too quick? I'll guess yes but there's only one way to find out. That's unless someone that knows what their talking about speaks up :)

Yes that is what I meant.
I would test it but if it's not overcast here it's -30 and I get up for work at 5:30 so I haven't had a chance to get out there since I built it.
I just thought I could get some input, if not I'll test it some time.

you want to keep it to the .1" to .2" range per shot so if you assume 30 second exposures at 300 shots that's like 3 hours per 6 feet or somewhere around 2 feet per hour. ;)

I thought that might be the case, thank you.
