Thanks Bill and Mikotoy!

I hope to make a movie of that transit (when I have enough time.)

Uh, just for clarification; is your RV-6 remotely operated on the lunar surface?

Thanks Paul, Darryl, Glenn, Chris and Jim!

And Old Frankland regarding

Uh, just for clarification; is your RV-6 remotely operated on the lunar surface?


That would be something! :)

On the unlikely off-chance that you might be inquiring about the rotation angle, I'll explain the 2 reasons I have for it looking that way:

1. The original Criterion focuser does not have retention screws to lock a camera in place (which after further contemplating this awhile back I figured was a good thing for afocal anyway because the torquing of that heavy camera/adapter/EP/barlow load most likely wouldn't be good for the focuser stability over time, also I don't have to worry about slight rotational slipping as its at gravitational rest relative to the focuser (i.e. it won't move while shooting.)

2. I try to resist rotating the image to a "normal" position in software as the software I usually use, Corel Pro X4, claimed on its specs that it had "lossless" image rotation, but that seems to not be available in the actual software package I received (other software I've used through the years has also not been lossless) so I often choose not to do the image-degrading step of rotating individual images (but I sometimes will do it for animations since things are going to get messed up in the GIF anyway, and sometimes if it's going to be on display in my gallery and I think it'll be hard for the un-initiated to figure out what they're looking at :) )

Thanks again to all, and regards, Jason H.
