DSLR 2nd light with Patrick Moore's 15" reflector

There are still some tracking/balance issues to sort out. It seems
that the drive is binding and then slipping, then binding/slipping
etc.

However, I did manage a few short tracked shots tonight to get this...

A nicely burned out core which can be put back in with a bit of
processing TLC.

That's very nice Peter. You picked up some really nice detail in
the nebulousity.

Pete,

Very nice work. Now if you can squeeze in a few extra images of
slightly longer duration to saturate the dim nebulosity, you will have
a killer image.

Nice work either way!

Anthony.

As others have said, it's very nicely done. I suspect this instrument
has a fine mirror. I would love to see what can be done on Saturn with
or Jupiter with a webcam.

It's now had a collimation tweak courtesy of some fine UK planetary
imagers. Apparently the primary could do with some forced air flow
cooling as well (it's in an enclosed box at the moment). Expect some
trial show soon!

I think there's a bind/slip action going on with the drive. Once
that's been identified and sorted, it'll be a killer scope I'm sure.
Patrick seems thrilled with the images which is really nice to see.
