Hi Martin, that is brilliant.
I have to agree it is possible to do something in under 30 seconds. I dont mean to hijack a thread but I also managed to same
http://www.iceinspace.com.au/forum/a...se.php?a=85246 in 34 10 sec exposures. It really opened up some possibilites want to follow up with other objects.
Although ISO levels are needed to be higher and I also have 12" DOB on an EQ platform. Much more apeture so shorter exposure
Tried to capture more last night but my platform played up.
