Hi George, see this thread about modding with Baader filter v full spectrum mod of DLSR
http://www.iceinspace.com.au/forum/s...d.php?t=122289
Two issues you may want to bear in mind
1. You may want a newer DLSR for better ISO and lower noise, a 1100d is a good choice.
2. Being in Darwin, you may want to look at a cooled DLSR to minimise noise (which adds considerable cost to the mod).
Cheers
Bo
