DMK sensitivity

Wow.... I am trying out some moonlit Ha imaging tonight with the DSI Pro II - guiding through the DMK - I think the DMK might be more sensitive - I'm sure it brings up more of the Tarantula with a 1 sec exposure than the DSI does! Might try some DSOs with it!

Be interesting to see a comparison, Lee.

Some at 1 sec, 5 sec, 10 sec, 20 sec and 30 sec.

Ahhh, go the full hog, try 120 sec as well

I'll have to get around to it - haven't installed the capture software yet - I have only used it with PHD guiding so far.....

oh, ok

I'll wait. I've got nothing to do for the next 40 minutes

You will have to make sure that You have your tonal range matching, remember the DMK is only 8 bit while the DSI is 16bit.

When did you get the DMK? Which one?

They're great cameras!

I picked up a DMK 21AF04.AS at Bintel a few weeks ago - mainly I wanted a no hassle sensitive guide camera, with the option of maybe doing some planetary/lunar imaging at some stage. I don't regret it....
