Switching gear2

Funny how during the CCD Jurassic period, exposures that lasted several minutes (vs several seconds) were considered to be they easily eclipsed the image depth of photographic film taken with much longer exposure times.

Now we are not-infrequently seeing images that have 20-50 hours worth of data. Rather than buck the trend, I've decided to embrace it with a new
SBIG guider that works in front of the CFW and LRGB + 3nm NB AstroDon 50mm filter set (pictured).

Not sure what 50 hours at 3nm will show...(given the current weather very little ) ....but time to switch it up a bit
