M81, M82 and IFN
« on: Jun 27, 2017, 20:40:07 »
Seeing today's APOD (https://apod.nasa.gov/apod/ap170627.html) has reminded me that I haven't posted one of the images I took in France.

It's the usual Sony A7S on the Tak Epsilon. 4 hours of data in 30sec subs at ISO 10000.

I'm pretty pleased that in the lower left of the image, the brown dust colour is definitely beginning to show.  You won't find that in the average LRGB image of the same area.

Lovely image Mark, lots of dust showing.  You certainly seem to have found ways around the problems with that camera.

I have to say though I am sure I have seen this image before, or was it a previous attempt at this area?
Hopefully Doug will pick this up in time for tomorrow's meeting.

Hi Mark and Carole

A great pic Mark!  Doug is away and I'm doing the presentation this evening (supplied by Doug).  As this month's PoTM has been selected and this could be a candidate I'll leave it to Doug to make a choice for the July Society Meeting.

Best

Hugh

Amazing Mark, well done on the competition! Incredible depth and even rendering of the IFN across the field of view.

BTW reminded me I have 150x300s of this area to process! That's 300s not 30s ;(
