Title: M17
Post by: GB_10D on 2011 July 21 04:28:01

End of June gifted us with two very transparent nights in a row, so I used the 90 min. of astronomical darkness per night to image this low elevation object.

Gerhard,

Very nice!  And I thought my 200 minutes of total darkness was bad this time of year.  :surprised:

At my lattitude (48N) every km further north means a considerable drop of the length of astronomical darkness. 100km north of my location they have none at all by end of June.

But things are getting better now ...

Actually, there was no guiding at all  ;)
The ASA DDM85 tracks perfectly at least for 20 min with my setup. I didn't bother to test with longer exposures, because mostly I use 5 -10 min.

Best regards,
Gerhard

I'm at 45N.  It's amazing that a change of only 3 degrees latitude this time of year drops the minutes of total darkness in half.  Wow!
