This is my quest for the 110 Messier objects. These were taken during 2014 - 15 over a period of about 15 months. I got serious about trying in the Spring of 2015 and so the record go.
I did not realize I needed to post these in this forum and began this in the Deep Space forum inadvertently. Please see the first 10 Messier's documented in, viewtopic.php?f=66&t=5630&p=47434#p47434.
I will continue the Quest with number 11 starting in the next post.

taken 2/20/15 11 x 20s ISO 3200
Note, the planetary nebula, NGC 2438, in the field of view. It is 3000 light years away and was first discovered in 1786. The nebula is not considered part of M46 since it does not share the cluster's radial velocity. https://en.wikipedia.org/wiki/NGC_2438
M69 M69 avg_filtered by John Pombrio, on Flickr
taken 8/7/15 in less than 5 minutes as it was diving below the roof line. This is an integration of 3 x 45s subs
M70 M70.adaptive bin.filtered_filtered by John Pombrio, on Flickr
This photo was beginning to experience some extinction in the lower left corner presumably as the cluster sunk below the roof line. I included a plate-solve for this one too for that reason. With a Declination of -32 degrees, there is significant color extinction as well, which makes the color balance interesting. Taken 8/7/15, integration of 5 x 45s
