Never ever discuss the weather before going out to image. High clouds caused grief during the imaging session, especially at the start.
Although, I think it was Roland Christen of Astro-Physics that first brought it up.

The top image is a sum of twenty-one 5 minute exposures with an Astro-Physics 130 Starfire GT
located at the Red Observatory. The camera was an SBIG STL-4000xcm.
The scope is mounted on an AP 1200 mount.
The AP 1200 is mounted on a Pier-Tech 3 Adjustable Telescope Pier within a Star Traveler Mobile Observatory.
The aforementioned clouds forced me to tweak the setup for a couple of hours before I could start imaging. It helped with the tracking.
Thirty images were collected by there was an unusual guiding problem. The guider would apparently jump once and then settle back.
This led to many of the images have dual everything. I used the best and processed it out as well as I good. You can see little dot artifacts.
The second image used the six best images that had no guiding issues. I hope this was due to my misunderstanding dither guiding in the software.
The image was guided with the interal guider at 20 sec intervals.
The image was collected using Equinox Image.
The image was processed using the 64 bit version of iCCD.
i The bottom three images indicate the location of the M86 Cluster and come from a plate solve at astrometry.net
M86 is interesting as it has a blue shift.
It is traveling toward the planet Earth.
My last attempt at the M86 can be found here.
