This is only one frame of an AVI, but there is something strange: a bright object can be seen which does not appear on the other frames of the AVI, nor does it appear on any sky chart I consulted.
I wonder what it is, maybe a piece of space junk ...
Here are the collected opinions of several astronomers.

Simon Smith carried out (THANK YOU Simon !) a thorough investigation (see the opinions file) and issued a ZIP file with the 4 frames mentioned in the 'Opinions' file.

First time autoguiding, with the guiding 'Lidl' Skylux scope on top of the LX200 OTA.
The autoguiding [K3CCDTools and LX200] worked nicely but I had made some errors:
there was a hot pixel in the FFT where the guide star was and I assume that mixed up things.
Also I had not mounted the guide camera correctly East/West so I need to work on this too.
Alas the clouds came too soon so I had to quit before I could make the necessary adjustments.

NGC 2685 is an unusual lenticular galaxy in the constellation Ursa Major.

The 'Seven Arrows' asterism


Seven Arrows asterism
April 5, 2007 20:16 - 20:48 UT.
Seven arrows is an asterism; location RA: 10:50.6, DEC +56 08.
In Sky and Telescope May 2005, page 78, Sue French describes it as a flat boat with a billowing sail, perhaps a Chinese junk.
Others call it a Broken Engagement Ring with the brightest star as the diamond.
Pierre Borel styled it as a bundle of seven arrows representing the United Dutch Seven Provinces [as a Dutchman of I course I prefer this description].
I have dedicated this image to Sue French for her inspiring deep-sky wonders articles in Sky and Telescope.
Imaging: William Optics Zenithstar 80 ED II APO, f/6.8 [focal length 545 mm] with 5 cm extender, Astronomik LRGB-filters; ATK16IC b/w camera, K3CCDTools.
Exposures: Luminosity: 30x10s + 5x120s; RGB 15x10s; autoguided with SC3 camera on LX200.

You see the 3 belt stars, the Flame Nebula, the Horse Head Nebula and on the left a vague outline of Barnards Loop: that was my goal.
Alas the trees won this time, so I captured only one frame [hence the noise]; next time I hope to do better!
