Note on observing color:
I am red/green colorblind and while I can see color, it is very difficult to label what colors are observed.
Requirements:
To receive your observing certificate and pin you must split 50 of the double or multiple stars on the list with a binocular. Any size binocular or combination of sizes, including mounted and image stabilized may be used. Observers using large, mounted, or image-stabilized binoculars are encouraged to observe some of the fainter and closer pairs on the list. A bino viewer on a telescope is not permitted. If you have questions about whether your instrument meets the observing requirements of this program, please contact the Program Coordinator listed in the heading before you begin.
Your 50 double star observations must also include observing and splitting the same five pairs with your naked eyes as well as your binoculars.
Your double star observation log for each target must include:
The designation of the double star and the constellation in which it is located.
Date of observation.
Time of observation.
Your geographic location. (including latitude and longitude)
Sky condition: seeing and transparency.
Whether binocular-only or naked eye and binocular combined.
Size of the binocular (magnification and aperture) used to make the observation and include whether:
HH (handheld)
TS (temporary support)
MT (mounted)
IS (image stabilized)
O (other - explain)
Brief description or rough sketch of the double star and other prominent features seen in its immediate neighborhood.
Location for all observations:
Bortle Sky:

Longitude:

Latitude:

Elevation:
644 ft
The first 51 entries below were submitted for the award. I have continued to work on the remaining doubles. The log for all completed binocular double stars is in the spreadsheet at the bottom of the page.
Sketches of the binocular double stars are not required.
After I completed the required number of observations I realized that I enjoyed finding the doubles with binoculars. Since some of the doubles are closer than my 11x80 binoculars can easily split, I've also resorted to using Barska 30x80s. Since the Barska's have a narrower FOV, the finding is tougher, but the splitting is easier.
All 120 were completed on 1/11/2014.

Binocular Support: NE & MT
Observations Naked Eye:
Very hard to see from Broemmelsiek! If the moon would have been up it would not have happened. I got it, but I had to work. Upsilon & Iota Gemini were both easier to see than the double.
Observations Binoculars:
Gemini was high in the sky and on the meridian, with no moon in the sky when the double was viewed. I can't tell which of the two stars is brighter, but they are on about a 180 line with the alt/az mount.Upsilon and Iota Gemini are in the same FOV as is an interesting trapezoid of four stars above the double in the binoculars.

Observations:
Easy to find because it is left most foot in Gemini. Difficult to split, more because of the dimness of the secondary than the distance. The secondary is at about 85 degrees to the primary, but dim, dim, dim. Three faint stars are to the right in the field.

Observations:
Tough one to find! It is located in a part of the sky I don't know much about and it was straight up. I ended up flat on my back on one of the pads to find it.

Binocular Support: NE & TS
Observations Naked Eye:
You can convince yourself that you can see anything. I'm pretty sure I can see both stars in the pair below Acrab. The stars seem to fade in and fade out at different locations and that's why the seem to be different stars. Grant Martin probably thinks I'm crazy (Bino Double Star certificate #18).
Observations:
If you can see them with naked eye, then certainly they must be far apart, so much so that it would be easy to think that they are not a double. The secondary is slightly dimmer and a different color, 185 degrees from the primary.

Observations:
An experiment from the first night viewing of double stars with the 11x80s. A test to see how little separation is possible. The double appears as an elongated blob rather than a sphere, running 30 degrees to 210 degrees. No real separation, but I can tell it is a double and the brightest star in the field. There are 6-8 other stars in the field, but nothing very memorable.

Observations Binoculars:
First double should be Alcor and Mizar. Easy to split with binoculars as Mizar closer companion too. Alcor is about 210 degrees from Mizar and Mizar's closer companion is about 180 degrees from it. Mizar is much brighter. HIP 66198 is in the same field and fairly bright too.

Easy to find starting at Cor Corli and heading towards UMa. The two stars appear to be of almost equal brightness with the top star being a touch brighter. There is a good separation at an angle of about 200 degrees. A chain of four stars runs from below and to the left to the right and above.

Observations:
Fairly easy to find between Vindematrix and Bootes. A sucker non-double in the same FOV back towards Vindemartix. The secondary is very dim and averted vision helped see it at an angle of about 190 degrees from the primary. Fairly large split.

In the same FOV as Alberio, one of the best doubles in the sky. A fitting way to end the hunt. This double has two fairly bright stars with the secondary at about 330 degrees to the primary and a very wide separation.
