The day before yesterday I examined Mel111 in Coma Berenice with 7X50 binoculars. Quite impressive, as the old binoculars from the seventies has a whopping 11 degrees Field of view. ( and stars like "ghosts" at the very edge of course) The whole cluster fit in comfortably.
Yesterday I went out again, this time with my 102 mm F5 Startravel refractor to have a closer look at Mel 111. I took my sketch-bloc under my arm with me.
The sketch is made through a 24mm Panoptic giving 21 X and a Field of view of 3.2 degrees. The four visible double stars in the sketch were examined with 45X though. In order to find the fourth double star you'll have to click the image and enlarge it. The cluster was observed through a zenit mirror.
Enjoy and thanks for watching

Hello John. A nice sketch of Melotte 111 as seen through your 102 mm F5 Startravel refractor telescope and I think I can make out the fourth double star in the upper left at about the 10 o'clock position using the click up magnification. Thanks for sharing this fine artwork with us on here John and keep looking up.

I love your sketches John!
I'm glad you are enjoying that 102 Startravel, I may pick one up.
Thanks!!
Nice if you want to pick one up, but if you are used to perfection, this may not be your favorite choice. I had to do some work on it myself to get it to a satisfactory level for me.
In this regard, read: https://theskysearchers.com/app.php/art ... irst-light
Not all of them are like that, I have read reviews that never mentioned the aberration I came across in my sample. And seen perfect and imperfect testreports. Apparently the long journey affects some specimens and not others.
Most of your Plössls will deal with the F5 light cone.
Once all right it might surprise you how easy you leave other instruments inside your home!

Great work with the new scope and a lovely observation and sketch, certainly VROD worthy. Congratulations on winning the award!

Very nicely done John. Your sketch is great and congrats on the well deserved VROD. Mel 111 is a very interesting cluster indeed. At our dark site it is easily naked eye, and during periods of good seeing I can make out some individual stars with the naked eye as well. Plus for DSO folks, there are some dimmer background galaxies mingled among its stars as well.
