102mm f/11, 62x, Bortle 6, SQM-L 19.3, Seeing 2/5
Beautifully separated, relatively tight with well visible difference in brightness. Points directly toward Messier 1 and can be observed with it in one field of view. Very nice!
|
|
120mm f/5, 48x, Bortle 6, SQM-L 19.2
Nice, evident double near Messier 1. Easy to split with almost equally bright components.
|
|
152mm f/5.9, 69x, Bortle 6, SQM-L 19.3, Seeing 2/5
At 49x just so, at 69x easily separable. The fainter component appeared a little warmer in terms of color. Great view together with Messier 1 in the field of view.
