Optimum magnification for a telescope with observations of M107, depending on the aperture of the telescope (D), is about 0.4D-D. Higher magnifications of course add details, but lead to a strong drop in the brightness of the image, making it difficult to observe.
The best month for observing M107 is June.
For observers in the northern and middle latitudes:The nights in June are very light, so try to observe M107 also in May and in July.
Of course, these months are also not very dark, in addition the object is at midnight not at its highest point, whichprovides the least exposure and atmospheric distortion, but the sense is still there.The farther south the location of your observatory is located, the darker the sky will be
