Description:
25x: Not visible. Two nearby stars with mags 8.9 and 9.4 were barely
visible, so LM in the eyepiece must have been very low.
48x: I think I saw it for a moment, but lost it very soon. Later, I
couldn't find it even with averted vision.
79x: Very faint nebulosity 1'30" in diameter. After some time, I
couldn't see it directly anymore, but with averted vision, it was
visible as very faint fuzzy, 1'45" in diameter.
The cluster was 18 deg above the horizon.
