IC 2087 - Bright Diffuse Nebula vf, vl, quite oval in shape. Best without any filters, though the UltraBlock seems the best of all the filters. You might have to "wiggle" the scope a bit to get this illusive object to show up.
I viewed IC 2087 as part of my observations for the Perseus/Taurus piece in the January 2000 "Astronomy." I didn't notice an oval outline in a 12.5-inch scope. It was circular, and 5' across. More striking was the lack of stars down to 15th magnitude. At that time, I posted a chart generated with Megastar that shows the dark nebula at:
It's over 400K; sorry.
