Description:
Well the scope is really set up well tonight and even though I'm under urban skies
I thought the "E" component of the trap might be within reach. So I put in my
12.5mm Sebert and at x80 well there it was in and out!! Man it was steady tonight!!
Put in the 17mm homemade plossel with a shorty barlow and it was very plain to see
with direct vision...checked to star charts to verify the position and sure enough
that was "E". with averted vision the whole nebula seem to have little twinkles
just on the edge of perception..definately had direct vision down to mag11 across the fov.
All components were white with varying airy discs, "E" was just a point in and out of direct vision.
