LVAS all,
Our "Observers Challenge" for June will be M-13. We will be looking for the illusive "propeller" within M-13. I have only read of two observers seeing the three dark rifts radiating out from the center. See my sketch of Lord Rosse's sketch of 1850.
WSH brought this up in an article of "Deep-Sky Wonder's" in 1953.
We wil add another "field" with two very faint objects. We will first locate, spurious M-40 and look for the "very faint NGC-4290 and the even fainter NGC-4284 at 14.7 magnitude. I have actually viewed both of these galaxies from my backyard with my 10-inch...see sketch. The challenge will be to just see both of these very faint galaxies. I actually have notes on both.
On April 3rd 1994, Tom English and I observed both galaxies from my backyard. We could easily see NGC-4290 with the GWU orange tube Celestron C-8, but we could not see the 14.7 mag. NGC-4284.
We could see both with my 10-inch reflector. Averted vision was required to glimpse the fainter NGC-4284, but we could not hold it constantly. We observed that night from 11:00 PM till 3:30 AM local time.
Good luck with the June objects.
Roger
