Quote:The Horsehead has been seen through a (H-Beta filtered) 60mm, so I'll believe you, when you bag it with the 10"...
There's even a credible observation of it in H-Beta filtered 8x42 binoculars (LOTS of attention to details in preparation for the observation and the description of it, that's why I believe it).

Quote: Interesting articles by Stephen Waldee on the Horsehead Nebula found at his site located at this link. I believe it is Jay Reynolds Freeman that Thomas is mentioning though I am assuming and assumptions, like meat cooked by a 18 year old can be dangerous.
Quote:The first time I ever sought out the HH was with a 4.7" refractor and UHC filter, from my backyard in a small town. It was a tough catch, appearing as only a formless notch in IC 434.

Quote: The brightness of IC434 is similar to that of the Veil.
Quote: Quote: The brightness of IC434 is similar to that of the Veil. I beg to differ. It must be considerably fainter. The Veil (eastern half) is easy as pie in any of my telescopes, even unfiltered, but I've never seen a hint of IC 434, despite looking for it on some very good nights in the past.Clear skies!Thomas, Denmark

I meant the unfiltered view. Then again, I don't usually check both on the same night. One thing that I have noticed is that IC434 needs some seconds to materialize, but once it appears it does seem similar. One possibility is that the usual practice is to locate first Zeta Orionis which appears VERY BRIGHT, possibly ruining some dark adaptation, and then IC434. Hence the "delay effect" in detecting IC434. The area has many stars much brighter than those around the Veil. Also, the fact that I usually see IC 434 about 20 degrees higher in the sky than you may also play a role. IC434 (and the HH) are quite a strange case. Walter Scott Huston mentions that IC434 is visible in 60mm refractors. I once (only once!) spotted it (without a filter) with an 80mm refractor. Yet usually it is tough in a 10" reflector. Then, once spotted, makes you wonder why you couldn't notice it in the first place.I have to admit that the HorseHead is one of my favorite (if not THE favorite) targets, and this is the reason I have analyzed its visibility (or lack thereof!) so much!

Quote:Does anyone have thoughts on an ideal exit pupil for viewing the Horsehead?
Quote:Thanks carol for the amazing sketch. I can't wait to give this a go with a near identical setup at home. Likely a tad more light polluted but will give a great representation.
