David K,
What is the best magnification to see the notch in your 9.25"?

Thanks

Generally, I get the best views of it at 58x and 78x in my NexStar 9.25, although I have used up to 98x on it on a really good night. From my dark sky site, both powers will show a little of the "snout", although the form is still fairly vague. In my 100mm f/6, I generally use about 25x and the H-Beta filter (24mm Panoptic) to try and catch a hint of the notch, although it takes a really good night to do this. Clear skies to you.

It seems like I read something within the last year about the magic eyepiece for looking at the HH. I think this was using a low power eyepiece for the brightest image of HH, if I remember corectly. Anyone remember the formula for the correct eyepiece to see the Horsehead?
Clear Skies, Buddy

Barbara Wilson in her article on the "Magic Horsehead Eyepiece" claims that a power that yields around a 5mm exit pupil (5.1x per inch of aperture) is pretty close to optimal for the nebula. Clear skies to you.
