The eye sees only what the mind is prepared to comprehend. Henri Bergson
Quote:Jupiter: Easily the best ever views I've had of Jupiter in my scope. The view was sharp, and a little bit to my surprise, not soft at all. The image was crisp. The bands were visible, but the GRS was not because it was not transiting at the time. Because of the overcast, I was not using my 3" mask, and I also could not evaluate light scatter in this EP. When the weather permits, I'll post a more detailed write up on this EP for planetary.

Quote:What is the 3" mask and what is its function?
10" F/4.7 Modified Skywatcher Reflector, 38mm Orion Q70, 17mm Modified Ultima LX, 10mm TeleVue Delos, 7mm Pentax XL.

Quote:Using a mask on a reflector is like using a refractor. There is no central obstruction....no diffraction spikes. I still see tiny festoons and detail and it takes the irradiation away. If you want to play with flashlights all night, then have a party.
Not doing it right? Sorry Mike, I've been observing for a lot longer than you have, and I know what I am doing. Not everybody does what "you do"....and not everybody does what "I do", but I know what works for me.
Quote:I'll try what you said, which is shining a bright white-light flashlight on a piece of white paper to bring my eyes up to photopic, the appropriate level of adaptation for viewing planets. I’ve never tried that before, so I’ll certainly give that one a go.
Quote:I got a chance to compare images of Jupiter, M42, and Luna between the ES 5.5 and the TV 6mm Ethos last night, and I’ll post my thoughts on this tonight as I have a birthday party for my son to host.
Quote: AFAIK, this trick has been discovered independently by many planet observers over the years. That's not surprising, since it's such a simple thing to do.
Quote:I don't bother with a white card, I just go inside and get some warmth, while I'm at it! Or maybe I leave the porch light turned on. Mostly, I tend to leave it off, as I find the light that leaks into my eye annoying. It's pretty difficult to not get dark adapted and yet not get any light leaking into the eyepiece...Clear skies!Thomas, Denmark
Quote:BTW, I can absolutely recommend a binoviewer, if you're troubled with glare. It cuts down on the light, while increasing the contrast and cutting the noise, because the brain gets twice as much signal.Clear skies!Thomas, Denmark
Quote:Also, I apologize that my report is not technical. I've had a flood of family and friends over on clear nights w/ good seeing so they could look at Jup and some of the brighter DSO's. I simply haven't had the time to sit down and write notes at the eyepiece. In fact, only once have I observed with the ES 5.5 by myself.
My eyepieces are made from the waste product of exploding stars.
