Yello, yea, somewhere we're crossing paths and wires. No offense ever intended.
I wasn't trying to say what I think you understand. Lol
I guess all Im saying, really, if we're perceiving color, then we are not observing Jove with low res, grey scale dark adapted vision. We are still firing hi res, color receptors and may have no need to reset our eyes with a bright light. Actually, it was a question. I've tried this technique and found it distracting. That's all.
Howver. I also take a break and have coffee, too. Esecially during a long session. It's relaxing.
So it's basically this. The rods in the retina are the receptors in low light and are less sensitive to color. The cones are sensitive to colors but need higher light levels and the cones at the center result in the best sharpness. My own discovery of this effect occurred by accident after 10 minute coffee breaks in my brightly lit kitchen many years ago. Every single time I came back and looked into the eyepiece of any of my telescopes, I was absolutely stunned. The OP is about a 1" vs 12". This Will seriously help observers with larger 12" scopes where the brighter light of planets is very saturated and irradiation is severe. The smaller the aperture, the more discipline you need and this is probably what's happening since your Mak is only 6". The basic rule is "planets are bright enough" and here's exactly what it looks like when the effect occurs.
When you come out of the kitchen, the background is jet black as illustrated in the first image left. At this point, the effect is absolutely astonishing while viewing the planets because nothing in the background or around the planet is visible yet. Remember too that the colors we see on the planets are the fuel to the surface contrast. Light does not scatter or encroach into adjacent features. Instead, the edges around the planets including their features appear tack sharp and relatively filled with more visible surface color. As the eye begins to dark adapt (the enemy), the background starts to appear more like the center image. Notice how you begin to see more stars. Now imagine it's a Newtonian and there are diffraction spikes from the 4 vane spider. Because of the effect in the first image far left, your eyes are not dark adapted enough to see the diffraction spikes. But as they dark adapt, the fainter diffraction spikes become more and more visible. This starts to occur in just 30 to 45 seconds, so time is very crucial to get the best planetary views. By the time your eyes are dark adapted, the background becomes worse. Color Contrast starts to weaken, light around the planet is scattered and encroaches on adjacent features. The halo of scattered light around the planets also becomes completely visible and more annoying.
Awwww, what a bummer. What should you do? Keep an 8.5x11 notepad with white paper next to you and shine a white light onto the paper and stare at it as much as possible and continue taking moments to look into the eyepiece. Doing so will help generate the effect you see in the left image. Remember that planets will always be bright enough, so dark adaptation is never needed nor wanted. You should keep white lights on around you at all times. I suggest white LED's and avoid red flashlights at all times as a source of light. LED's are extremely efficient and don't give off terrible heat currents near the telescope compared to conventional light bulbs. There's still another method you can use that works equally amazing. I also noticed it by accident at home as well as Charlton Flats during sundown. In this particular case, the background light is so bright, your eyes are unable to dark adapt. As a result, the background light completely hides any scattered light because the brighter planets don't have a dark background to see scattered light against. With larger apertures, diffraction spikes, halos and light scatter are completely invisible. But, as the sky darkens, scatter and halos become more and more visible and the enemy (dark adaption) resumes.
Then one day I accidently stumbled on a quote by Master planetary observer John B. Murray that described exactly what I had been seeing. He said it best which I shared in an article in 2003 called "planetary eyepieces". "Sometimes it's the contrast of a dark sky and a bright disk that renders details difficult to see, and observations during bright twilight, when planets first become visible to the naked eye may show surface features much more clearly than against a dark sky.
