This Smarteye eyepiece is very interesting, thank you. Do we know the cost ? It sounds like it stacks live images the way the Seestar does but for viewing only, not photography, if I understand well. It certainly would make a good addition to an observing kit, if it works they way it is advertised....

Nice work Pedro. I am always a fan of your last four light image composite. It shows me most of what is going on at a glance and that is important on cloudy days like today when I could not observe or image the Sun for myself.
Thanks.

Re: 393.3nm K-Line imaging session w/stop down mask.
If seeing supports it, what happens if you image with the full aperture, do you observe a large decrease in contrast ? What is the the ideal focal ratio for k line imaging ? If you image down in UV at f6 (the native focal ratio of this scope) then the image is full of spherical aberation, which res...
