Meade-Lightbridge-16 diaphragmed down to 170mm

Very impressive results!

Thank you very much for sharing!

Any recommendations about

a) mask - telescope aperture ratio?

b) off-axis angle?

@igotmail2 mask becomes useful with big newtonian telescopes, 8 inches or more. Off-axis should be the closer to the center/axis the better.

Very nice detail.. Must be awesome to have a 16".. the biggest I've used is 10

@mrtapoche1 A mask is a diaphragm for the telescope to contain the negative effects of the seeing.

Nice jop !

What's a "mask"?

[CumputerPhysiscsLab]

@ParaglidingManiac In this case, it is an off axis aperture mask, that stops down the aperture of the telescope, avoiding turbulence effects at high resolution imaging.
