baffling

The first part of disassembly was just to clean the optics because peering down the tube saw specks of dust but until it was apart and a close up look, revealed this grotty mirror I'll be giving it a good clean with basic gentle hand wash and some demineralised water that I'll pick up from bunnings...

Because I reside in Sydney CBD area, light pollution is high and it led me to research on ways to reduce unwanted light entering my scope. A bit of research led to the idea of baffling and flocking inside the tube.

The geometry was solely taken from this online generator "Newt for the web"

The profiles were extrapolated from the online calculator and laser cut out of 3mm mdf wood with a notch to clear the seam joint of the optical tube. The wood was given a spray of matt black by none of than the good old Australian export spray paint.

Aligning each baffle according to spec with three marks inside to ensure each ring sits true and parallel(perpendicular?) to the length of the tube. They were cut so it was a nice snug fit although they will still be glued in later. What one thought would take 15minutes to align 10 or so baffles... took about 2 hours
