Simple collapsible, pop-up light or Dew shield for dobson telescopes

The precautions needed to be taken in the nights of stargazing are notoriously two: The shield of any stray light that could be inserted in the optical observation path, The isolation of the inside of the telescope than the outside air currents that would promote the formation of dew condensation on the primary and secondary mirrors. There is also a third trick,

Construction of a"tall" telescope Dobson "Light" 300F6 ...with disc brake – PHASE 1: realization

300F6 “LIGHT”: Mission (equilibration) impossible?….A solution is to equip it with a disc brake! From years, in his beautiful box taped ZAOT (the brand of my favorite aluminizer) I had that mirror Ø305 F 1830 unused. I had bought it for a short time before because it was "gray", i.e. with a good parabolic surface, but happened “among head and neck" (like we say in Italy meaning "by surpise")”, to a “mirror

Portability of DOBSON ? = Transformation in WHEEL BARROW !

My biggest Dobsonian is a 14 "F5 in homebuilt 2003 following the directions of the note "Bible" by Kriege / Berry "The Dobsonian telescope" with unobtainable constructive shares in the book tables, but I have inferred in relationship proportional to the diameter of the primary, with obvious transformation from Anglo-Saxon measures in metric measurements. The result was
