2 in 1 Bahtinov / Twinkle Mask for Dwarf2

thingiverse

This is a 2 in 1 magnetic adapter plate containing a Bahtinov mask for focusing and a Twinkle mask for effects. You only need (2) 6mm x 3mm magnets to attach this adapter to the Dwarf 2 scope. The Bahtinov mask is indispensible for fine focusing. Simply flip the adapter to use either mask. Steps: 1) Place 2 (6x3mm) magnets diagonally on the Dwarf2 as shown and mark them so that we can remember the polarity. 2) Press the magnets into the adapter with pliers making sure the polarity of the magnets hasn't changed. The pictures of Arcturus demonstrate the Twinkle effect and focusing success with the Bahtinov (note the horizontal flare directly in the middle of the star). You could build this plate using no magnets at all especially if you're just using it to check for focusing. Clear skies!
