Solar filter for Celestron NexStar 6SE

Solar filter for Celestron Nexstar 6SE

Solar filter film:

• Baader Planetarium AstroSolar  film OD5 (for visual observation and photography) or equivalent

General print settings:

• Layer height: 0,2mm

• 4 perimeters

• 4 solid layers (top and bottom)

• Infill: 15%, gyroid

Supports are needed for the filter holder and the filter cap. See screencaps below for placement:

I printed the filter holder in ASA for best resistance to UV and durability. ABS or PETG will also work, but avoid PLA, unless you want your solar filter to melt in the sun heat ;)
I printed the filter cap and inner ring in PETG, as I find ASA fumes too unpleasant (and toxic) to breathe.
I used an A4 sheet of of Baader Planetarium AstroSolar  film OD5 (for visual observation and photography) to create the filter. 

Here is how I proceeded to build the solar filter. 

Leave the AstroSolar film between its 2 protective sheets and use a sharp X-Acto knife to make a clean cut without ripping it. This film is expensive, you don't want to ruin it!

Place the inner ring on the protective sheet to use it as a cutting template.
Cut the filter along the outside of the inner ring part.
Remove the top protective sheet you just cut.
Apply office white glue with a glue stick on one side of the inner ring and then carefully position it on the AstroSolar  film.
Carefully slide the assembled filter into the inner groove of the filter holder.

Note: Be gentle with the 3 mounting brackets when installing the filter on the telescope. These are relatively fragile and will break if forced.  The filter can stays in place without the brackets, but always make sure it is properly secured to the telescope and cannot fall when observing the sun.

NEVER POINT YOUR INSTRUMENT AT THE SUN AND NEVER OBSERVE THE SUN WITHOUT APPROPRIATE PROTECTION!
