Neutral density filters for evscope/Stellina telescopes?

Mon, 10/16/2023 - 15:03

Hi, folks,

The solar eclipse this weekend got me thinking:: does anyone know if it's possible to do solar observing with the eVscope or Stellina telescopes by putting a neutral density filter on the top of one of them?

Or as small telescopes with CMOS detectors, maybe they can even handle looking at the Sun.  I wouldn't want to try this without real assurance, but I'm wondering if anyone knows about that.

Unistellar sells a somewhat overpriced ND filter for their scopes. If I owned one I'd make one out of Baader solar film and either 3D print a cell or cut up a manila folder and use tape to hand make one.

I would NOT risk burning the sensor out by using it without appropriate filtration!

You'll need a proper solar filter. Unistellar sells one for the eVscope. 

For the Stellina, you could buy some solar filter material and mount the filter in front the lens.

An unfiltered focused solar image would almost certainly destroy any sensor.
