M57 : Seestar Simple Spectrum

About this image

Ongoing attempt to obtain spectra with Seestar. This time using a cheap (£20) 40X40mm objective prism. This is a work in progress my next step is to try and avoid screen dump by using the newly available Continuous Shooting mode whereby hopefully spectra can be stacked externally.
