First attempt at solar scan 21st Sept 22

Post by Alun_H »

Today I tried my first attempt at a solar scan in Ha using my Lhires III with 15um slit and 2400l/mm grating on a 120mm f/5 achromat stopped down to 60mm f/10. Because of the glass mirror slit I placed a Baader ERF over the objective limiting me to the Ha wavelength (have a neutral density filter on order) so as not to break the glass,used 3x rate on the handset of the CEM60 to force the scan (and beat the clouds). After using Solex reconstruction software I used Astrosurface to sharpen and rotate to correct orientation,still got plenty to learn ;)
