The Sun in H-alpha with a Mintron and M31/32 with a Sony DSLR
A Mintron with the lens assembly from a x3 Barlow was used with the H-alpha PST to capture images of the solar disk and prominences. The two resulting images were combined in Andrew Sprott's Flexible Image Combine software:
Sunspots AR1101 and AR1102 are visible
Sunspots AR1101 and AR1102 are visible
The Sony DSLR was used with a bright Moon in the sky. A 70-300 mm lens was used at 300mm focal length and f/5.6 and ISO 3200. The result is a stack of 30 x 13s exposures:
