Hi Ian,

Drift is a good option. Driftscan software can process your capture. Please record for about 1 minute before and after the mid-time given by the Interactive Map of the Paris ‘Lucky Star’ prediction

Avoid saturation at all costs. If you can’t apply a ‘many-holes mask’ as suggested in the last-minute advice (above), try your R or SII filter with a brief exposure time. A H-alpha would attenuate the light, if available. A small amount of defocus is fine.

Take darks and flats.

Good luck,

Alex (in Alicante)
