Hi,
When the moon is up I very often will use the standard red filter rather then a H alpha filter. This has the advantage of more light throughput and I can find a guid star while it's often impossible to find a guide star with the H alpha filter.
M1 60 mins exposure with 10 min subs, Takahashi Mewlon 250 at f9.1, ST10XME 1x1 binning. Processed in MaximDL v 4 and Paiantshop Pro.
clear skies,
