It was pouring with rain as I left the house to attend a music session so I wasn't anticipating the clear sky that met me on returning home. Although it was late the transparency looked too good to waste so I found myself embarking on a post midnight spell of imaging. The selected target was NGC 5033 in Canes Venatici. Though it has a bright center the outer arms are relatively faint so I opted for 10 minute subs and was able to obtain 15 with no trouble from the guiding this time. Details: 10" f4.3 Newt. 15x 10minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
