New NGC4565

Hi All,
Thought I'd brave the amazing images posted here recently and share my most recent. Starlight Xpress MX716 through an unguided LX90 at f/6.3, 30 second subexposures. I had trouble with flats, so couldn't get rid of some gradients. Comments and suggestions are welcome and, indeed, necessary.

Larry,
Great image - even more impressive that it is unguided.

You can remove a good deal of the gradient on the stacked image with the DBE tool (Dynamic Background Extraction) in PixInsight LE - its free. see:
