Description

After captured Leo Triplet, M66 seemed a good target for my 11" SCT. The shape of M66 looks like an Arabic numeral 6 in this image. Did Charles Messier see this way and listed it #66 in the catalog? The data was collected during the period of below-average seeing. I also collected Ha 48 frames of 900 seconds, however, I couldn't blend Ha into the Red channel due to lack of details.

Any C & C are welcome

Thanks,
