      Description

      Finally able to complete an image after multiple weeks. Weather is typically very cloud here during this time of the year and I was not able to complete any of my targets.
      I did manage to get some data on M85/NGC4394. I have always liked this field and surprisingly there are not many images . The NGC 4394 with its classic barred spiral presentation and shells of M85 look spectacular.
      I attempted 15 min subs on this to see if I can get more depth. There is quite a bit of extended signal,. but I couldnt pull it out without the image falling apart. Color data is quite weak (I shot it while last night with the moon in play). I think the darks are not matching well and it is resulting calibration artifacts. I Will retry calibration once I shoot new darks.


      L - 60x15 mins
      R/G/B - 15x10 min subs / channel

      Version D: Reprocess with the correct calibration frames

      C&C welcome
