I imaged Comet C/2019 Y4 Atlas from Buford Mountain Conservation Area. The midpoint of the image sequence was 11 April 2020 at 02:58 UTC.
The comet was imaged with a Meade LX-90 200 mm aperture Schmidt Cassegrain, with 0.6x Focal Reducer to provide a 1200 mm focal length, EV-3M focuser and QSI683wsg-8 camera at -15C. The system was mounted on a Losmandy G11G2 mount with permanent pier. System control was with Sequence Generator Pro 3, and off-axis autoguiding with PHD 2. The 60 minute exposure consisted of 12 x 5 minute luminance images, which were processed in PixInsight 1.8 and PhotoShop.
The center of the frame is at RA: 6 48 26.752 Dec: +67 03 17.96. North is to the right.
This is an animation of the comet moving against background stars. Each frame is five minutes of time.
