Status of the Lowell Discovery Telescope (LDT) and assessment of the image quality at the focal plane

The Lowell Discovery Telescope (LDT, formerly known as the DCT) is a 4.3-m telescope designed and constructed for optical and near infrared astronomical observation. We present the evolution over time of LDT's image quality and ways to improve it, upgrades to the instrument suite, and lessons learned from operating during the pandemic.
