C/2023 H2 (Lemmon) 2023-Oct-27 Dan Bartlett

- C/2023 H2 Lemmon October 27, 2023 -

Went with 30 second exposures in an "attempt" to beat out the heavy moonlight (It was setting though). The plasma tail is faintly visible after stacking 101 subs. Not disappointed though, the tail appears to stretch out off the field.
