Description

This is my first guided project which occurred over four nights.

this is als my first attempt at imaging with guiding and multi sessions! this took a lot of work!

took these back in April and just now getting the processing where it looks decent.

lights. 354x 120s

flats. 40 or so per session iso 100. 1s

darks. 40 or so per session iso 800

bias. 200 iso 800 and iso 100

focus was set manually using the bahtinov mask. i never readjusted through the night. something i will need to work on as temps dropped enough over the session that it looks to have affected focus a little.

processed these in astropixel processor and photoshop
