Location: Atacama Desert, Chile

Session duration: 2 nights

Sky conditions: Cold and stable atmosphere, seeing ~8/10

Instruments:

• 100mm apochromatic refractor
• 300mm Dobsonian reflector
• 250mm Dobsonian telescope

Targets:

• M33 (Triangulum Galaxy)
• Albireo
• Polaris
• Perseus star field

Observation notes:

Transparency improved after midnight and allowed longer visual work on faint deep-sky targets.

The larger telescope resolved dense clusters cleanly, while the refractor was used for wider fields and comparison views.

A long visual sweep and one test exposure suggested a very thin dark line crossing part of the star field, but the effect could not be reproduced consistently.
