SPN - CONSTRAINTS
My list of the constraints :
- It is not possible to start working right away, but I can brush up my theoretical knowledge.
- I don't have many tools, just a basic set.
- The main observing site is about 25 km away.
- It has been a long time since I made a mirror.
- I live in a windy and moist area.
- Mostly medium and bad seeing, seldom good or perfect.
