from pixelemon.optics import WilliamsMiniCat51
from pixelemon import Telescope, TelescopeImage, TetraSolver

TetraSolver.high_memory() # IMPORTANT <----

sensor = IMX174()
optical_assembly = WilliamsMiniCat51()
telescope = Telescope(sensor=sensor, optics=optical_assembly)

img_path = Path("./local/2025-10-17-021315.fits")
image = TelescopeImage.from_fits_file(img_path, telescope)

image.crop(10.0) # optional
solve = image.plate_solve
