Maginitude with my 'scope
Hi all,
Just a quick question regarding magnitudes. Some of the nebulae, star clusters etc give me a magnitude of say... 7, which i believe is relatively low? The lower the number the brighter it is? (-3.90 would be brighter than 3.90?)
Just wondering if someone would be able to tell me what sort of magnitude of star i could see up too with my scope? (Celestron Astromaster 70mm refractor)
