Hi! I'm Johnny, one of the devs behind this game. Sorry to hear about the crashes, but unfortunately we had to close our studio because the game didn't sell very well so we can't keep supporting the game any longer.
About the constellation puzzle, you can press a key (by default is TAB or one of the triggers if you are playing with a game pad) so you can check the constellations whenever you want while you are not using the telescope.
And yeah, there are some typos in the writing because some of the posters and written resources where made by me (a spanish fella with its english limitations) after the official translation we paid to a proffessional team of translators so... my bad :(
