Congrats! That is definitely a nice antelope. Now that you got it back, I assume you traded your taxidermist your deer for your antelope? When you get a chance, throw a picture of your antelope mount up here.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
