Hi Gina,

came across your profile in a few posts and thought you'd be the right person to ask, I'm looking to buy a cheap lens for Christmas to get started with imaging things like andromeda galaxy and Orion! I have done a lot of poking around and have come across lenses such as sigma 70-300mm and a few super takumar lenses. (My dslr is unmodified). I was wondering if you had any suggestions of lenses? With maybe a few examples of what can be achieved with them? 

Thanks so much ?
