Hello Everyone, I currently own a small dobsonian telescope and with recent trips out to E. Washington state, i've been curious about upgrading to a more powerful scope. This is the one i currently own: http://www.apogeeinc.com/product.asp?itemid=766 And the one i'm currently looking at: http://www.walmart.com/catalog/product.do?product_id=2684096 My question is. Will i notice a more significant difference in using this one? Or should i spend a bit more for a more powerful model, i want to eventually get into some astrophotograhpy and probably have one that will allow me to do so. I've been doing my stargazing near the LIGO area, It's a great site and soon i will shedule a tour of this fascinating observatory itself. Thanks in Advance.
