    My first H-Apha telescope. I’m totally amazed with the results. A little learning curve but well woth the time. Posting my images on our towns forum brings nothing but praise for the wonders aquried. Only complaint is i want bigger although this is more than adequite. Did i mention great customer service. Thank you Faye

    Wow, just wow! Jaw-dropping images I can’t believe what I’m seeing, not often do I get way more than I expected. I called customer service for an upgraded blocking filter while the scope was on order, and they answered immediately and quickly accommodated me, fantastic service!

    equipment however i have not had the ability to use the telescope as of yet.
