    I want to welcome you to the EAA forum.

    What is EAA? EAA stands for Electronically Assisted Astronomy (the last time I will type that out. :-)  ) It is the use of a special camera (some are relatively inexpensive) with your regular telescope to see deep sky objects...in color...in detail...under city lights. And most of them can be seen in under a minute.

    Why do I use EAA? Since I do most of my viewing in the city of Louisville near Springhurst, it can be rather difficult to see objects except for the moon, planets, sun (of course) and a few very bright nebula. So, my reason for using EAA is so I can see more things.

    What kind of scope is needed for EAA? Most any telescope that will do goto/tracking will work just fine. You can even use an alt/az telescope mount and get great results.

    What EAA is not? Mostly, EAA is not astrophotography though many of the same techniques are used. Where most astrophotographers will do exposures in terms of hours (sometimes 10-20 hours or more), EAA users will get their exposures in 1 to 10 minutes. EAA is about seeing deep sky objects that you otherwise could not see under city lights. Astrophotography is about creating beautiful images of those same objects.

    So, in the coming months I will share more of my journey in learning how to see the deep sky using EAA.

    Cheers...Warren

    Note: The attached image of the Horsehead Nebula was done in my front yard, full moon, neighbors porch lights on. Exposure was about 2 minutes. I will share more info soon.

    PS...if you have any questions, please ask, but create a new thread for each question. I will be glad to answer and there are several other members who will be glad to guide you and share their experiences.
