Hi Anu, like you, I joined today after reading the forums as a guest for a while.
I was given my astromaster 130eq md from my wife for Christmas.
And yes like you, I also a bought a t-ring to go with my barlow so I can take pics. After taking a few pics of the moon I found that while looking through the camera, and even though the moon appeared in focus, the photo was not. See the link below for the reasons why the photo was not in focus and a few tips to make it in focus.

If you haven't already ( I haven't been able to yet cause I'm a noob), I suggest you start practicing polar alignment to South Celestial Pole (SCP), or Sigma Octantis as they like to call it. Just google there is plenty of info on it, although quite confusing for a novice. If the scope is not polar aligned, lets just say the photos aren't that much chop. Star trails is the obvious problem as well as focus issues, to name but two. I found if I took a photo for say 15 seconds, the star trails were passable, but detail was low.
I also found that I may need an extra weight to correctly balance the scope with a camera attached. It wasn't so bad piggy-backed, but once I mounted the camera into the finder, things certainly got messy (again I'm a noob).
I look forward to seeing some of your pics Anu, and good luck with it. It's nice to know someone uses the same scope as myself.
