I would stay away from that particular scope, You would do much better to save your money and purchase something with more aperture like a 6, 8, or 10 inch Dobsonian.
That scope will also do you no good for any decent astro imaging, since it's an Achromat and with the legs extended, it will be even more wobbly than the original mount for any kind of observing, and it will be useless for imaging.
If you have your heart set on imaging you really need to spend a considerable amount more than just 200 dollars.
For deep sky observing you want at least 8 inches of aperture, although you may get by with a 6 inch DOB, In this hobby aperture rules.
For imaging you need a very stable mount with tracking and auto guiding abilities, and either a SCT or a very expensive APO type of refractor or a Newtonian, mounted on a good stable EQ mount. if you choose a fork mounted scope you will need an EQ wedge for imaging,
You really have to decide on what is you main interests in this hobby, before you spend your hard earned cash.
You really should read (getting started with a telescope), that is posted on this forum by Tkerr.
Some folks do very well with a CG5 ASGT mount with a small APO refractor for imaging, but for visual work on deep sky objects you need as much aperture as you can afford, the minimum would be a 6 incher.
Just my two cents worth!
