The Orion(of California) 114mm f/4 Newtonian on an EQ-1 mount, and nearly identical to your Tasco(Tanzutsu) kit...

The Orion kit is identical to the Sky-Watcher "Skyhawk" 1145P...


The telescope is configured for low-power, wide-field views.  With the aid of 2x and 3x barlows, you can reach the higher magnifications associated with lunar, planetary and double-star observations.

However, the focusser of the Tasco telescope, the visual-back specifically, is of the .965" format.  Current, standard, extra eyepieces are of the larger, 1.25" format.  You may find it difficult if not very in integrating the newer, 1.25" eyepieces with the telescope.  The drawtube of the focusser appears to be able to support the use of the 1.25" format... 


...but the opening of the visual-back, where the eyepieces fit and are secured with thumbscrews, is .965" in diameter.  It can be removed, but finding a 1.25" visual-back to fit the drawtube may prove more trouble than it's worth.  There are extra .965" eyepieces available online, yet are few and far between.  The .965" format has been abandoned for a few decades now.

Incidentally, I do not recommend f/4 Newtonian kits, whether a Dobson or tripod-mounted, to those first starting out.
