It also provides power to the cute little 1x Rigel Quik finder, and to a fan which cools off the primary more quickly. With the fan on, images were disrupted, so once the mirror cools, turn it off. I would have liked to have seen a built in eyepiece warmer as well. The biggest advantage to the scope is the ease of movement, which really does put the whole scope out of mind while star hopping, there are virtually no limitations in movement. You can stiffen up or loosen movement using various waxes or polishes such as RAIN-X. Additionally, the base can be placed on any surface, unlike a regular dob.
Planetary performance is exceptional, and wide field views the same, with true pinpoint stars.
M81 and M82 looked particularly nice and contrasty in my suburban semi-light polluted skies. M42 takes on the familiar powerful greenish appearance, with all 6 stars in the Trapezium easily noted. On Jupiter, there is a wealth of detail, with contrast lessening a bit after 300x as expected, but crisp, high resolution maintained right through 400x and beyond. A minor disadvantage to the scope is that you need two hands to carry it, and it's base from location to location. Lastly, and I find this an advantage, you need to sit down to use it, unless you are under maybe 12 years old.
