Intelliscope, method of use


First report having had some problems with the Intelliscope after the first night that no longer worked at the super-perfection, probably carried by hand, not quite delicate, on the evening of the trip, led some incoordination in the encoder system. The "warp factor" in fact, the reliability index with which the object should appear in the eyepiece, was a lag of a few points below zero. If the first evening I obtained a pounteggio of 0.1-0.2, the next time even touched 1.4-1.5, and the third star with a maximum of 0.4-0.5, still acceptable. However This problem is almost irrelevant, given that I used as eye "finder" also the Hyperion 13 mm at 93x.

Observing from home almost all the time spent behind the telescope during the observation, put it on the terrace is a moment. Then taking a little unfamiliar with the pre-alignment is to be effective enough for me very little:

* put the pipe, 3 / 2 *
lead in the eyepiece (in my case the B / TMB 5mm to 250x) a star the list and press enter, 30 seconds / 1 minute *
bet another star, 30 seconds / 1 minute

At this point I'm ready to select any object, moving the tube hand to bring the target in the eyepiece is varamente a game, you can go from two horizons in about ten seconds, not to mention a portion of the sky in a constellation so he loses any utility list objects arranged in a sequence that would not earn that much time.

In practice I have always looked for categories of items grouped by constellation (nebulae, open and globular clusters, galaxies, ...). To make a tour of the galaxies of the Lion, for example, I simply selected the list of sull'Intelliscope gx for the precise constellation and I followed the order set. I do not know how this is some random sequence sets in order the nearest objects: a diced, at the right half of a degree there is a gx, a Tocchetto the canvas down and here is an 'other, and so on ... the same goes for a while all the other items category.

As for the scan I used the same method: a 48x or 93x when the object-centered coordinates, I looked in and saw this item now, 2-3 seconds. This is true for 95% of report objects, all identified on the first try, easy to direct vision. This is probably why I never tried to object to the limit ... just the globular cluster NGC 3156 and a handful of other galaxies.

When he is not the objective individual immediately after the first glance, and even after about ten seconds, proceed viewing area in averted vision, in which case do not know where to look for the least complicated things, but where I can elaborate on some information (this applies to selected items on the book by Albano) is definitely easier.
The precision of pointing which allows in many cases to look directly at the object already 93x facilitates the task, not always for convenience, having a pointed object, change the eye (especially with respect to galaxies), opting instead to make a dozen objects at 48x and maybe another group all at 93x and vice-versa.
