Whats The Best Toothpaste

mating screw-down crown

Maybe is the strength of this tool, once very popular with astrophotography. I speak of
LX200GPS 8 "
But then just as it is, leaving out other much more sophisticated and demanding (but alas more expensive).
for Meade Instead, this instrument has remained unchanged for much of the form time, subject to internal or external changes to make the product more efficient.
The worms which control the movements have the particularity to mate with the crown for at least 1 cm and then at least 5 threads are always engaged.
Unlike other systems where the coupling is yes and no by two threads.
This is an advantage not just because the axle load performance is greater with less wear of the mechanical screw / crown. The Meade
designed very well be a flexible stand that keeps in constant contact the teeth of the worm wheel and games operation. Why
Meade has taken these precautions?
Certainly the fact that the tube is mounted in a fixed position on the fork, and you can not move any weight added to balance the telescope. Often
accessories such as eyepieces, filter wheels, and the goal of capturing or guider CCD camera or added to the telescope moving substantially the balance of the axis of declination, with consequent difficulties in balancing the system.
An effective way is to add still more of the counterweights on the tube but on the opposite side to reduce (but not eliminate the problem).
A well designed system can reduce the wear on the coupling, and ultimately have a valid business tool for taking pictures with long poses.

M101

Friday, March 26 I made some fast times despite the Moon over the first quarter and the usual street lights, more than anything not to lose his hand in the use the telescope.

Needless groped nebulae! M101 I chose because it is quite bright and high in the sky.

to about 50 ° from the moon a beautiful globular cluster that does not require much effort, but in the same picture is can see a galassietta of 13.9 in May

Fortunately, the LX200 is working well, you just have to wait for a beautiful evening of new moon with the usual friends in the usual places.

Brinks Home Security Model 5056 Instructions



awakes after a long hibernation

From September Last year, until the first week of March this year, I pretty much stayed in the astronomical sense, because of the weather, a number of personal problems, and finally because the sphinx is just right, not (or do not know how to use).
Then I went back to the old heavy LX200GPS that has shown and still proves to be more reliable and decently autoguiding photographic poses ( and think that I wanted to sell )!

course I would have liked a Mak1 or wait a GM1000, but then I thought it was not worth the price (7000 € are a little a lot) and take pictures is fine so far an older LX200 that has proved effective when the seeing permits autoguide properly. The only problem is if you really want to find a weight XXL
If anything, I'll do a bit of weight lifting to feel lighter!

I had time to capture a series of frames at the head of a horse before sunset and rose during the second exit at Colle del Lys in the company of Saro and Lucio below and attach the results are not perfect because even if lacking other signal, if I can next weekend carrurerĂ² another series of frames of these entities.

For a complete description, I preferred to use instead of the amended EOS350D MZ8pro given that this recent acquisition has given me some problemini. We

Colle del Lys discovered that besides being a "stone's throw" from Turin also offers a decent and sufficiently dark sky, so we are even more motivated to make fast exits the week, but for now we are content to settle down at the roadside to about 100m from the square that is lit by two lamps cursed.
Another novelty of the hill, back down the road I met a cinghialone from fear with two menacing teeth, thank goodness that was more willing to cross the street to load my car!

after 300m but two deer crossed the road in search of food near a group of houses. Very
local traffic in this area, I hope not to find a pair tomorrow extraterrestrials since the area is known for its UFO sightings!
The road is still much easier than leading to the hill Vaccera.

Finally after a long slumber disturbed by various bad dreams I have found the desire to continue to do astrophotography.
