Product Description
Brighter than a Cheshire eyepiece for half the cost! This tool is
excellent for aligning the mirrors in Rich-field and fast Newtonian &
Dobsonian telescopes.
excellent for aligning the mirrors in Rich-field and fast Newtonian &
Dobsonian telescopes.
Look into your telescope through an our collimator and you see a bright
white circle surrounding the image of your eye's pupil, making it easier
to center the primary and secondary mirrors, which is especially
important for aligning rich field and fast Newtonian and Dobsonian
telescopes.
It utilizes a flat reflective surface that gives a multiple reflections
through the optical system. An instruction booklet is included.
Quality aluminum construction with black anodized finished.

here in holland there was a special offer; camera, camera bag, and spare battery look for the best deals in diverent stores!
Well i was just passing by here searching some information and came across this important information and i don’t know much about this mirror so i will keep looking for more information.
use mirror mastic, its sold at most hardware stores.
to all you who say he has no chance of solving it if he takes forever to open the box, take a look at 2:25
Where can I maybe find this at?

If the focal ratio of your Newtonian is f/6 or greater, you probably don't need anything more than a simple sight tube. Orion supplies a nice little one free with every Newtonian they sell. Alternatively, you can make one yourself from an old 35mm film cannister by cutting off the bottom and punching a hole in the top.
For shorter focal ratio Newtonians, you need a Cheshire eyepiece. The one Orion sells works just fine:
Laser collimators are useful only for double checking the collimation of scopes already collimated with a sight tube or Cheshire. Used by themselves, they can easily mislead you.
Collimating a Schmidt-Cassegrain is a totally different process, and is done with a star, and needs no special equipment, though replacing the collimation screws on the secondary with Bob's Knobs makes the process much easier:

Hello,
is there a simple way to replace the gradient background image with a repeating tiled image? I noticed that when the window is re-sized it goes out of alignment.
I love that it is possible to replace the header text with an image in the WP Dashboard – but I didn’t see any similar option for backgrounds.
Thanks

Interesting story: My parents saw a marriage counselor when I was young and this idea of the two “kinds” of sorry was one of the most visited topics in the discussions (as I heard my mother telling others about the sessions). As I have gotten older, this paradigm looms more important in my dealings with others (and my own introspection) because it is so foundational to how to deal with one’s owns shortcomings. How to deal with mistakes depends greatly on the one whom you feel bad for hurting – if you feel bad for hurting them at all.

hui cok iyi biri onu da soyleyim. hocamin da bir collimatori oldugu icin taniyorum adami.
cool science/math
look and see for yourself.
this is why we always tell people to visit local astronomers and see things for themselves before committing to a purchase. had you don this you would know it depends on the eyepiece focal length (i.e. magnification) and the size of the eyepiece's field.
Let x be the required distance in mm.
1 / 13.0 + 1 / v = 1 / 12.0
v = 156 mm.
The image from the objective needs to be at the focus of the eyepiece to produce a final virtual image at infinity.
1 / (156 – x) = 1 / 25.0
x = 156 – 25
= 131 mm.
Only if we one day created a ship that could go 100,000x the speed of light. Then you would get there in about 10 years.
aslinda benim derdim bunlarin bisi yaptiklarindan daha ziyade bu kadar ferromagtism olayinin originin well-understood olamyisi. ama bolye soyleyim ki yeni ogrendigim seylere gore scnience’dekiler cok buyuk konusuyorlar cunku stoner modelinin dogrulugu hic kimse tarafindan cokta isbatlanmamis bir olay. bunlar ise onun dogru oldugunu idda ediyorlar. ama hui hala direniyor ve pek bir sey olmadigini solyluyor. ama ben gene bunlarin ikisini iyice karstirip anlatmaya calisirim. belki bir toplanti da yapabiliriz bunun icin.
Back in May 2009, the Hubble Space Telescope got its final tune-up . The seven astronauts of the STS-125 mission flew to Hubble on space shuttle Atlantis, grabbed the observatory with a robotic arm and pulled Hubble into the shuttle’s open payload bay for repair. They then commenced an intensive servicing itinerary that spanned five spacewalks. Although the mission was not without its hiccups–some of the instruments were never meant to be repaired in space and proved difficult to work on– the Atlantis crew left Hubble revitalized , with one camera repaired, another replaced altogether, a new spectrograph installed and a slew of old or failing parts swapped out.

lmfao XD i love how she winks at the old ladies at the end xD I would faint xD
where u have it?ß
Thanks goes out to Doc Craig at Discover Chiropractic for keeping me in alignment!
can i keep my eyse open so i know what to do next
I broke a mirror today.
