Telescopes

Archive for the ‘bushnell telescope’ Category

My brother and I were recently given a used Bushnell 450 telescope. I don’t think they make them anymore and I know its a lower end telescope, but we can’t get it to work. We pointed it at the moon and turned all the knobs we could but it wouldn’t focus. It just stayed blurry. Either we are missing something or it’s just broken. Any suggestions?

Bushnell is very good about having manuals for their telescopes online, even if the manuals aren’t very good:

This is a pretty generic 4.5" reflector similar to many imported from China past and present. Orion also has manuals online, which are much better than Bushnells. Find an Orion telescope similar to yours, and then download the manual here:

Be sure you have an eyepiece in the eyepiece holder — use the one with the largest number, usually 25mm or 20mm. Try using the scope in daylight on something at least 1/4 mile away. Focusing is very critical with telescopes — there’s only a tiny range where things will be sharp, and it’s easy to motor right past it.

Try to locate your local astronomy club. They’re usually really helpful with beginners.

I have been trying to figure this out for quite some time. Exactly what do i need to connect my camera to my telescope?

I have a bushnell refractor telescope, its model number is "78-9470", and then i have canon EOS cameras. I am not 100% sure if it accepts the 1.25" standard size attachments in the back, or if there is something i can get for that. I have already found the two pieces i ‘theoretically’ need – the t mount and adapter for the camera body and the telescope back. Is there anything else i need to make some ‘stellar’ photos?

really appreciate any help! thank you so much.

You have the hardware figured out, but what you also need is a computer controlled motor to keep the telescope tracking the star or planet as the earth moves around its axis and the sun.

This is the motor drive that was designed for my telescope

With some further research, you should find one that is compatible with your Bushnell.

My grandfather was tromping the backwoods of British Columbia decades before I was born, driven by a lifelong appreciation for nature. I inherited his old Bushnell the year he passed away, and soon set about interfacing it with my iPhone. I was remembering how much I loved that telescope as a kid, how it fit perfectly with my image of Gordon McLean, gentleman explorer. So I decided to record the places I would explore that summer, and tie it all together. The music is ‘Technodust’ by Colorpulse, used with permission.

Bushnell® Full-size Telescope (http://www.sears.ca/product/bushnell-full-size-telescope/06422070?ptag=1)
-or-
Celestron Astromaster 70AZ (http://www.canadiantire.ca/AST/browse/5/SportsRec/BinocularsTelescopes/Telescopes/PRD~0761098P/Celestron%252BAstromaster%252B70AZ.jsp?locale=en)

The Celestron: bigger aperture (70mm vs. 60mm), more solid tripod.

But both telescopes are basically toys. I wouldn’t recommend either. Too small aperture, terrible mounts, junky accessories.

There are only a very few telescopes worth considering in this price range — most of the others are toys.

Orion FunScope 76mm reflector @ $50:

Orion GoScope 80mm refractor @ $100:

Orion SkyScanner 100mm reflector @ $100:

Orion StarBlast 4.5-inch reflector @ $200:

http://www.telescope.com/control/product/~product_id=09814/~pcategory=telescopes/~category_id=dobsonians

What makes all of these scopes stand out is their smooth solid Dobsonian-style mounts, as distinct from the wobbly tripod mounts on the competition. In this price range, slight differences in price make for major differences in quality, so concentrate on items towards the bottom of the list.

For just slightly more money you can get a 6-inch reflector on a true Dobsonian mount.

Here are a few web pages with good information on beginner’s telescopes:

http://observers.org/beginner/j.r.f.beginner.html

For more advanced information, read Phil Harrington’s Star Ware, 4th edition (Wiley).

You’ll get the greatest value for your money with a Newtonian reflector on a Dobsonian mount, such as these:

Buy from a store which specializes in telescopes and astronomy, either locally or online; don’t buy from department stores, discount stores or eBay as mostly what they sell is junk. Find your local astronomy club and try out different telescopes at one of their star parties:

I strongly recommend that beginners steer clear of astrophotography until they have learned their way around the sky. Astrophotography is by far the most expensive and difficult area of amateur astronomy.

Many people who buy telescopes have no idea how to find interesting things to observe. A good introduction to finding things is NightWatch by Terence Dickinson (Firefly). A more advanced book is Star Watch by Phil Harrington (Wiley).

[Edit] Since you’re in Canada, before you do anything else, join the Royal Astronomical Society of Canada. We have centres in every province and most hold regular star parties where you can try out various telescopes. Some centres have loaner programs where you can borrow a scope for a couple of weeks to try it out. Don’t buy a scope from Crappy Tire or Sears: there are a number of fine real telescope stores all across Canada.

Ok i got a bushnell telescope today as a gift,No manual.I also don’t know the number thing for it (I know doesn’t help much,Sorry) But anyways when i look through the biggest lens thing i only see the reflection of my eye,the other lens…well i can kinda see stuff but its blurry,like looking through water an the other one,is just all black,i can’t see anything

Can anyone tell me what to do? I really don’t want to have to throw it away it seems really neat if i could only get it to work!

It seems to be in fine condition,Nothing scratched or broke an no missing parts.

You haven’t really given us enough information to figure out what’s wrong.

1. Is it a reflector or a refractor? A refractor has a large lens at one end (the objective) and a small eyepiece made of several small lenses at the other (eye) end. A reflector has an open tube with a concave mirror at the bottom of the tube and a small flat mirror at a 45° angle near the open top end, with the eyepiece on the side of the tube.

2. When you say you see a reflection of your eye, is it really your eye, or is it a large white circle with a small black circle in the middle, with three or four thin spokes joining the small black circle to the edge of the white circle? This is what you see in a reflector when it is way out of focus. Turn the focusing knob to make the big circle get smaller.

3. This is why I always recommend buying a telescope from a store that specializes in telescopes: they will help you get started. Failing that, try to find your local astronomy club and see if they can help you.

I have a Bushnell North Star "Go To" telescope. I got it yesterday. I assembled it and then took it outside to search the night’s sky. Although, I couldn’t see anything! Every time I align the red dot with the celestial object, for example, the moon, I look through the eyepiece(20mm) and see total darkness. It says something about looking through the main telescope tube in the instruction manual, although I don’t see why I would….I see nothing in it as well. The instruction booklet is very poorly written. I don’t see what I’m doing wrong here. I took the 20mm eyepiece out of it’s 2 plastic tubes and removed the protective thing off the main telescope tube. Am I missing something here?????
Oh, and earlier today (during day) I looked through my eyepiece when I had the red dot finder scope thing pointed at a tree, and I was able to see the tree clarified and zoomed in on my eyepiece like it’s supposed to be. However when I looked through it tonight, I got zip, nothing, nada.

Sounds as though the sighter scope is not correctly aligned with the main telescope.
The reason the instructions ask you to look through the main tube, is to confirm that the image you see in the sighter scope, is the same image in the main telescope.
Generally, the sighter scope has 3 small screws that you have to carefully adjust, so that it aligns with an objecgt correctly.
You have to repeat the adjusting exercise a few times (sighter, then telescope, then sighter, then telescope etc) a few times to get the alignment correct.

Secondly, lining up celestial objects is harder to do than lining up terrestrial ones such as a tree; this is because the margin for alignment error is greater in the former case, and will continue to be the case until you line up the sighter with the telescope correctly.

Repeat the exercise with the tree, tonight, and sweep toward a really bright object such as the moon or Venus (not sure of your location, so maybe the moon is your best shot)

Be patient, and enjoy
