Question

hi i got the telescope from tejraj and co in mumbai. those guys are supposed to be the best in india but even after following the exact instructions in the manual(which is woefully very technically written) all i can see is a black space with a sort of cross hair even broad daylight !what am i doing wrong?

Answer 1

Hi. This is what you get with a Model D 100mm Startracker telescope package:
The Model D = 100mm / F = 1000mm STARTRACKER 80STARTRACKER 80 ASTRONOMICAL TELESCOPE (40x to 250x)
includes the following Standard Equipment and is a complete working telescope for visual observation.
A) D = 100mm / F = 1000mm STARTRACKER 80 Optical Tube Assembly.
B) RACK & PINION FOCUSER 1.25" OD with dust cover.
C) THREE EYEPIECES (1.25" OD BARREL DIAMETER) 25mm (40x), 16mm (62.5x) and 12mm (83.3 x).
D) VARIABLE BARLOW (1.25" OD BARREL DIAMETER) (1.5x = 2x = 2.5x = 3x), 60x to 250x Magnification.
E) 4x BARLOW LENS (1.25" OD BARREL DIAMETER) 160x, 250x and 333.2x Magnification.
F) 7x25 STARFINDER TELESCOPE.
G) DUST COVERS One for the front opening and one for the rear end.
H) UNIVERSAL METAL MOUNT holds the Tube Assembly.
I) METAL TRIPOD or PIER STAND with AZIMUTH ADAPTOR.
J) STARTRACKER SYSTEM OPERATING MANUAL.

If you got all that, then you have a great set-up. The 7x25 is a small telescope that mounts on the large telescope. Some space objects are too small to find with the large telescope. So, the small one is mounted on the big one. Find a star with the small scope and then look at it with the large scope.

When you look through the small scope, you should easily see stars. If you see only blackness, then there is probably a lens cap over the end, or a lens has been misaligned during shipping. Discover what is blocking your view and fix it.

1. Make sure you can see something with the small scope as a first step in using the large scope. When you can see something with the small one, go to step 2. Probably do this during the daytime, and try to see a distant mountain top. Then you can work on the set up easily.
2. Once the small scope is looking at something, and the cross hairs are aiming right at it, use one of the eye-pieces to look at the star with the big scope. You have three eyepieces. :
[ THREE EYEPIECES (1.25" OD BARREL DIAMETER) 25mm (40x), 16mm (62.5x) and 12mm (83.3 x). ]
These magnify the image of the star. They fit into the rack and pinion focusing mount. Start with the 25mm eyepiece. Compare the location of the target with the target's location in the small scope. There are some adjusting screws that let you match what you see in the little scope with the big scope. If they are not in alignment, then when you use the more powerful eyepieces to look at a star, the star will not be visible, since it will be off to one side or the other. You must align the scopes before they will work together well. You must align them while looking at some object that is as far away as possible! Make fine adjusments as needed during actual viewing.
If you can get it aligned on a star in both scopes, go to the next step.
3. to view more distant objects, you need to align the tripod to actual North, not magnetic North, and your latitude if you have that kind of mount. Then as the Earth turns, you can continue to look at something by turning one wheel on the telescope mount. If the mount is not alligned with true North then you will have to turn two wheels to track stars. If you have a motorized clock driven mount, you must align the mount to both North and Latitude.

In order to take pictures you will need an adapter and a camera. If you want to take long exposures (over 15 seconds) then get a motorized clock driven mount. That is how they get those beautiful nebula.

;-D Wow I wish I had a scope like that. Wow I wish I could see stars in the sky through all the nighlty cloud cover. :-(

Answer 2

well if you are seeing crosshairs, it sounds like you are looking in the finder scope which isnt the actual telescope, that just helps you find things. You need to find where the eyepiece is located on your telescope and look through that.
