Question about Optics

1 Answer

Hi! For Christmas (2010) I received a skywatcher telescope SK1141 EQ1 (D=114mm F=1000mm). I would like to be able to view the solar eclipse which is due to take place on the 3rd/4th January. I was wondering if it is possible to back project from this telescope and if so how should I go about it? If not, do I need to purchase a solar filter and how much will this cost? I would appreciate it if you get back to me asap. Thanks for you time.

Theoretically you can use eyepiece projection for solar images, by placing a screen opposite the eyepiece and focusing on it. Some telescopes come with an accessory attachment for this. However, there is the possibility that the eyepiece will be damaged by the heat, especially if it is one with cemented elements or if it has plastic parts.

Do NOT buy or attempt to use a solar filter to look at the Sun. If the filter cracks from the heat you will instantly lose your sight.

I'm not sure that I would bother with a telescope during an eclipse. You may not even be able to get it lined up and focussed in the short time available. At the last eclipse, I made a pinhole camera with a pinhole in a piece of foil placed in a blacked out window in a darkened room. The image on the hand held paper screen was good enough to photograph.

How can I use my telescope to safely view the solar eclipse?


Yes, you can, but with qualifications. You are evidently aware that you must never view the sun through the eyepiece of a scope without proper protective attachments being used. Blindness in that eye will be instant. Solar eclipse spectacles will not be sufficient protection as the light is focused powerfully at the eyepiece.

You can safely use a glass solar filter which attaches to the front of the scope. Tape it on for extra safety.

You can attach a piece of solar-protective film to the front aperture of the scope. Do so securely.

You should not ever use a solar viewing filter which attaches to the end of the eyepiece. There were a lot of these around until governments began banning them. The danger is that the concentrated heat of the solar image at that point will crack the filter, leaving your eye unprotected in an instant.

Can I use this telescope to view the solar eclipse and if so, how do I do this safely?


Only if you have a white light filter. You can make one or you can buy one, I have done both.
Here are a couple of helpful links. The first one explains white light filters.

This link is a place that sells the material.

Where to find them in sri lanka?


First I would not buy that very small 60mm telescope. You would be better off buying a pair of 10x 50mm binoculars and a good star chart.

Check out the Skywatcher brand of telescopes which are manufactured in Europe--

You stick it into the focuser and tighten the small thumb screw. Then you put your eyepiece into the diagonal.

BUT! why would you do this? You only use this for terrestrial viewing not for night time Astronomy.

I am having problems viewing


All astronomical telescopes show upside down images. There is no up or down in space. To ERECT the image would take additional GLASS lenses. MORE glass means less light pass-through for those dim sky objects.

This is a simple refractor telescope. They all assemble in the exact same way. Meade has a similar telescope and maintains a page with all of their manuals. Here:

How to take still photographs of solar eclipse


DO NOT look directly at a solar eclipse... You will do permanent damage to your eyes. If your camera has a "live view" LCD screen (Where you can look at the LCD while composing the image), use it to view the eclipse. DO NOT look at the eclipse through an SLR lens or other OPTICAL viewfinder unless you have the proper equipment in place to protect your eyes. You will typically want to use your full optical zoom on the camera to make the image and set the ISO setting to its' LOWEST possible setting. You will have TONS of light, so a low setting will reduce noise, giving you a much higher quality image. If you have exposure compensation on your camera, set it to underexpose by at least two full stops. Since the scene is so bright, it will fool a light meter, thus the need for this compensation. Also remember to use a tripod as well. When you use telephoto lenses, it magnifies shake introduced when you hand-hold a camera. If you're using an SLR camera, you will need a filter to view the eclipse through... here is a site that will give you GREAT detail on safely viewing a solar eclipse:
http://www.mreclipse.com/Special/filters.html

If you want to purchase one for your lens, go to any astronomy equipment sales site or telescope manufacturer. Hope this helps and good luck with the eclipse!

Lesser viewing area in my telescope


All telescopes have small fields of view-- even what is called a "rich field scope" has only about 2 degrees of view. Most scopes only have about 1 degree of view.

The key component is a short tube and a fast mirror of F4.5 or faster.
