Hello,

 

Is it possible to observe the sun using some sort of filter? I do not own a fancy telescope but I would like to "unlock" all of its possibilities and I've always find solar observation to be fascinating.  

 

Thank you,

 

Zeus

Yes, there are filters that work for that. They go over the objective on the front end of the scope. Meade has had a policy of not promoting filters that attach to a regular scope. If one happens to come off while you are viewing, wherever The Sun's image on your retina will be a permanently burned hole. You will be blind in that spot.

Hope this helps,

Thank you Bill,

 

In such case I'll rethink this option.

Most people use baader solar film which does work well.But you have to take precautions to make sure everything is secure on the main scope and finder scope.One boo boo and you have no eyes left.Many people have used the baader film with great success.

I'm probably not going to, the chance of loosing my vision is not one I'm going to take.

 

Perhaps one day I can afford a coronado.

There are many safe solar filters out there for a given telescope diameter, and are safe if used properly.

 

You must always remember to keep your finder scope covered (or get a filter for it too).

 

To locate sun with a proper solar filter, and no finder scope, simply point the scope in the general direction of the sun, and then watch the shadow of the scope on the ground in back of you. use the hand paddle to move the scope until the shadow of the scope becomes a circle -- then you should be right on it.

Thank you, I'm still thinking what to do what I think I wont do it.

Absolutely YES! I use binoculars to make drawings and image directly using a filter and telescope.

 

Oh, yes and I also have a Coronado:

I have not tried binoculars for solar viewing.  I will have to get set up and do that some time.

Having 15x70 bins is a great help but 12x50s should show a few sunspots.

I have a pair of 15X70 on a parallelogram mount, including a zero gravity chair.  Using it currently for the Astronomical League's Binocular Deeps Sky Program.  Sounds like that should work well for solar, with the appropriate filters on the objectives.

Yo tengo un telescopio Infinity 70/700, me regalaron un filtro solar Mylar y déjeme decirle que la observación solar es muy satisfactoria, las manchas solares se ven muy bien, normalmente uso el ocular de 26mm (me dá 27 aumentos) y hasta he tomado fotos.

 

El filtro solar me lo dieron para poder hacer observación del eclipse parcial de Sol del 21 de Agosto de 2017.

 

Espero que esta información sea de ayuda. Saludos.

Here is a direct computer translation of Abraham's post:

 

I have an infinity 70/700 telescope, I got a Mylar solar filter and let me tell you that the solar observation is very satisfactory, the sunspots look great, I usually use the eyepiece 26mm (gives me 27 magnifications) and I even took pictures.

 

The solar filter gave it to me to be able to observe the partial sun eclipse of August 21, 2017.

 

I hope this information is helpful. Best regards.

 

Thank you Abraham!  That is good information.  I have used one of the older NG 70 refractors a lot.  I found that size and focal length to be a very good combination.

 

Best Regards,

Having a wife who is a native Spanish speaker helps but I managed it without her help.
