Can I use x-ray film with my etx-80 and canon 1000d to photograph sun

[brantuk]

Nope - you need Baader Solar film - this is the safest way -

Never look at the sun in a telescope or binoculars without proper filters - HTH

No, very few solar x-rays reach the ground, 1 or 2 counts per second. Most of the x-rays around us are from rocks and gases like radon etc. Also, glass doesn't focus or refract x-rays so it wouldn't form an image anyway in a normal telescope

You get more solar x-rays as you go higher in the atmosphere but even then it's only a few 10's of counts per second.

X-ray imaging is pretty specialised.

well i use a x-ray film sometimes for solar photography with my canon 1000d with a 55-250mm lens @ 250mm

i have taken this image with an x-ray film rest of details are on pic itself http://postimage.org/image/9jinbt1rj/

bit confused ...Why ask if you CAN if you already HAVE??...I think without the correct solar filters you are risking serious eye and/or equipment damage

[brantuk]

Hmmm.... I have to agree with Pallas - you're taking a big risk. Far as I know you need special filters for looking at the sun and/or imaging it. Baader film will give you white light views (mostly sun spots) - other than that you'd need a special solar scope - you can also get special glass filters and etalons for modding doner scopes.

If you have to ask the question about x-ray film then I think you probably need to research this more thoroughly to get a better understanding and make yourself fully aware of the dangers involved.

no what i meant was use this with a scope at high magnification's and btw i always use live view

Hi

This is not an x-ray image, it's a visible light image. X-ray film is just photographic film so you have captured normal visible light. Glass does not refract or focus x-rays, you cannot form an x-ray image this way.

To recap, I think the poster was asking about white light imaging rather than visual. Almost any front mounted filter with enough attenuation should be safe enough for a CAMERA but only proper solar filters are safe for the EYE.

I agree. For imaging i think x-ray film (where do you even get that?) should be fine for sticking infront of your DSLR. For observing the Sun................FORGET IT.

Peter's knowledge is far superior to mine on this - I was just worried in case you might be tempted to look in the eyepiece - you can be sure his advice is sound

Thanks for clarifying Peter

I don't think the OP was trying to make an X Ray image.

I presume he has been using X ray film as a makeshift white light solar filter to use with his digital camera and 250mm lens and presumably wants to know if that will work when his Canon is hooked up to the ETX-80.

I think this is totally inadequte and he should invest in some proper solar filter film as brantuk suggested. Alternatively a glass filter.

I have a Astro Engineering glass filter which screws onto my ETX-70 and gives excellent results.

Do you mean a glass filter for observing or imaging?

Please say for imaging.

But x-ray film is just normal photographic film, it gets exposed when an x-ray photon hits it, this is the principle of all film x-ray photography. It wouldn't work as a Solar filter at all and would be totally inadequate and dangerous.

I think the OP had placed x-ray film (i.e. normal photographic film) inside a camera and taken a picture, it worked because its normal film and has taken a normal white light image, it's not produced an x-ray image even though it's x-ray "film".

Maybe I misunderstood the original quote??

Just been reading and the 1000d camera is obviously digital, so it can't take film, please ignore my previous comments as I obviously misunderstood. The OP must be using x-ray film as a filter??

Thanks

The camera is a Canon 1000D (digital) so the OP is trying to use an exposed piece of film as a solar filter. It might work but, on the other hand, it probably could be dangerous if used visually or could damahe the camera if there are any scratches in the film to let unfiltered light through. It's not worth risking.
