The only thing I know about solar imaging is to not to look at the sun with out the proper filters. So I took a picture with my canon Power Shot camera and processed it. I would like to know what the object next to the sun is? At first I thought it was a solar flare. But I don't know since its round. Can anyone please shed some light on this. I posted before and after images on my blog.

That is a lens flare.

Guess the next time I take the shot I need to be in the shade to avoid a lens flare.

Lol,

 

More seriously, 

I think it's an internal reflection of the sun - the sun's centre is below and to the right of the centre of the frame, and that flare is in the corresponding position above and to the left of the centre. 

 

If you positioned the sun exactly at the centre of the frame, you should find that the sun and its reflection would be lined up and the reflection wouldn't be visible. 

 

You sometimes get a similar effect when looking at a very bright star or planet through an eyepiece. It can help to get the star centred.

Wouldnt the camera be damaged without any filters? At least that's what I've read over here from the experts. I know you must've considered all the precautions but just be careful.

If cameras were at serious risk of damage, then any holiday snap that included the sun would have damaged the camera.

 

I wouldn't take a long exposure of the sun, and I wouldn't want to keep a mirrorless camera pointed towards the sun for anything other than a short period of time, but a snap should be safe,

It was a fast shot and I looked through the LCD not the viewfinder so I was thinking it would be okay. I plan on buying a filter for my 8 inch telescope and take some images with my NexImage 5 and see what I can see. Can anyone recommend any brand filters that would do the job and keep my kids and my eye sight safe?

A filter made from Baader Solar Safety Film is what would serve you best ... waytogo.gif
