Advice on which camera to use with a Lunt 60/PT/B1200

Hello everyone,

I've had little experience with Solar imaging, and hoped I could be helped to select a good camera match.

I am not sure to pick something that images the whole disc, or do I select a chip that images a quarter or so of the sun? Mono is better right?

Aperture of the LS60 is 60mm, focal length is 500mm, F8.3.

Thanks for any advice,

Steve

go mono, for full disc get dmk51 or similar, for partial go the dmk618 mono or similar, going up the food chain means big $. i will be upgrading my dmk41 to a 51 so i can get the whole disk in one go. but adding a vixen 2.4 barlow allows closer detail when conditions allow. usb3 is the next level, but a bit out of my price range at the moment

The size of the full solar disk is approx. 1/100 the focal length.
This would mean an image size of 5mm.
To get a full disk image you're chip would have to be larger than this.
Smaller chips mean doing a mosaic.

Thanks Houghy, I'll have a look at these units to start off.

Cheers

Hello Ken,

Ok and thanks. I have to work out the FOV for each camera then.

I just wonder what other brands are reasonable, and what pixel size, etc? I'm not really sure what to look for in this kind of camera. I'll start looking at what people are using.

Thanks again,

Steve

What about these...

http://www.zwoptical.com/Eng/Cameras/ASI130MM/index.asp

http://www.zwoptical.com/Eng/Cameras/ASI120/index.asp

I see a few people have purchased these, any opinions?

They are economically priced, and there is a special on the 120MM at the moment with filters and a lens. It may be a good way to try/ enter this side of the hobby of imaging the Sun (and planets later on).

Thx,


Steve
