Hi All,

 

I planning to buy my first solar telescope for visual and imaging. I found on local market used Lunt 40mm B500 (few months old). Will it be a good option for beginning this new journey smile.gif?

 

P.S.

I've planetary camera ASI 585 MC which I would like to use with this Lunt.

 

 

Best Regards,

Kris

Yes, that's a good first scope for solar observing.

A colour camera is not optimal for solar, but you will get by with that in the beginning.
Later you can get a mono camera.

That’s a great scope to start out with and the tilt tune mechanism is simple to get the hang of. I would suggest getting the optional Feathertouch focuser which will make things much easier.

I have a PST which is similar to the Lunt40 (40mm, f/10, 5mm blocking filter, tilt tuning). Focusing and imaging on the Lunt should be easier, as the PST was not designed for imaging, and it has that pesky pentaprism inside a literal black box! 

 

Like Tapio said, using a color camera also is a bit of a handicap because you're using only 1 out of 4 pixels for the red Ha, but you can still get some decent images with it. Definitely you'll want a good mono camera for the sun in both WL and Ha, and it will come in handy for the moon as well!

Hi, thanks for Your comments. About the camera, following Your suggestions to go to mono, does it mean that ASI 290MM MINI will be better for beginning with solar imaging then 585MC?

Mono camera will provide better results.
Just a note that because of smaller sensor you just miss getting full sun in image.
To get full sun you need either camera with bigger sensor or use a focal reducer.
I've used a cheap 1.25" 0.5x reducer and it works fine.
