Chameleon is a great camera for solar although the sensor is small. The USB 2.0 version seems now discontinued but it may still be found.

With my Lunt 50 I need to attach the camera to the T2 thread by means of a short C-T2 adapter to reach focus, don't know if needed with LS60 too.

Hi Mark, it's not rust they are bubbles in the glue between the elements, the external surfaces are perfect.

Thanks for your answers, I just wanted to explore a different solution than sending the item to Bresser, however I thinks that this is still the best thing to do.

After only one year of use my Lunt B1200 BF developed bubbles and other defects in the cement between the elements, they are visibile as superimposed on the solar images and are very annoying. I am very disappointed because I always treated the filter with great care and my other B600 which is four ...

Wonderful images, Eric, absolutely great. May you share some infos about your old Daystar filter ?

Great discs, Rainer, Sun is very busy in Halpha light.

Lovely images, Alexandra.

I too use a Chamaleon, what's the pattern suppressor you mentioned ?

Great solar discs, Pedro, a striking diffrence between SS and DS images.

A full aperture ERF is not needed but a good sub-aperture ERF is absolutely necessary. Forget UV/IR cut filters as they are not effective, a H-alpha filter of the type used for deep sky imaging is the minimum requirement to avoid long term degradation of the in-built BF. A 35nm Baader filter would w...

Sorry for being a pain. Would this work, can't find an exact 430nm. Andover Center Wavelength 430.7+0.4/-0.0 nm Bandwidth 2.0+0.5/-0.5 nm Transmission 45% Blocking 1x10-4 avg.

wow... no words!

wow... no words!

Thanks for your comments.

Franco, I never observed the Sun so often as during the pandemic, working at home has some advantages indeed...

A clear and sunny day over Milan allowed me to image our star in fair seeing conditions. How long has it been since the last time we have been able to see so much activity on the Sun ? I can't remember, it seems that centuries have passed since then :lol: But further activity is expected in the next...

Fine images indeed, Franco, your Combo works really fine.

Great images, Stu, excellent work.

Great images, Pedro, very detailed. A large spot is approaching from E limb.

Spotted this morning, a white facular streak and a double spot, just on the limb.

Great disc, very well processed

Great additions, Franco, well done!

Very good camera for solar imaging, particularly for full disc captures but nice for hires work too without the need for very slow f/ratios. I strongly suggest Firecapture for working with it, just start with the basic tools as described here https://www.youtube.com/watch?v=DJ1SpbCmM9U then graduall...

Superb images, Eric, full of tiny details and very well processed

Many details inside, last two images are the best.

Thanks again for your comments, that group is still spectacular.

Great images, very sharp indeed. The flare came out well.
