Good morning, I would like to consult you the following subject: I would like to start in the solar observation H alpha, and I am not very clear which telescope I can be better, if the PST 40 or the Lunt 50 B600, I would use it for visual observation. I currently do not have a refractor telescope, so I do not wanna ask for the Daystar chromosphere model. Is there a difference between the two models? Any clear advantage over each other? Nor do I consider the higher models, such as the Lunt 60 B600 or the Coronado Maxscope..60, I do not know very well whether at the visual level would be a clear advantage over the above mentioned, but in money! Thank you very much for your opinions. Best regards Paul
