Now that we're getting out of solar minimum, my interest in solar observing is returning significantly. While I've had several solar-capable scopes over the years -- I have a Lunt 35, and 8" and 5" white light filters -- I've never been able to keep up a systematic observing program because in Houston, it gets a little warm outside during the daytime.
My Lunt is wonderful. It's a dedicated solar scope and it is grab and go for even just a 5 minute session in the middle of the summer. I want to do the same for white light. I want to minimize thermal effects, so I'm thinking refractor. I'm even thinking of one of those relatively inexpensive 70mm f/10 achromats on an "okay" alt-az mount. (I'm aiming for 50-60x magnification and dedicated to white light solar.)
I've never used a white light solar filter on an achromat before. Is chromatic aberration even a factor on such a scope with a white light filter?
