Hi All...

I pillaged the image archive on the weekend and pulled together a few examples of CaK images I've taken over the past 10 years. As requested, no pics of the hardware, but the evolution of the imaging systems used is listed below:

2008 - 2010 - Lunt 60mm/B1200CaK scope or a Williams Optic 72mm, f6/B1200CaK (the B1200CaK module was interchanged between the two OTA's
2010 - 2012 - Lunt B1200CaK + Celestron C102 OTA
2012 - 2016 - Lunt B1800CaK + IStar 150mm, f8 OTA or CR-150, f8 OTA
2016 - Present - Lunt B1800CaK/Solar Wedge Hybrid/Baader CaK filter + IStar 150mm, f8 OTA

Cameras used are primarily PGR Grasshopper Xpress (ICX674 chip), ZWO 175MM, and ZWO 1600mm.

The early years...2009-2013:

The days of solar maximum certainly made a CaK filter a joy to use ;)

If there are any questions just let me know.

Nice. Makes me look forward to the next maximum, assuming we have one. George

oh we will have one for sure have solar max again in 2028, and the imaging sensors by then will be well over gigapixel resolution at the size of a bearing in a ball point pen.

Unfortunately, inflation will remove all ability for anybody to afford hobbies and exhaust pollution from all car's will render the telescope community useless. You more than likely will be stuck in a computer simulator watching iris laser projection documentaries of an antiquated notion called "sunlight". :lol:

with absolute seriousness though, all the air/street traffic by that time will just kill the sky. Maybe we will have drone telescopes by then that can just indefinitely hover above the smog.

Televised sunrise anybody?

It is too bad that some places on earth suffer from the pollution as shown in the pic posted for the 'televised sunrise'. I suspect that unless there is major change in thinking these places will continue to degrade. I only hope that clearer minds will continue to push efforts to preserve the environment for generations that have not been born yet.
