Everyone who has been attracted to a 6 inch telescope has their own reasons based upon their likes, dislikes, living location, weather conditions, discretionary money, etc., etc.
Back in 1978, the year I got married, I felt like I wanted to grow beyond the excellent Sears 76 mm refractor that I had purchased used earlier in the year. As I was tool savvy, coordinated and patient I felt like I had the ability to follow reasonable instructions, enough so to assemble a reasonable telescope where the most serious part of this "surgery" that I would be doing would be cutting a tube to the proper length and squaring up the ends. The various 6" refractor objectives with cells that Jaegers had to offer really appealed to me - but what to get? I approached the problem logically, drawing out the different focal length tube assemblies and then considering transportation and mounting issues. While the f/15 model would certainly have the "Wow Factor" and it's own special strengths, it would have to stay at home considering my vehicle (1976 Chevy Concours, basically a fancy Nova). Additionally a mount appropriate for an f/15 six inch scope would likely at that time, mean a heavy duty Cave mount. Quite expensive for a newly married 26 year old. Accordingly I settled on the f/5 as I did not want to compromise, it would have to be long f/ratio all the way or the ultimate wide field 6 inch (760 mm focal length). No regrets with this decision and with the shorter tube length there were no transportation issues and I could get away with the driven equatorial mount that Meade sold with their 6" reflectors. My 6 inch Jaegers is still with me and has undergone several modifications over the past 40 years. The tube has been shortened (a bit) twice. The original focuser is gone and replaced with an early AP focuser and I have a second (longer) dew shield on the scope. Internally it now has better aluminum baffles/glare stops via the use of Thousand Oaks solar filter cells.
On the sky it holds it's own. Back in 1978 I saw the Veil Nebula for the first time at a club event. It was the first time too for others there courtesy of my telescope. Comparing it to a friend's FSQ 106 and using both scopes at low power, the Jaegers did quite well, being able to reach deeper. No chromatic aberration issues noted at low magnifications when the view does not include a bright planet and 2nd magnitude or brighter stars in the field. Used for photography it does fairly well. To me bright stars with blue halos is not too much different from bright stars with diffraction spikes (reflectors). Additionally if you add a nebula filter (Lumicon Deep Sky) it does a great job in removing blue halos. So back in 1978 my Jaegers 6" f/5 satisfied my appetite. Today I have both a TOA 130 and a TMB SS130 which are both optically better than the 6" Jaegers, so there would be nothing to compel me to build one today, but for where I was then, what was available then, it was great!
