      Glad to hear that you are pleased with your TMB.  I bought a 152 in 2003 to view Mars...I still enjoy using it and get a special feeling when using it.  Also, I have a MS-11 with the CF tube. 
      I live in Northern IL and the seeing is never all that good.  On planets the TMB always offers better views of them than does the 11" SCT...and yes, it is well collimated.  I have also found that on many nights stopping down the 152 to 127mm will offer slightly better views on the planets...I did ask Thomas Back about this...he confirmed that he would often use a smaller aperture APO for the same reason.

      After what seemed like a small eternity finally had a chance to get the TMB out - Skies weren't great but at least no clouds or rain -

      Mounted on a CGEM - My first view was Vega - Unbelievable - absolutely no color dead pinprick of light - My views that evening included some clusters (M4 - M13 etc) Planetaries(M52 -M27) and so on. I used a variety of eyepieces which included Radians, orthos, Burgess TMBs, old Research Grade 20mm and 15.5mm Erfles - Series 4000 and 5000 Meade SWAs - Pretty much the whole gamut.

      In every case I was totally enthralled with the views. Again, stars were absolute pinpricks of light, no fringing, no spikes, just points.
      The diffraction pattern was "perfect" -

      I waited for Jupiter to clear the trees and that's when I knew I had the right scope. I had never seen detail like that before. The colors were as the photo's. Detail within the belts was obvious.

      I have been doing this for over 54 years. Had a lot scopes - Currently I have the TMB, a C11 (carbon fiber tube, crayford) 8" LX90, 1970's vintage C8 and C5 - Meade AR5 -

      My scope of choice The TMB 130SS - My skies (as with probably most of us) are horribly light polluted. This scope seems to cut through that better than any of the other scopes - The images this instrument displays are as good as it gets - I cannot imagine a more "perfect" set of optics.

      The interferometer pictures of this lens are astounding - Dead parallel lines -

      I know there is no Nirvana when it comes to scopes but this is as close as I have ever seen. I look back of the scopes that are gone that were once "keepers", this one will be with me until I'm gone -

      If I were to look at a downside it would be of course aperture. It cannot resolve M13 like the C11 however the C11 does not have the purity of image on Jupiter - Which to I consider the most important - Both, that's why I have both - All the other socpes will go except my pets, the C8 and C5. There is a story behind these that has nothing to do with an evaluation.

      Rest assure fellow TMB'rs these are great scopes and hold 2nd place to no one.
