Before & After Part#2

Finished up 2 of my "projects" NGC 2264 & the Leo Triplet. They can be seen below in chapter 2 of before & after:

M42 The Orion Nebula
 
The image on the left was taken with a Canon T3i, 5 exposures 2 minutes each on December 21,2011
The image on the right was taken with QHY9M CCD & Orion ED102CF refractor 10/21/2012,10/22/2012, 11/10/2012 & 11/18/2012
R-3x10min 1x20min
G-3x10min 4x20min
B-3x10min 4x20min

The image on the right won AstronomyForum.net's 4th Quarter DSO

 
NGC 2264 The Cone Nebula
 
The image on the left was taken December 2011 with an 8" Meade SCT LX-50 and a Canon T3i camera . (1 h 21 minutes of exposures in 21 sub frames)
The image on the right was taken March 4,2013 with a QHY9M CCD camera through an Orion ED102T CF refractor. (3 hours 10 minutes in 15 sub exposures) 
 
The Cone Nebula is probably one of the most dramatic before & afters. A modified camera is almost a must for this deep sky object.


M65,M66 and NGC 3628 The Leo Triplet

The image on the left was taken a Canon T3i (7x120 4x300 iso 400) & a Canon T3 (11x600 iso 400)
with a Meade 8" LX-50 SCT on March 18,2012
The image on the right was taken with a QHY9M CCD & an Orion ED102T CF
10x10  minutes Luminance
6x10 minutes Red
6x10 minutes Green
6x10 minutes Blue
3x20 minutes Hydrogen-Alpha.

The SCT telescope used on the left image has an aperature of 203mm. The ED102T is of course 102mm. Despite being 1/2 the aperature the triplet glass of the ED102T captures much more detail and has much sharper stars. Guiding with the 102 is also less demanding.
