LBN437 -  The Gecko Nebula in Lacerta
with NEXUS coma corrector
with 10" f/3.9 Astrograph @ f/2.9

Here is the "Gecko Nebula" LBN437 in Lacerta. Long exposures 
for the RGB data reveals a beautiful golden color for the Gecko, surrounded by 
abundant hydgrogen nebulosity.  It is quite faint, normally many hours are 
needed to record it well.  Here with the f/2.8 focal ratio provided by the 
Nexus coma corrector I was able to record it perfectly in only 10 hours.  
LBN442, the red hydrogen nebulosity is very large, occupying over 10 square 
degrees of sky making this target suitable for both close ups and telephoto equally.
