Al Ernst's Elephant's Trunk taken in hydrogen alpha

 After seeing Kah Wai Lin's recent image of IC 1396, Al says he was motivated to take a Hydrogen alpha image specifically of  the Elephants Trunk. The targeted area can be seen in the lower middle of Kah Wai's image.  This required stitching together an upper and lower frame, each consisting of one hour of five minute subs.

He used his C14; a .7 focal reducer and QSI583 with narrowband Ha filter.

I find it amazing what persistent people are doing in Bortle 5 and 6 New Jersey!
