M20 - Trifid Nebula
Image of M20 taken with 8" SCT with 6.3 focal reducer.
Autoguided using PHD and an 80mm achro + webcam. I used a 2" IDAS-LPS filter to reduce light pollution.
17 x 3min subs with an unmodified Canon 350d @ ISO800, taken from my suburban Perth location. Image stacked in DSS and post processing in PS.
This is my first image this year of M20.
(Having just completed my dew heaters I am pretty happy that I can now get dew free images.)
Any comments or suggestions greatly appreciated.
