As one of the last three people in the world still imaging with an unmodded canon 300D
, I wanted to experiment with an OIII filter (instead of a H alpha filter) to see if one could still enter the realm of narrow band imaging with an un modded Canon
Would appreciate any comments on this first foray.
The target was the lagoon nebula , and this represents 50 minutes of exposure-five 10 minute subs, stacked and processed in IRIS. Scope was ED 80 (autoguided), camera the Canon 300d, Astronomik OIII filter. Imaged last Saturday, but I only got around to processing tonight.
as an independent exercise I will see what happens when I add this data to RGB images -also with an un- modded Canon-from last year..when I get around to it
