Last night I used the TEC-140 to record an entire night IC1805 (Heart nebula). I imaged from about 12 midnight to 6 in the morning while I was sleeping. Results was 11 images of 30 minutes in OIII. I combined these with my earlier H-alpha images. Then I created a synthetic green channel from the H-alpha (red) and OIII (blue). Then selective colors were used to change the color palet to a Hubble like palet. I like this combination a lot because it keeps stars natural colored and gives a nice color balance.
