Did some more Ha imaging with berts 300mm f2.8 lens, this time poking around the Gum nebula area. Went after very low surface brightness stuff.
The small bright nebula is RCW 32, that I imaged in colour here a while ago.

9 x 5 mins ISO 400 I was happy to get the fainter larger Ha emitting areas as well.
Before imaging that and while taking test images I noted a large area of faint nebulosity probably associated with the Gum Nebula or Vela SNR. Its VERY faint, note the image noise in bringing it up bright enough to see.
4 x 5 mins ISO 400
Its a real hassle finding stuff with the Ha filter as absolutely nothing can be seen through it visually, except the moon and jupiter. In the end I have to use the guide scope as a finder and take some short test images to verify target, and focus. No doubt Striker has the same fun with his Ha filter lol.
