IC 405 and IC 410: Flaming Star and Tadpoles

[gorann]

This was shot with a RASA8 and ASI 2600MC with the IDAS NBZ dualband filter (Ha+Oiii) under moon light. It is data that I collected two years ago and now processed using the latest starless processing tools (Star XTerminator in this case).

I do not think the objects need any closer presentation. The blue nebulosity in the Flaming Star is actually not Oiii but reflection nebulosity. However, the bandpass of the filter is broad enough to also pick up some of this. The starless processing allowed me to bring out also the fainter nebulosity that connect and surround these iconic nebulae. 142 x 2 min, so 4 h and 44 min. Stacked in PI and further processed in PS.

Cheers, Göran

If you mean there's enough to see at this focal length, I'm not sure.  I think the Flaming Star has some fascinating structure with the right data.  A modest SHO example @250mm and 3.8"PP shows amazing additional structure and I think some of this would be great to see at longer focal length (I'm certain I've seen examples on Astrobin).  I do miss the reflection element though and like an HaRGB version.

I've also seen some longer focal length images of IC410 recently that were stunning.  The tadpoles themselves bringing a new "wow" factor to that area.

With closer presentation I meant that I did not feel it was necessary to write an explanation about the nature of these objects and where they are found in the sky, with over 500 images of IC 410 just on Astrobin.

Yes, it is possible to go deeper and closer of course. I now added details on the exposure. So this was less than 5 hours on a moon-lit night. Would have been deeper without moon and more data.

PS. Here is a HaRGB close up of the Tadpoles I once processed from refractor data: https://www.astrobin.com/390129/C/
