IC1396

[halli]

Hi

Took advantage of the unbelievable series of clear nights recently - at least three !- to try out narrowband for the first time.   IC1396 was one of the first emission targets to come into view early in the dark period from my location.  I took around 32 x 1000s light frames and about 16 x 600s each of R,G, and B using a 130pds and a 383l with Baader filters

The Ha version is shown below it has been stacked in DSS an had some initial processing in PI - just DBE applied and stretched

I am new to narrowband imaging and I thought I would simply  apply this to the RGB processed broadband image as a luminance.  

I wanted to take full advantage of the detail contained in the narrowband.  However there appears to be a number of ways of doing this ! eg apply directly to the red channel and also to use an algorithm created by a guy called Vincent Peris !  

Any advice for the processing from you experienced narrowbanders on the best way to combine Ha and RGB using PI would be greatly appreciated !

Nice image with good detail. Well done!

Very nice capture. Lots of detail showing.

Thanks for your comments guys

That's good!

How do you get DBE to work when the whole image comprises nebulosity? Do you follow a particular tutorial work flow?

Hi there.  Yes I must admit it is a tad counter intuitive to apply DBE to nebulosity when most of the time you are avoiding putting the DBE points any where near it!  

I thought I would apply it throughout the whole area of the image and see what happened !  It appeared to work ok as far as I could tell, although with narrowband I did not appear to have any nasty gradients to get rid of so the affect wasn't as dramatic as usual.

 I just used the conventional way of applying it apart from ensuring the DBE points were covering the complete image
