Sadr Region BiColor Narrowband


Recommended Posts

I finally got some SII Data to add to my HA data and got them processed.  5 hours 20 mins of data.   So here is my version.  Mapped the HA to green and the SII to Red and used the HA as a LUM.  I like the definition between the green and gold dust so i left the colors instead of changing to the HA gold like the modified Hubble.  Thoughts?

I am going to add OIII and see what that brings.  Had a tough time with colors I think I had 5 different color combos I was playing with.

I've never imaged using full NB, I have a 7nm HA filter, but I'm imaging with a dslr so it's not ideal. I can imagine with all the options available it must be tough choosing a combo that you like. When you get the OIII will you remap all the colours or just add the data to a different Chanel ?

I started out with a dslr but never had a chance to try a HA filter with it.  The only thing I did was self mod my t3i.

 I'll probably remap and play again to see which brings out the most detail for the colora shown.

I like all the options that are available with NB, my next investment will be a CCD I think, if PI doesn't tip me over later. I'm on the 14th floor in the middle of a city with only a west facing view. The reason for the 7nm was so that I can image off the balcony, the IDAS light pollution filter just didn't cut it in the middle of the city lol. But it's great when I go to my usual observation site. 

I'll keep my fingers crossed and hope you get decent weather for your OIII data. And I'll look forward to seeing how this image evolves.

Like the images you are producing. The detail in them is fantastic. The colour schemes you are using add a surreal feel to the images which is great.

How are you getting good focus on the HA filters. I am just starting out and have just got an Astronomik 12nm Clip filter. Do you focus fist without the filter and then clip the filter in place. Any advice would be greatly appreciated.

I am so sorry about this delayed response.  I have been out of the game for a bit here.  

I use a filter wheel and focus with each filter using an autofocuser.  It pinpoints the best number for the stars in the image and sets it for me every hour.

      This is currently a work in progress. Playing around with Photoshop CC to try and extract more detail from this image. This image is not as cropped as the others I have posted.

      I grabbed 3h40m of the Sadr region stretching from the crescent up to NGC6914 (not visible as it's a reflection neb!), in HA light - may add to this in HA, but also would be nice to bring LRGB into it at a later date. 
      QHY163M, Canon 200mm 2.8L II (working at f3.85), Losmandy GM8 - taken 17th Sept 2018, West Oxfordshire. All in 5min subs, guided with a ASI120MM on a 50mm guider. Baader 7nm filter. Processed in PI.
      Thanks for looking.
