NGC 2070 Ha

[Benklerk]

Been a while since a last posted. Weather and heat has been a problem for months.

NGC 2070 Hydrogen Alpha only

The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 160,000 light-years away, this is an extremely luminous non-stellar object. The nebula resides on the leading edge of the Large Magellanic Cloud. The Tarantula Nebula got its name because its glowing filaments of dust resemble the legs of a spider. It is a giant starburst region where the energy from the bright, hot young stars creates huge voids and filaments in the surrounding clouds of gas.

Very nice image, lots of details there in Ha, really sharp too...

Really bright! Nice!

It looks a little bit noisy. Have you calibrated the subs? I know this camera can produce cleaner results. Still a nice capture.

Yes I have Calibrated the subs from 100 darks, 100 flats and 100 bias.  But mind you, its only 11 subs.

Have you tried without the bias? It doesn't produce a good bias. Flat darks to calibrate the flats are recommended instead of bias.

 

Edit: Just thinking. Did you really shoot 100 x 10 minute darks?!!!

Great image, I'm on the cusp of buying a 6" or 8" RC and it's great to see what they're capable of especially the 6".

I did shoot 100 10min darks, took a few days. But I only do it twice a yr. I tried it without bias and it looked worse. I’ll shoot dark flats later on. But I really think the 1600mm on the 6” is to much for it. I noticed a lot of my images are soft compared to my 071 where they are sharp. I do use a auto focuser.
