Benklerk Posted April 8, 2019 Share Posted April 8, 2019 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.

david_taurus83 Posted April 8, 2019 Share Posted April 8, 2019 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. Link to comment Share on other sites More sharing options...

david_taurus83 Posted April 8, 2019 Share Posted April 8, 2019 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?!!! Link to comment Share on other sites More sharing options...
sulaco Posted April 8, 2019 Share Posted April 8, 2019 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". Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
