  4. Can u upload a stacked image right out of APP or DSS. Not touchiing the saturation silder ? CS
  5. Added 3 hrs of Ha and O3 to the Sony DSLR image fully wide open at F2. My eyes cannot see the occilation nor the incoherence of the light signal. Cant say overall SNR s improved or aggravated the phase distortion by the filters . The colours look different and some of those dust lanes, star colours vanished and Nebula itself became more dense. Baader 7 nm and Baader F/2 High speed O3 filter were used. CS Rush DSLR image N band added.

  8. Hi, Roberto on Astrobin uses Fs 60 CB . You can take a look at his collection of Images with FS60. https://www.astrobin.com/360918/?nc=user well, I have used a couple of them too, Its quiet sharp and focus remains kind of steady even at temp fluctuations. Somtime back i wanted to dispose one of mine. Hope this is of help, CS Rush
  9. Adding one more Samyang image. ( 3 hrs with a Sony A7) CS Rush
  10. My Mantra is , No califrames, No Califrames, No Califrames. go away amp glow . Dont ask me why , this is humming in my head every time i start processing, may be cos Im lazy. ASI294MC PRO + Takumar 135 mm lens . HA /OXY injected to OSC. No Califrames Takumar 135 mm lens makes halos around bright stars.Stars r not round my laziness with guiding.(used previous night caliberation ) But was fun fiddling around with this OSC camera. CS Rush
  11. It s nice in green, and true what Wim wrote too, but its ur choice i guess. Bcos NGC 4631 from Scott Anttila is Greenish like yours. APOD nasa 2004 is greyish looks Natural. Have a look. Exist also many bluish versions. https://apod.nasa.gov/apod/ap020329.html You have enough data there so you can go either way:) Run backgraound neutralisation bvor streching. worst case 50% SCNR. We quit now, Green help for Colli help.:) CS Rush
  12. This looks almost like a clean dark frame. My work horse CCD cams shower blizzard snowfstorm appearance through the wind shield.? Especcially with Baader Ha filters. A cosmetic correction or a Bad pixel Map (like Dave wrote) will remove this. In my experience worst noisy Chips like KAF 8300 still make pretty images. I agree with Ollys point do not judge cameras from the noise. Processing noiseless cameras are not so easy. True. CS Rush

    Is it ok if i ask ,did you add the RGB lum to the Master Lum ? or mixed it 0.20*+ 0.80*using Pixel Math. MT (PI) dark ring star residuals (unless the star mask is above optimum) in a drastic crop will not Pardon the Galaxy:) Its a super splendid image. Rush

    M82 HaLRGB

    Rodd its a spledid colourful galaxy. Nicely done. Very interesting super lum Approach. Delicate question ? perhaps reduce the star size bvor cropping. Kind of blocky star background for a razor sharp Galaxy or not ? Super Image, CS Rush
