  1. Transparency on the evening of 30th November was fantastic but seeing was very sketchy.

    I did three captures that night and processed the first two as the best 20% of 2000 frames. These have proved to be marginal at best.

    I tried this one at 10% and the detail is better. Not great but I like the way the setting sun has picked out the western face of the Montes Alpes.

    Celestron C6 SCT- HEQ5PRO, ZWO ASI 290MC. 

    Stacked in Autostakkert3! with levels, exposure and saturation adjusted in GIMP.

  2. Welcome aboard @FlaviusYNP

    Beautiful images. I do really like the landscape/ skyscape images.

    I guess I don't have to tell you how lucky you are to live where you do. We spent a few days in Yellowstone a couple of years ago, just before the park closed for the winter. One of the worlds spectacular settings.

    There's a whole universe of ideas here!

    I'd design the system with my planet in the Red Dwar's L2, I know, I know not stable enough, but this is artistic licence.. 😁

    So the Red Dwarf would be permanently superimposed on the primary star. It would make for some interesting imagery.

    I wouldn't want the planet's rotation tidaly locked either. No, a habitable planet with sun(star)rise and set. And butterflies, any alien world worth inhabiting would need butterflies.

     

    Paul,

    I will quite happily go with your planet design proposal as long as Slartibartfast subs to do the fjords.

  4. More product from my session a few nights ago.

    RVO Horizon ED72, Sony a6300 set at ISO3200. LP filter.

    30 x 30sec lights, 30 x 1.6s flats, 10 x 10sec darks.

    Stacked in DSS, histogram stretch in Siril and levels etc. tweaked in Gimp.

    Far from perfect but I am happy to reveal the nebulosity for the first time.

    I have no idea what has caused the darker ellipse near the centre of the image...

  5. M33 through the RVO Horizon 72ED and Sony a6300 set at ISO3200.
    30 x 30s subs with flats, darks and bias. 
    This time I used Siril for the full stacking process plus histogram stretch etc so it demanded Biases.
    Levels tweaked in Gimp.
    As I learn the art of processing I hope to be able to improve the look of the images and lose some of the grainy effect.

  6. Here is an improved M31 capture on the new 72ED. This time via the Sony a6300.
    30 x 30s subs with flats, darks and bias. Still not got the hang of things like darks and bias as I can still see noise and glow.
    I also found that I need to expose darks, flats and bias frames before parking the scope as the Sony auto corrects frame orientation so, on a couple of other targets, the frames flipped from landscape to portrait.....

    No, it only means that if an archaeological site is not buried by later deposits, and instead stays on the surface and is exposed to the elements, most likely it gets completely eroded away and disappears.

    But the later deposits- where do they come from?

    I expect some is from redistrbution of material by the elem,ents but, more material arrives on earth from space every day surely?
