  1. i would not bother with double stacking such a small telescope with a second etalon,  you are best to hold off and just save for a bigger scope.


    More aperture is more valuable than a double stack these days,  because the double stack filters just are not made to the same standards they were 8 years ago when everyone was super buzzed about the h-alpha scopes.


    Double stack filters are more or less, "rejected" filters that are always off band.

  2. very nice;    calcium processing is interesting.  Depending on exposure time and gamma settings you can capture three distinct; separate layers of the surface.

    I think its a bit different than offband tuning with h-alpha, because you dont actually have to detune your filter,  and  if you hit the right capture  setting you start seeing flux tubes and islands of spicules.



    Same filter,  vastly different appearance.     Entirely based on capture settings.    The entire surface has spicule islands on the right.   The left it just looks like granulation.

    Congrats! Nice to see world firsts over here on SGL.

    Do you think we are near the peak of what's possible for amateurs? Could e.g. better cameras in time do even more or are we already towards the limit?


    Right now there are new generation 3 sony sensors ready to be incorporated ;  they are super  speed with excess of 200 frames per second , with greater than 20megapixel high resolution .    Most computer owners could  not fit the bandwidth load of the data coming out that fast.

  4. If you hold the shift button on your keyboard; and press print screen button on your keyboard;   You can then open up a paint app and paste a screen shot from the clip board :)   (ctrl+V)

  5. So i have confirmed that I am the first amateur in the world to image flux tubes in calcium light.

    accurate pointers added to the first image,  this was not the first time I have captured these;  But it is the first time I have looked into this indepth.     








    here are my previous images recorded on November 5th 2020, this was  the first time i ever captured flux tube's, and I had no idea I was the first amateur to image these in calcium light.

    Captured with an explore scientific 127mm x 1200mm,  a skybender, and a meade #140 barlow operating at 3x using a basler aca1920-155um camera and a basler aca720-520 camera    Seeing conditions were obviously more favorable last year and I intend to look for these with a bigger scope.

  6. I have just confirmed that i have captured  Flux tubes, and I am the first amateur to record them on images with a calcium filter!





    The first time i ever imaged flux tube's was on November 5th 2020, without knowing  I was the first amateur to ever image these in calcium light.   The first  was  very high resolution , and this  example is very remarkable.
