Newton rings are present...

The image of our Sun, was captured using .SER video format, four thousand frames in Hydrogen Alpha light; using a Daystar Quark Chromosphere filter, UV/IR filter and ZWO ASI174mm monochrome camera. The optical instrument used was an Explore Scientific FirstLight 127mm Doublet refractor telescope. To the upper right, you will notice a ring-like pattern, known as Newton rings. The optical system assembly will require a camera tilt adapter or Daystar Interference Eliminator, to remediate the Newton rings.

Well, until the Daystar Interference Eliminator gets here, this ZWO Tilter should do the trick in removing those nasty Newton rings, from my solar images.

Tracking is slightly off, guess it's back to the guide scope for longer exposures.

Figured I would try processing the North American Nebula, NGC 7000 (Cygnus Wall), in color using the Chroma 2" luminance filter and the Radian Triad Quad band 2" filter, also as a luminance filter, with the stars added. The ZWO Red 2" filter was not my first choice, but it was the only red filter. I am Hoping to soon replace the remaining ZWO RGB filters with Chroma.

The North America Nebula is an emission nebula made up of dense dark regions of interstellar dust, that lies approximately 1600 light years from Earth. The image was taken using a Chroma Luminance 2" filter and Triad Quad Band filter.

Decided to purchase an Explore Scientific FirstLight 127mm doublet achromatic refractor to use as a solar telescope for detailed chromosphere solar photography. There is a Daystar Quark Chromosphere and ASI174mm monochrome camera attached. The Explore Scientific 50mm finder scope (with solar mylar protection) could cause small errors in balancing and tracking. I may end up using the cheap red dot finder, with Solar mylar securely wrapped on the front. Daystar documentation states the Quarks works best using refractors of F/4 - F/8. The ES FirstLight doublet refractor has a focal ratio of, F/9.4 and with the Daystar Quarks 4.2x telecentric internal Barlow, which should push the focal ratio to F/39 give or take. Hopefully, this will work out to image capture great chromosphere surface details. I do have a 2.5x Televue Powermate to evaluate as well. Hopefully, this weekend I'll test out if the skies finally clear.

Five SDR channel, KrakenSDR with built in coherent tech!

What a beauty, I can't wait to receive this powerful five channel SDR receiver! 🤩

I'm excited, ordered the KrakenSDR, five channel software defined radio receiver for my two, 3-meter radio astronomy telescopes last October 2021. Finally a shipping date, end of this month, May 2022. I tell you, supply chain issues hurt! This little jem will allow me to combine both RAS telescopes into an interferometer, with coherent fringes.
