The Rosette Nebula’s image was taken using a single shot dedicated color astronomy camera, ASI2600mc Pro; exposure time was a little more than two hours. The camera temperature was a chilling -25 Celsius. The filter used was a Radian Triad Ultra Quad band filter and the optical instrument used was an Explore Scientific 165mm APO air-spaced triplet refractor.

Unfortunately, the clouds rolled in and limited the amount of exposure time data gathered, until next time.

The sun's chromosphere captured using a Daystar Quark Chromosphere Calcium H-Line filter and Baader Calcuim K-Line filter, combined and processed.

The Ring Nebula is the left over of a Sol-type star also designated Messier 57. In the center of M57 is a dot, the remains of one sun-like star, but all that remains is a hot stellar core, known as a white dwarf. The Ring Nebula is located approximately two thousand light-years from Earth and is in the constellation Lyra. The optical system used was a TPO 304mm Ritchey Chretien astrograph, and ASI2600mm Pro monochrome camera at a temperature of -16 Celsius. The filters used was LRGB & Hydrogen Alpha, with an exposure time of 6-hours.

Finally received the RSPdx SDRplay, multi-channel SDR receiver.Hopefully the Coherent Receiver, 4-channel SDR multi-channel receiver, order will come through as well. The 4-channel SDR receive is needed for the additional, 1–8-meter mesh satellite dish antenna; arriving in July, 2022. Now it’s time to work on the radio interferometer system configurations.

Earth's Natural Satellite was captured using a 165mm APO Airspaced Triplet refractor, and a ASI2600mc Pro, one-shot color (OSC), dedicated astronomy camera.

Received word today, that the KrakenSDR lead time has been extended to 126 more days! Well, I originally placed the order through Crowd Source Funding (mentioned many times) October 21, 2021, and have been waiting patiently. After waiting for May 31, 2022, the new delivery date, which has come and gone. The latest date for shipping was pushed to June 17, 2022, and again pushed to June 24, 2022. So, I requested a no-nonsense expected delivery date and found out the lead time is now a 126 days, as mentioned! My dilemma, do I keep waiting or just let the time pass and not think about it? Fortunately, all is not at a lost. There are other products out there like the RSPdx SDRplay duo SDR receivers or products from Coherent Receiver, which makes SDR dongles stacked for all types of projects; including radio astronomy (RAS) and interferometers. You can even purchase Antenna Switches and Noise Generators, from Coherent Receiver's product line of SDRs. I've already ordered the RSPdx SDRplay's SDR receiver and as backup, ordering a quantity of two, four-stacked SDR dongles from Coherent Receiver, with all having expected delivery times this month! Far more efficient delivery timelines than the KrakenSDR's nebulous delivery date(s). My radio astronomy interferometer project has been held up far too long. I wish to be patient but a year delivery time is ridiculous, in my humble opinion. Most of my other RAS associates have cancelled their KrakenSDR orders! https://www.astrobin.com/jgglym/?nc=collection&nce=9484

Solar work still in progress... ugh..

The Sun’s chromosphere captured, along with a group of sunspots on 05/30/2022 using a Daystar Quark Chromosphere hydrogen alpha filter, UV/IR filter and ASI174mm monochrome camera. The optical telescope used was an ES 127mm Doublet achromatic refractor telescope.
