  1. The Rosette Nebula, designated NGC 2237 is located 5000 light-years from Earth in the constellation Monoceros.

    The image was captured using the Explore Scientific ED165-FPL53 air-spaced tripled refractor and ZWO ASI2600 CMOS one-shot dedicated color astronomy camera, at a temperature of -24.5 Celsius.

    A Radian Triad Ultra Quad-Band narrowband filter was used to reduce light pollution and enhance the image. The exposure time was 124 minutes.

  2. This past Friday was a beautiful evening, so I decided to set up the astronomical equipment and capture a close-up, 65-minute exposure of the Andromeda Galaxy and NGC 205 also designated as Messier 110 to the lower left.

    Messier 110 is a dwarf elliptical galaxy that acts as a satellite of the Andromeda Galaxy also designated M31.
    The image was captured using the Explore Scientific ED 165mm APO refractor at F/7, using an ASI2600 CMOS color camera, with a temperature set at -15 Celsius.

    An LPO filter was used to reduce light pollution and calibrated images, lights, darks, bias, and flats.  
    Stacking software used Astro Pixel Processor.

  3. The galaxy NGC 2336 lies at approximately 100 million light years from our planet, located in the constellation Camelopardalis, the Giraffe. According to NASA, NGC 2336 stretches an immense 200,000 light years across. To the lower right lies the intermediate galaxy IC 467, which is also 100 million light years from Earth.

    The image was captured using the ASI2600 CMOS one-shot color camera and 60 minutes of exposure time with a camera temperature of -28.3 Celsius.

    The telescope used was the Explore Scientific ED 165 mm APO Airspace Triplet refractor and Starizona 0.65x reducer & flattener Apex. ED-L version. Unfortunately there were no calibrated frames used or a light pollution (LPO) filter.

    Messier 13, the Great Globular cluster in Hercules was captured using 85 minutes of exposure time. The galaxy NGC 6205 is also present in the image, located to the upper right.

    See if you can find the distant spiral galaxy IC 4617 (barely visible), just to the right of M13. The optical system used was the Explore Scientific ED 165 mm APO Airspace Triplet refractor and the ZWO ASI2600 CMOS color camera.

    The image was processed with Astro Pixel Processor, using light, flat, dark, and bias calibrated frames.

  5. The stunning and beautiful Eastern Veil Nebula is in the constellation Cygnus, was captured using the ZWO ASI2600 CMOS color camera at a temperature of -25 Celsius with an exposure time of 2 hours.

    The telescope equipment used was the Explore Scientific ED 165mm APO Airspace Triplet refractor, Optolong L-Pro light pollution filter (LPO) and Sky-Watcher EQ8-R Pro equatorial mount. Polar alighment and tracking was achieved using plate solving.

    The processing software used was PixInsight and Adobe Photoshop along with light, flat, dark and bias calibrated frames.

  7. The Sun's chromosphere captured in Hydrogen Alpha light, using a Daystar Quark Chromosphere filter at 7 Angstrom, and a monochrome CMOS camera. The telescope used was a 5" APO Triplet refractor, using 9 sub-frames.

  8. The image of the Sun was captured in Calcium-K light, using a Baader filter combined with a Daystar Quark Calcium-H line filter.

    The camera used was an ASI174 CMOS monochrome camera, and a UV light filter to reduce heating.

    The Explore Scientific ED 102mm APO Triplet refractor at F/28 was used and mounted on a Sky-Watcher EQ6-R Pro equatorial mount. 

  9. A closer look at the sunspot AR2833, reveals the dark feature of the Umbra and some details around the lighter Penumbra.

    The image was captured on 06/18/2021 at 1:15 PM ET, using a Daystar Quark H-Alpha filter with an internal 4x telecentric barlow, at 0.5 Angstrom bandwidth and a UV/IR filter to reduce scattered UV light & heating.

    The telescope used was a Lunt 80mm MT APO refractor and an Altair 174M Hypercam - monochrome, fan cooled camera, using 504 recorded SER images. The software used was AutoStakkert 3.1.4 & Registax 6 for stacking the image and wavelet enhancement.

  10. The Sunspot AR2833 was recorded on 06/18/2021 at 1:40 PM ET. You will notice the faculae all around AR2833 and on the suns disk. The Umbra & Penumbra are also visible in AR2833.

    The activity has been recorded on Spaceweather.com as AR2824, after being on the far side of the sun, and now has been renumbered to AR2833.

    The image was captured using a Daystar Quark Calcium H-Line filter, at 3968.5A (angstrom). The solar scope used was a Lunt 80mm MT APO refractor and Altair 174M Hypercam monochrome, fan cooled camera using 136, recorded SER images.

  16. The spaceweather.com, had an alert for large solar activity in the optical light and radio frequency range on 05/22/2021.

    This large solar flare was taken 05/23/2021.

    Unfortunately, the main solar imaging camera I use, the ASI174 CMOS monochrome cam, had damage to the USB port. I ended up using my backup solar camera, the Altair 174 CMOS one-shot mono cam to capture the solar activity. 
    There are Newton rings present in the images, I did not have enough time to install the mechanical tilt adapter to prevent the newton rings.

    If you check out the spaceweather.com link and select 05/23/2021 for the date, you will see the strong solar flare captured and be able to listen to the sound of the huge solar flare radio bust!
