Cherry Springs – June 2021

First light test of the QHY268C CMOS camera on the Tak FSQ-106ED. For a very short total exposure time and a low southern target results were better than expected.

Spring 2021 – Daysprings Observatory

I put a QHY268M CMOS camera into the Observatory to replace the significantly larger pixel sized Apogee U8300 that has been hanging around since the very early days and is starting to hiccup. These were all test images with 3 minute exposures from my fairly light polluted suburban back yard observatory. (SQM is 20.0 to 20.4 depending on season and quality of the night.) Most images are 2-3 hours total exposure in LRGB. Some images were a total loss due to filter wheel problems and filter shift causing incompatible flat frame corrections. Corrective actions have been taken to secure the filters and ensure proper indexing. As it is, none of these images are great but I can’t bring myself to throw them out so think of this as a first light post of sorts for the QHY268M.

M106

M106 is an intermediate spiral galaxy in Canes Venatici with a detected supermassive black hole at it’s core. It resides approximately 22-25 million light years away. It’s one of the largest and brightest nearby galaxies.

The Leo Triplet

The Leo Triplet, also known as the M66 group, contains M65, M66, and NGC 3628 commonly called the Hamburger Galaxy. The galaxy group resides approximately 35 million light years away.

Emission Nebula IC 1795 – November 2020

IC 1795 – A star forming region in the northern constellation of Cassiopeia. Hubble Pallet Emission line imaging from Clinton, TN. Poor seeing conditions over several nights in Nov 2020 but almost 33 hours of total exposure time. AP130GTX with Apogee U8300 camera riding on AP1200GTO in backyard observatory.

Cherry Springs Sept 2020

This trip to Cherry Springs State Park promised an amazing clear stretch but was marred by dense smoke obscuring much of the sky from the wildfires raging in CA and other parts of the US.

The sun looked like a planet hanging in an overcast sky due to all the smoke.
If there had been any sun spots they may have been naked eye visible without a sun filter!
The sky was clear yet the blue wasn’t quite able to break through the hazy smoke.
