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.

We’ve had far too many rainy days followed by isolation and the closure of astronomy parks and related facilities. Even if it cleared, we have nowhere to go. So here’s a quick reminder of the winter nebula that are leaving now not to be seen until next year. I wish I had time to do a mosaic and capture the whole nebula but I didn’t. It truly is a LARGE nebula. This image is 2.4 degrees across and could hold more than 18 full moons. (The moon varies between about 29′20″ – 34′6″ in size)

IC 1805 / Sharpless 190, more commonly known as the Heart Nebula, lies approximately 7,500 light years from Earth. This data set was comprised of 43x20min Ha, 23x20min O[III], and 24x20min S[II] for a total exposure time of 30 hours over several nights in November 2019.

Melotte 15 – The open star cluster that lies at the center of IC 1805 and provides the radiation that gives the nebula it’s soft glow.
NGC 896 – The brightest part of the Heart Nebula; it was cataloged separately because it was the first part of the Heart Nebula to be discovered.
The Heart Nebula – This image spans almost 2.6 degrees x 2.6 degrees. For scale, it would take 27 full moons to fill this field of view.

Pickett State Park Dark Sky Celebration Weekend (8/30/2019)

We had some great weather for the annual star party at Pickett State Park, TN last new moon. This star party is still young and looking to grow. The park rangers are doing a great job, it’s a great venue for presentations and a great field for observing / photography. I’m not sure why it still remains a hidden gem of sorts.

Overall sky quality, other than some early clouds, was excellent. With SQM measurements around 21.77 mag/arcsec^2 this was the darkest I’ve seen Pickett. I would note too that of the other dark sky sites I routinely visit, this quality of night is nothing to complain about.

The rig is facing N,NE towards the Constellation Cepheus imaging Sharpless Object SH2-154
SH2-154: AP900GTO, FSQ-106ED with SX-46 CCD. Image scale of 2.33 arcsec/pixel. Exposure time ~13.5 hours. Also plainly visible on the right edge of the frame is SH2-155 The Cave Nebula. Sometimes the faint objects like 154 don’t get a lot of love because they’re not much to look at. At least it’s got a nice tight open cluster NGC 7419 nearby to draw some attention.

We had a great clear spell 7/23 through 7/27 with only moderate lunar interference in the early hours of the morning. This is 14 hours of exposure divided equally across Hydrogen-alpha, Oxygen [III], and Sulfur[II] emission lines. Scope was an AP130GTX with Apogee U16 CCD on an AP1200GTO mount. Located outside Clinton, TN. The following are crops from the main image.

Finally, here is the nearly full frame image encompassing the whole area.

With weather looking wet and wild for the 2019 Cherry Springs Star Party and things looking slightly less soggy at Calhoun we decided to cancel on Cherry Springs and gamble on Calhoun. Good thing we were setup on the top of a ridge so we never had to deal with muddy conditions considering all the rain we didn’t know was coming.

The first couple days were all clouded out.
Night time conditions were very soupy
Couple nights later things were improving but still very humid and hazy. The Milky Way was at least starting to pull out of the haze.

Equipment setup and hoping for clearing

Finally some stars poking through the clouds. Look at that new bright light in the East / NE; it’s really projecting up!
