Our Sun was putting on an excellent fireworks display this 4th of July. And it was one you enjoy during the daytime. Of course you would need to have a hydrogen alpha filtered solar telescope. The large prominence at the 2:00 position is approximately 225,000 miles long. That means you could put about 28 earths side by side in that space.

From Wikipedia - The Sea of Nectar (Mare Nectaris) is a small lunar mare or sea (a volcanic lava plain noticeably darker than the rest of the Moon’s surface) located near the Sea of Tranquility (Mare Tranquillatis) and the Sea of Fecundity (Mare Fecunditatis). Several large craters are situated at the borders of Mare Nectaris. The largest one is lava-filled Fracastorius (124 km), which fuses with southern coast of the Sea. A prominent trio of 100-km craters Theophilus, Cyrillus and Catharina is located near northwestern coast.

This galaxy lies approximately 21 million light years away. It is interacting/colliding with another galaxy (smaller object to the top, NGC 5195) which has been continuing for millions of years. Several supernovas have been spotted here in recent years.

Last night presented an exceptional night of viewing here in Central Texas. Temperatures around freezing, clear skies and a moon that set around 9:15pm. I was able to capture 3 hours of data on this object before I had to go to bed to get ready for work the next day.

تغطي هذة الصورة الجميلة منطقة واسعه من السماء. حيث تم اخذ الصورة باستعمال عدسة عريضة ١٣٥ ملم لتغطي نطاق رؤية ١٥ * ١٠ درجة من السماء. تبين الصورة حلقة برنارد في الاسفل و هي سديم انبعاثي غازي يتألف بشكل اساسي من غاز الهيدروجين و يقع في كوكبة الجبار او الصياد. و يعتقد العلماء بان هذة الحلقة الغازية نتجت عن انفجار نجم قبل ٢ مليون سنة. كما و تشمل هذة المنطقة من السماء على عدد من الاجرام الفلكية مثل سديم الجبار على اليمين و سديم راس الحصان الذي يقع في منتصف الصورة و جنب نجمة النطاق. و كذلك يظهر في الصورة حزام كوكبة الجبار و الذي يتألف من ثلاثة نجوم ( المنطقة و النظام و والنطاق) و هي نجوم قام العرب بتسميتها وقد اعتمدها النظام الدولي الفلكي في التسمية. This beautiful region is covering a wide field of the sky. The image is taken by Samyang 135 lens to give 15 x 10 degrees FOV. It is an emission nebula composed mainly of Hydrogen gas and located in Orion constellation. In the lower part is Barnard’s loop SH2-276 which is formed from star explosion before 2 million years ago. This complex molecular gas cloud consists of many celestial objects. In the center of the image is the Orion belt ( The Three Stars : Mintaka منطقة، Alnilam النظام، Alnitak النطاق all taken from Arabic). Beside Alnitak star, there is the Horsehead nebula (IC 434) and on the right is the Orion nebula (M42). Gear setup: Samuang 135mm/f2.8, iOptron GEN45 pro guided by ZWO mini guide scope, ZWO 120MM-S, Optolong L-Pro & Ha filters, ZWO 2400MC @ 0. Total integration 3 hours, subs 30 x 120sec L-Pro, 24 x 300sec Ha. Captured by Sharpcap pro, APT, PHD2 and processed by PI.

My scope setup had been in Hibernation for about 6 weeks while I had been away from home, and this was from a test imaging session last night to see how it was going. Obviously, not bad! Autoguiding was on-point (achieved one of the best guide graphs I've ever recorded) and this is a decent result for a small refractor!

Copernicus Crater – diameter is 96 km, named after the astronomer Nicolaus Copernicus. It typifies craters that formed during the Copernican period in that it has a prominent ray system. Need many more frames to strengthen the details.

First stab at this with my new ZWO ASI183MC Color camera. I'm still learning as it's rather different from a DSLR, but it provides very nice color presentation and is able to tease out more detail than my D750 could.

Here is an early work in progress showing my first attempt at imaging the Witch Head Nebula (IC 2118) in the constellation Orion. The bright star in this image is Rigel. With Orion now in the western skies after sunset, I will probably not be able to add additional data to this until next season. Still, happy to have finally imaged this one!

A view of the unusual Schiller Crater on the Moon -- The first thing you notice with this crater is the elongated shape, it almost looks like a footprint left on the surface. The crater measures about 179 x 71 kilometers and was formed by at least two impacts. The crater was named for Julius Schiller (c. 1580-1627).

The Pinwheel Galaxy is a face-on spiral galaxy distanced 21 million light-years away from Earth in the constellation Ursa Major. This galaxy contains over one trillion stars! (Our own Milky Way has around 200 billion!)

Technical Notes:

Guiding was at high Dec and fairly poor on 2nd day after Meridian flip - should probably do a guiding calibration along the ecliptic and SE before guiding at high Dec.

Rupes Recta (latin for straight cliff) is a dark and almost straight line, stretching across the large crater which is almost dead centre of the above image.

It is a huge fault line or escarpment on the surface of the Moon, which can be seen just after daybreak at it’s Lunar location, when the Moon is about 8 days through its twenty-eight day cycle (around First Quarter Moon).

The low angle of sunlight casts a shadow that gives it the appearance of a steep cliff, which is 240–300 m high, although it may not be as steep as it looks, because it is 2-3 km wide.

Its length is roughly 110 km and it is located in the south-eastern part of the Mare Nubium.

Theophilus Crater – diameter is 100 km and named after the Greek astronomer (c. 412 AD). The rim of Theophilus has a wide, terraced inner surface that shows indications of landslips. The floor of the crater is relatively flat, and it has a large, triple-peaked central crater that climbs to a height of about 2 kilometers above the floor (Wikipedia).

The weather has been cloudy to partly cloudy for a few weeks. This afternoon was relatively clear with a few small cumulus clouds passing by. I thought I'd try and use a Coronado PST solar telescope to image the sun today. I find this scope a challenge to focus and adjust the etalon. There's image shift because the focusing mechanism is a sloppy movable prism. The etalon is goofy and causes half of the sun to look good while the other half is blurry. It's still fun to use. Besides it is all I have for solar observing. The sun has been active as it approaches solar maximum. There is something new to see every day.

Coronado PST; ZWO ASI432MM; 2x Barlow. I was lazy and used Sharpcap’s live stacking feature to process the image.

The thermometer read 99F, so I didn't image for very long. Not only I was overheating, but my equipment was too!

Tycho Crater – diameter is 86 km and it is about 4.8 km in depth, located in the southern region of the moon. The crater was named after Danish astronomer Tycho Brahe (1546–1601). From Wikipedia, “The crater is sharply defined, unlike older craters that have been degraded by subsequent impacts. The interior has a high albedo that is prominent when the Sun is overhead, and the crater is surrounded by a distinctive ray system forming long spokes that reach as long as 1,500 kilometers. Sections of these rays can be observed even when Tycho is illuminated only by earthlight. Due to its prominent rays, Tycho is mapped as part of the Copernican System.”

Another take on Orion, Barnard's Loop and the Rosette using an H-alpha filter to emphasize the hydrogen clouds through the region. Narrowband filters block most wavelengths including light pollution from the city and the moon. I added an hour of data to four hour's worth collected last year and made different processing choices for this version.

Captured over 4 nights, November 2020-January 2021 from my yard 10 miles north of New York City.
