Closest Approach of Comet 41P/Tuttle–Giacobini–Kresák at Magnitude 8.6 in the Constellation of Draco.
Comet 41P is still visible in Binoculars from a dark location, it is heading for Perihelion on the 12th of April.
On April 1st - 2nd, the comet passed by Earth at a distance of about 13 million miles (0.14 astronomical units), or 55 times the distance from Earth to the moon; An unusually closer approach for this Jupiter-family comet. Comets are frozen balls of Ice, Gas, & Dust that start to sublimate when heated by the sunlight as they approach the inner solar system.
The green color is the Comet P41 Spewing C2 Diatomic Carbon which glows green when lit by the sun in the Vacuum of Space!
Here is my shot of Comet 41P as it passed within 13 arc minutes of 4.58 Magnitude Star 10 Draconis, & 4.7 Magnitude Double Star WDS HJ 3342 (WDS = Washington Double star Catalog)
Taken with my Homemade 16 inch Diameter Newtonian Telescope and a Canon 6D DSLR,
20 frames x 30 second exposures (10 minutes) stacked in Deep Sky Stacker, comet Mode.
Captured from 08:26 U.T. to 08:46 U.T. at my Observatories at JBSPO in Yellow Springs, Ohio
Yellow Springs Research Station, MPC #H66

NGC2359 Thor's Helmet - Wolf-Rayet Star WR7 also known as Gum 4 or Sharpless 2-298, located at a distance of 11,960 light years away in the Constellation of Canis Major!
This is an emission nebula that is about 30 light years across, the Bubble Blown by the Wolf-Rayet Star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution.

The nebula has an overall bubble shape, but with complex filamentary structures. The nebula contains several hundred solar masses of ionized material, plus several thousand more of unionized gas. It is largely interstellar material swept up by winds from the central star, although some material does appear to be enriched with the products of fusion and is likely to come directly from the star.
I captured this image at the Okie-Tex Star Party 09-29-2016
Baader modified Canon Rebel Xsi DSLR & 5.5 Newt. Scope, ISO 1600, 1 hour exposure. I included a close-up crop from the original wide field image.

The Sun on Sunday 02-26-2017, Although I can't be in the Southern Hemisphere to see the Annular Solar Eclipse, this is the Full Disk Hydrogen Alpha Sun today from my backyard in Dayton, Ohio and I also grabbed a close-up of the only decent Active Sunspot #2638 on the Sun, a few Proms & Filaments are visible too! QHY5IIL Camera & Lunt 60mm/50F HA scope, + 3x barlow for the sunspot close-up! 600 frames Stacked in Registax 6. seeing wasn't the best, but went for it anyway!

I just love the Constellation of Cygnus "The Swan" aka "Northern Cross" at the bottom & The Constellation of Lyra at Top with Bright Star Vega! This dense star studded field of the Summer Milky Way is a treat in Binoculars as well as to the naked eye from a dark location!
You can clearly see The North American & Pelican Nebula near bright Deneb, The Gamma Cygni Nebula region, Also lots of dark nebula throughout...also the Coat-hanger Asterism & other open clusters are visible in this image. Even the Dumbbell Nebula is visible.
Canon 6D DSLR, 47mm lens, F4, ISO 3200, 2 Minutes on a Star Adventurer Tracking Mount taken at Okie-Tex 09-26-2016.

NGC6992/95 The Eastern Veil Nebula - Supernova Remnant
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It is approximately 1,470 light years distance from Earth.
The Veil a large but relatively faint supernova remnant, a Star exploded as a Supernova roughly 3000 to 6000 BC, and this is the expanding gas cloud which now covers about 3 degrees of sky or roughly 6 Full Moons. This is only one section of the Cygnus Loop complex known as the Eastern Veil Nebula.

Taken at Okie-Tex star Party
5.5 inch Newt. & Modified Canon Rebel Xsi, ISO 1600
