IC 1396A is the Elephant's Trunk nebula, located in the constellation Cepheus. The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396, at an estimated distance of about 2,500 light years.
At the heart of the nebula lies the open star cluster Trumpler 37, where several hot, young stars (less than 100,000 years) are thought to be forming. These stars emit copious amounts of hot plasma winds and energetic particles that ionize the gas in the nebula and causing it to glow with the characteristic red light of hydrogen atoms. The winds are also sculpting the nebula creating the central cavity, but also compressing the gas in dense regions and triggering a new generation of protostars, hidden inside the dust.
At the estimated distance of the nebula, the Elephant's Trunk is about 20 light-years long.
Thanks to all for your continuous support and kind comments. I wish to all my Flickr friends a happy and relaxing summer and looking forward for your beautiful photos and stories!

Thanks a lot, everyone, for stopping by, for looking my work, for your comments and likes! Always appreciated!
I finally got my equipment working as it should; not entirely happy with the image but pleased to grab something for a change. The next job is clean the optics; the contamination was very evident in the flats.

Cette nébuleuse émet brillamment en lumière rouge, : l’hydrogène. La dominante rouge et les contours extérieurs sont tous deux dus à l’ionisation de l’hydrogène par un petit groupe d’étoiles situé près du centre de la nébuleuse, l’amas ouvert Melotte 15.
Cet amas stellaire ouvert comprend une poignée de brillantes étoiles 50 fois plus massives que notre Soleil, beaucoup d’étoiles faibles ne représentant qu’une fraction de la masse du Soleil

This is a starless image of the Great Orion Nebula (M42) with the reflection nebula Sharpless Sh2-279 the "Running Man Nebula" situated above.
The "little" coma-shaped nebula above and separated from M42 by a dark dust lane is M43 or De Mairan's Nebula.
All form part of the sword region in the magnificent constellation of Orion.
I used Starnet to remove the attendant stars in the image and then concentrated on the nebulae in order to highlight the huge clouds of glowing gases and dusty details within this fascinating region.
M42 is an emission/reflection nebula and this huge cloud of glowing gas and dust is a great stellar nursery where new stars are being born. The pink/red glowing colour is due to the excitation of hydrogen gas and the chief visible emission line appears red to our eyes.
The Running Man Nebula above in contrast shines by reflection. It is visible to our eyes because of illumination from within by embedded stars.
Extensive dust clouds can be seen throughout the image being illuminated to varying degrees.
Imaged with a Skywatcher Esprit 120ED with focal reducer and a ZWO 2600MC camera at gain 100 and cooled to -10C.

It is Milkyway season again and here is an image I recently captured from the back garden using my Skywatcher Star Adventurer 2i tracker with my Nikon D750 with a Tamron 24-70mm lens attached. It was created with a total of 10 subs at 90 secs and no calibration frames. You can clearly point out some nebula and dust clouds which I have marked up for reference.
Thank you for looking.

first light with my Skywatcher P200 Newton telescope. i am far far - really far! - away from being satisfied with the result (bad guiding, bad focus, problems with the mount of the flat mirror - hence the artifacts at the brighter stars), at least i now understand the technical challenges better and today is my next chance :)

I spent Sunday night setting up my scope again, aligning it, and tracking the Triangulum Galaxy. The Triangulum Galaxy lies ~2.7 million light years away from Earth and is part of our local group of galaxies. It lies in the constellation Triangulum, from where it gets its name. Charles Messier cataloged it first in 1764. He published his Catalog of Nebulae and Star Clusters in 1771 and listed it as object number 33, hence the name M33.

My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. I polar aligned my mount using SharpCap Pro. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file and used Gradient XT on the image. I then made it a 16-bit file and continued to stretch the file in levels, then curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset, including some dodging & burning, and relied on Astronomy Tools Action Set and Topaz Denoise to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.

First attempt at imaging M31 ever and with guided exposures using PHD2. My 120ED telescope can't cope with the full size of this galaxy even with the focal reducer going so this could end up a number of panes eventually.
32 mins total integration so far, data collected 25 Nov 2016. I intend to gather more and add to this when weather permits, it was -6 degrees this night and everything was covered in hard frost by the time I packed away.
What can I say, it's been a long road getting to this point with my own rig and I'm still not totally happy with the PHD graph. Also I was getting horrendous amp glow from my Canon 700D in both the light frames and the dark frames, it is still a little evident on the right side of the image even though I've tried to process it out and crop a little, there's a difficult balance between stretching the image too far which increases the glow noise and reducing the gradient glow in that spot alone. Next time I gather more data I will try a different method of taking dark frames after each light frame to get the temperatures a little more even.

Because I had a trouble with the focus, I joined two different images (with the same data) with Photofiltre to get the best result about focus.
I edited and joined them with Photofiltre and MS Picture Manager, to get more details.
A first run at this object with my own setup, guided exposures. Guiding graph was quite exceptional with RMS error at 0.03" then later 0.07" but I tossed away 1/2 my lights over 2 nights due to some trailing at the edges. Discovered this was due to the reducer slightly unscrewed. Some high cloud in a couple of the shots made the seeing wobbly so guiding wasn't perfect all night. Will add more data next time we have clear skies. Everything was iced up after 2 nights outside in -4 deg C temps, but dew band heaters kept going. So did I by sitting indoors and watching it all on Teamviewer! I still have a little amp glow on the right from the 700D! Updated the HC and MC on the mount too, but still not totally satisfied with the way it is performing. Everything looks pretty tight but the Alt axis is still 'rocking' slightly in its locked position.

Sometimes the night sky springs pleasant surprises!
One such event took place during my session on imaging the rising waxing moon, dubbed the Snow moon in North America, on Thursday night (25th February).
During an early imaging run an aircraft flew right through my field of view and transited the moon virtually at midpoint!
I couldn't believe it.
Consulting the Flightradar app. identified the aircraft as an Easyjet A320 enroute from Belfast (BFS) to London Gatwick (LGW)
Really happy to catch this by pure chance - not knowing the flightpath lol!!
My camera was operating at full res. at around 3.5 to 4fps and has captured 3 frames in total showing the aircraft entering and exiting.
Fascinating to see the disturbance on the moon's image caused by the hot exhaust gases.
Imaged with a Skywatcher Esprit 120MM refractor and a ZWO 2600MC.
This image is a single frame extracted from my video run.
A lovely unexpected bonus to the evening's session!
