First discovered by Edmond Halley in 1714. It was 50 years later when Charles Messier added the cluster to his list of objects that he was not interested in, giving it the designation M13.

The cluster is 25,000 light years away from us and can be found in the Constellation Hercules. Giving it it's more prestigious title of 'The Great Cluster in Hercules'.

M13 is one of the brightest globular clusters visible to us, especially from the Northern hemisphere. Containing over 100,000 stars it is quite easy to detect with a modest pair of binoculars and a dark sky.

Leave a comment below if you find it with some binoculars.

Taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY), this is my bicolor version of NGC6992. I acquired it using the Optolong H-a and OIII filters.

I am very happy of this result which is my really first time I use the Bicolor technique.

I have acquired the H-a data during almost full moon (about 96%).

This time I was able to use PixelMath and Starnet, in PixInsight. They were very helpful for the processing.

I hope you like it and clear skies!

NOTE: The image was acquired from a polluted sky with high humidity - Bortle 5.

My latest processing and imagery captured from grand mesa observatory using the Sky-Watcher Esprit 150mm ED F7.0 Triplet APO Refractor that Sky-Watcher USA have sent to us for testing. The camera is the QHY168 Monochrome CMOS camera (beta test model) with an APS-C format sensor. The QHY168M matched with the Sky-Watcher 150 Esprit has an image scale of 0.94 arcsec/pixel and a Field of view of 51.6 x 77.7 arcmin. Using Optolong 7nm H-Alpha, 6.5nm SII and OIII filters the data was preprocessed using Pixinsight and post processed in Photoshop by mapping the SII, Ha and OIII data respectively to the R, G and B channels to create a Hubble Palette (SHO) rendering.

Total Integration time: 14 hours

The setup and data that I used is from October’s subscription on “System 2” and one of 3 telescopes currently available through Grand Mesa Observatory’s Subscription services, if you want to sign up go here: grandmesaobservatory.com/equipment-rentals/

At the center of IC1805 lies the open cluster of stars known as Melotte 15 contains stars that are almost 50 times the volume of our Sun. The “Heart Nebula” show the reddish glow of hydrogen atoms energized by bright stars that form inside this emission nebula. Lanes and patches of dark nebulae are also visible in the foreground of this star forming region of the Milky Way.

The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.

About this image:

Imaged in three key wavelengths of the electromagnetic spectrum of light (Hydrogen-Alpha, Sulfur-II and Oxygen-III), over a few nights (due to poor Astronomical seeing conditions, as a result of a very strong jet stream).

About Emission nebulae:

Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm. The blue light is from doubly ionized Oxygen ions (O2+) emitting at a wavelength of 500.7nm.

30 s SER files were taken with a ZWO ASI120MM camera through Optolong CCD RGB filters on a Celestron Edge HD 925 telescope using FireCapture. The top 60% of frames went into 8 stacks of each color filter. These stacks were made in AutoStakkert, then sharpened in PixInsight. Stacks were combined and derotated in WinJUPOS, and the resulting R, G, and B images were combined in WinJUPOS to make a de-rotated single color image.

hh-262x30-g37-o200-46x180-g20-o100-qhy183c_-20C-lnh-85f5_6

Two sets of data combined, one from last Halloween night during a full moon and one taken the night of December 17/18th, 2020. 262x30 sec at gain 37, offset 200 and 46x180 sec at gain 20, offset 100 for a total of nearly 4.5 hours exposure. Taken with a QHYCCD QHY183c camera at -20C cooling, an Optolong L-eNhance filter and a Televue TV-85 at F/5.6. One was landscape orientation and one was portrait orientation, which is why the diffraction spikes are a cross, which makes it kinda cool. :-)

Location was a metro area, Bortle 7-8 red zone, clear and transparent skies each night. Acquired and stacked in SharpCap 3.2 (LiveStacking) with dark subtraction.

IC 59 and IC 63 are found in the constellation Cassiopeia very near the bright star Gamma Cassiopeia. This set of objects is also known as the Ghost of Cassiopeia. Gamma Cassiopeia also has the informal nickname of Navi. The “IC” designation comes from a group of objects discovered between 1888 and 1907, most made possible by photography, and known as the Index Catalogue.

These nebulae are a combination of emission and reflection, they are located about 610 light years from Earth and are about 10 light years across. Gamma Cassiopeia provides the radiation to light up this area of dust and gas, eventually dissipating the area.

Taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY), this is my new version of NGC7635 in Hubble Palette Technique. I acquired it using the Optolong H-a, OIII and SII filters.

I am very happy of this result!

I have acquired the H-a data during full moon.

I hope you like it and clear skies!

NOTE: The image was acquired from a polluted sky with high humidity - Bortle 5.

Non fotografavo dal 2013 questa bella galassia a spirale, chiamata anche galassia del Triangolo (M33, NGC598) it.wikipedia.org/wiki/Galassia_del_Triangolo , ricca di nebulose . Adesso con l nuovo setup era giusto riprovarci.

L'occasione propizia è stato lo Star Party del Gruppo Astrofili Catanesi astrofilicatanesi.net/ (02-04/08/2024)

La prima notte con un cielo discreto, purtroppo ho acquisito (non so cosa sia successo) senza raffreddare il sensore della ASI533MC-pro (circa 15°C). Speravo nella seconda notte ma a causa delle nuvole ho acquisito solo 17 frame.

Ciò malgrado l'immagine combinata era abbastanza buona ma scarsa di informazioni H-alfa. Ho deciso allora di riprendere da casa un pò di segnale in banda stretta per aggiungerlo all'immagine RGB.

I hadn't photographed this beautiful spiral galaxy, also called the Triangulum Galaxy (M33, NGC598) en.wikipedia.org/wiki/Triangulum_Galaxy, rich in nebulae since 2013. Now with the new setup it was right to try again.

The right occasion was the Star Party of the Gruppo Astrofili Catanesi astrofilicatanesi.net/ (02-04/08/2024)

The first night with a decent sky, unfortunately I acquired (I don't know what happened) without cooling the sensor of the ASI533MC-pro (about 15°C). I was hoping for the second night but due to the clouds I only acquired 17 frames.

Nevertheless, the combined image was quite good but lacking in H-alpha information. I then decided to take some narrow band signal from home to add it to the RGB image.

Here is a previously unprocessed photo of three prominent craters familiar to all selenophiles (lunatics?): the trio of (from top to bottom) Ptolemaeus, Alphonsus, and Arzachel. Here they are captured under high-angle illumination from the East (late morning on the Moon), which reduces contrast and makes photography a challenge.

Photographic conditions for this session were challenging, with below average transparency, variable seeing (2.5-3 out of 5) and thin, high clouds. To counteract these difficulties, more images were collected and an IR (infrared passing) filter was used. The best 37% of 17,295 video frames were used to create this photo.

Stacking was done with Auto Stakkert!3. Wavelets and histogram adjustments with Registax 6. Toning, cropping and rotation with Camera RAW and Photoshop CC 2021.

Here is a wide-field shot of the Trifid and Lagoon Nebula in the constellation Sagittarius using the Askar Astrograph paired up with a ZWO ASI071mc-Pro camera, Optolong L-eNhance filter, and controlled with the ZWO ASIair Pro, all running on an EQ6-R Pro mount. Lot's of details for only 25-minutes of exposure time.
