This is my last picture taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY); The image shows IC1795 and NGC896 in Hubble Palette Technique.
I have been really impressed from the various colors that came out from this photo. I really love this mix, especially the part of the OIII.
I hope you like it and clear skies!

Jupiter, photographed from Long Beach, CA
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. Color balancing in Registax, then final touches in Photoshop.

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.

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.

This wide-field image frames the prominent emission nebula IC 1396, at left, and the faint arcs of Sharpless 2-129 at right, in southern Cepheus. IC 1396 contains the dark Elephant Trunk Nebula at about the 3 o’clock position in the nebula. At the top edge of the nebula is the orange giant star Mu Cephei, aka Herschel’s Garnet Star. The dark nebula at top left is Barnard 169-70-71. The dark nebulas at the bottom of IC 1396 are B160, B162 and the snake-like B365. A small blue reflection nebula below and left of the Sharpless complex is VandenBurgh 140.
This is a blend of filtered and unfiltered shots, all with the William Optics RedCat 51mm astrographic refractor at its native f/5 and with the Canon EOS Ra: 6 x 8-minutes at ISO 1600 without the filter and 4 x 12-minutes at ISO 5000 with the Optolong L-Enhance filter, which reduces light by about 2 to 3 f-stops but really makes the H-alpha nebulas stand out. All stacked, aligned and blended in Photoshop. LENR employed on all frames on this warm summer night to ensure the most accurate dark frame subtraction of thermal noise but at the cost of doubling the capture time.

Saturn is a bit over a week past opposition in this image. You can see the shadow of the planet on the rings just starting to creep onto the left side. It looks like I got the hexagon pretty well, and there's a bit of the Encke gap on the right. That's the first time I can definitively say I caught it. Not sure why it didn't show up on the left, but there's still data to play with from this night of excellent seeing.
3 stacks each for R, G, and B channels.
R stacks are 450 frames each, 43.1 ms exposures, 90% gain
G stacks: 180 frames each, 95.6 ms exposures, 90% gain
B stacks: 75 frames each, 114 ms exposures, 94% gain
Each color channel was derotated and combined with the same channel stacks in WinJUPOS, then those averages were brought together in WinJUPOS. Stacking done in AutoStakkert; initial sharpening in PixInsight; some final processing and touch ups in PixInsight and Photoshop.

This is Sh2-132 - The Lion Nebula - taken with the Optolong 2" L-eXtreme Filter! This is a dual band filter and I have to say I have been very satisfied of the result I had! After the calibration the colors were quite good and it was not necessary to calibrate them a lot.
Taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY);
I hope you like it and clear skies!

Here is a small clip from a larger view of IC 1396 in the constellation Cepheus called the Elephant Trunk Nebula. The Elephant Trunk Nebula is about 2,400 light years from Earth and stretches for over 20 light years. This area is also a star forming region containing over 250 young stars both in it, and around it.

A portrait of the complex of emission nebulas in central Cygnus near the bright star Gamma Cygni (at left). The field includes the IC 1318 complex around Gamma Cygni itself and the Wolf-Rayet arc of nebulosity, NGC 6888, aka the Crescent Nebula, at right. The sparse star cluster Messier 29 is at bottom.
This was through the SharpStar 94mm apo refractor at f/4.4 and with the Canon EOS Ra. It is a blend of 6 x 6-minute exposures at ISO 1600 through an Astronomik UV-IR-Cut filter for the base image, and a stack of 4 x 12-minutes at ISO 3200 through IDAS NB1 and Optolong L-eNhance filters for the enhanced red nebulosity, plus 6 x 12-minutes at ISO 3200 through Optolong L-eXtreme and IDAS NBZ filters which contribute only the enhanced cyan OIII emission, all taken as part of testing the filters. Normally, using four filters would not be required! Autoguided and dithered on this warm summer night with the Lacerta MGEN3 autoguider. No darks or LENR applied as the dithering effectively eliminated the thermal noise speckling which was prominent on the individual sub-frames.
Taken from home August 13, 2021. All stacked, aligned, and blended in Photoshop.
NGC6960 and the Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. The Veil Nebula is a supernova remnant which exploded between 10,000 and 20,000 years ago.

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the east of IC 1396A. (In the Spitzer Space Telescope view shown, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars.
