Probably my last view of comet C/2021A1 (Leonard). Schlepped out to Goose Pond Fish & Wildlife area in Greene County, Ind., a dark site with low horizons on a cold but crystal evening. The comet was very low by the time it got dark enough to emerge from the twilight so it appears redder than when higher in the sky. But I got enough exposures, to show some detail in the tail and coma. This is a composite, processed twice: registered on the comet and separately registered on the stars, combined in Photoshop.

The Cave Nebula (Sh2-155) is a Hydrogen cloud (in the center) with a brighter rim and a star forming region in the large molecular cloud known as Cepheus B. The stars of the Cepheus OB3 association are less than 100,000 years old. Low mass star formation is occurring at a high rate within the dust clouds of Sh2-155.
The blue reflection nebula (lower left) is VDB-155.
Just south (in this image to the left) of the Cave nebula we can see some strange orange Nebulosity, the home of some Herbig Haro Objects. HH168, HH169 and HH174 are locations, where a star is born, still surrounded by dust and nebulosity, already shaped into a rotating disk. This material blocks the light of the new-born stars and the pressure can be released only at the disk poles and Jets of material are escaping from their northern and southern poles.

The Iris Nebula can be a tricky target due to the amount of dust and dark nebulosity around, which can be easily mistaken for noise or light polution, but also equally it is very easy to over expose the core. Whilst I have some sort of reflection in the lower left corner, I am very happy with the way this image turned out, there's a lot of detail around the nebula

On April 15th, 2023 minor planet (270) Anahita passed by galaxy NGC 4939. I captured this encounter with a remote telescope in Auberry, California. Unfortunately this was about 16 hours after the close encounter, but the minor planet is still in the field of view. To my suprise I found an other minor planet, which is the still unnamed (35954) 1999 KY15.
The image is a stack of 20 frames of 180 seconds each. The minor planets are only shown in 7 frames each, to better show the movement.

Markarian's Chain is a group of galaxies in the constellation of Virgo, the galaxies when viewed from earth are in a curved line hence the name Markarian's Chain, they obtained the name from Benjamin Markarian who dicovered the common motion of the galaxies back in the early 1960s, there are quite a number of galaxies within the group, but the chain itself consists of M84, M86, NGC4477, NGC4473, NGC4461, NGC4458, NGC4438 and NGC4435 which are all visible in this image.

When I first got into astrophotography, galaxies were what I was most interested in imaging. I quickly realized that to image most galaxies well (except for the few large ones like M31 and M33), I needed a long focal length lens and accompanying highly accurate tracking. My budget didn't allow for that, so I adjusted my aspirations and focused on widefield shots with a simple tracker. Still, I love a good galaxy picture and anticipate stepping up to more sophisticated equipment someday.
I turned my back on Orion last night (it was difficult) and shot north again for the first time in awhile. I didn't have high expectations for what I'd get from imaging Galaxy IC 342 with a 135mm lens. I'm guessing somebody has tried it, but I couldn't find any examples online.
I'm happier than anticipated with this image. Although small, there is a good variety of objects in this extent; in addition to IC 342, it contains 1) the yellow reflection nebula around star BE Camelopardalis in the center, 2) a dark nebula on the left (I think IREC 193), 3) star cluster NGC 1502 in the upper left, and 4) the asterism Kemble's Cascade below NGC 1502 (although it's difficult to distinguish among the surrounding smaller stars).
Here's a thorough report about the reflection nebula around star BE Cam that clued me into its existence: www.sternwarte-baerenstein.de/upload/be-cam_reflection_ne.... Also an excellent APOD of IC 342: apod.nasa.gov/apod/ap170708.html
I'm looking forward to doing some more widefield galaxy shots this spring.

NGC7882 is a large Emission Nebula in Cepheus, whilst I tried to obtain some OIII data, there appears to be very little OIII Data within this particular target. NGC7822 lies approximately 2900 light years from Earth and spans somewhere in the region of 100 light years across, there are a number of "Pillars of Creation" scattered throughout this large nebula.

I was excited to capture 30 minutes of imagery of my first comet, C/2017 T2 PANSTARRS, on Thursday, January 30, before clouds moved in.
Since I wasn't sure I'd get anything because of clouds, I didn't bother to drive to my Bortle 3/4 dark site, but instead shot from my Bortle 5 backyard, 60 x 30 seconds. I combined this imagery with some better imagery of the Heart and Soul Nebulae from this past fall (47 x 60 seconds under Bortle 3/4 skies), to create this small mosaic (the Heart and Soul Nebulae turned out a bit ugly from my Bortle 5 backyard). I was impressed with how well Astro Pixel Processor combined the imagery of such differing quality.

Finally had a clear night over a week after the launch of the NASA's James Webb Space Telescope and managed to catch an image of it on the way to its observation post. This is a composite of about six hours of exposures from suburban Bloomington, Indiana. JWST shows up as the streak to the left of the bright (relatively) orange star (HD 44256) as it moves relative to the background stars. The trail is interrupted because several bad frames (poor tracking, etc.) were excluded.

This complex of reflection nebulae lies some 6,000 light-years away, in the constellation Cygnus.Obscuring interstellar dust clouds appear in silhouette against reddish hydrogen emission nebulae, along with the dusty blue reflection nebulae. Ultraviolet radiation from the massive, hot, young stars of the extensive Cygnus OB2 association ionize the region's atomic hydrogen gas, producing the characteristic red glow as protons and electrons recombine. Embedded Cygnus OB2 stars also provide the blue starlight strongly reflected by the dust clouds.

The Jellyfish Nebula (left-center) is a supernova remnant. The Monkey Head Nebula is the bright emission nebula near the bottom; the monkey head is upside down looking right here. Both are quite close - the Jellyfish Nebula is an estimated 5,000 light years from earth; the Monkey Head is an estimated 6,400 light years from earth. The large star cluster near the top is Messier 35 (NGC 2168). NGC 2158 is the other smaller star cluster to the lower right of Messier 35.

One of my favorite targets - the integrated flux nebula (IFN) or galactic cirrus is faint dust illuminated by our galaxy, and there happens to be a nice concentration of it in the direction of Bode's Nebulae (Bode's (M 81) and Cigar (M 82) Galaxies). The Angel Nebula, which is made of IFN, is in the lower left corner. This is an improvement over my last attempt at this target - shooting raw and more integration time made a difference.

10*180s subs = 30 minutes total integration time. Using the Avalon m-zero mount with near perfect guiding, amazing considering I guestimated polar alignment. Imaging telescope was the William Optics GT71 with FF 6A2 that I have finally got working with correct back focus. Still some walking noise from the bad PA,
Camera was the ASI1600mm at 0 degrees. Calibrated lights only in APP.
Again balcony astro, Brisbane city, Bortle 8 and a full moon.
I played a bit with the Bodes and Cigar Galaxy again and cropped it a bit more too.

COBS (Comet OBSveration database) contributions indicates that C/2021 Leonard had a significant outburst just prior to its recovery in the evening sky on December 15/16 2021. The comet flared to mag 3.5 and then quickly subsided to mag 5 by December 18. These three images were captured with a Vixen VSD 100 mm telescope and a Nikon Z7II camera mounted on a Vixen SXP. About 2.5 minutes of images were acquired with subs and stacked with AstroPixelProcessor and finished with Photoshop. With clouds and haze in Tucson and Comet Leonard gaining altitude each day the differences shown are not normalized and are a qualitative product of the captures.
Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 41 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken Jan 10, 2019.
This is a reprocess of data from earlier in the year - this time I used the 'remove light pollution' and 'HSL selective color' tools of Astro Pixel Processor after integrating light frames in DSS and before editing in GIMP. Also, my flats were introducing artifacts so I didn't use them, but instead corrected vignetting with the 'remove light pollution' tool.
I'm much happier with this version - the color and definition of the nebula are much better, and seem to be accurate in comparison with other images.

30 * 60 sec subs
Gain = 300
Temp = -10 Deg C.
Mounted on the Sky Watcher Star Adventurer and calibrated using AstroPixel Processor. Lights only.
Taken at Dayborough, Queensland, Bortle 4
This emission nebula is found in the constellation of Vulpecula, the Little Fox.
34*180 sec subs at ambient temperature. 102 mins total, then high altitude clouds rolled in.
Captured using Nebulosity and could not get the program to cool the camera :(
The telescope was the William Optic GT71 with the ASI183MM camera and Antlia 3.5nm filters.
Calibrated using lights, darks, flats and dark flats In APP.
Again, this was using the Avalon m-zero mount with only a rough PA.
Polaris & ses nébuleuses sombres

Aujourd’hui, je vous fais découvrir les nébuleuses sombres qui accompagnent l’étoile polaire.
Cette étoile sert depuis des millénaires comme point de repère entre autre pour la navigation. Elle nous sert aussi à nous aligner pour nos montures équatoriales puisque toutes les constellations tournent autour de Polaris.
Que viennent faire les nébuleuses sombres dans cette histoire ?
Elles sont présentes autour de notre étoile polaire. En anglais, elles sont appelées IFN pour « Integrated Flux Nebula ». Elles sont principalement composée d’hydrogène moléculaire et d’hélium.
Cependant, ce n’est pas aisé de pouvoir les photographier. D’une part, comme leur nom l’indique, elles sont obscures.
Ce sont des nuages denses qui absorbent la lumière des étoiles en arrière plan.
D’autre part, au moment de la prise de vue, elles sont invisibles. Très pratique me direz vous… Même constat au moment de l’empilement, il n’y a que le traitement qui permettent de les mettre en valeur.
A titre d’exemple la tête de cheval (IC434) dans la constellation d’Orion fait partie des nébuleuses sombres les plus connues.
