I like anything that is like an obstruction, something that I have to act through is good. -- Peter Sarsgaard
I had only recently purchased some narrow-band filters and was keen to give them a test run; for this, I chose NGC281. The aim was initially to capture data in LRGB along with Ha, OIII, and SII; the telescope and weather had other plans. I hadn’t looked at the data since the initial night, and using a process in Pixinsight inspired by Cuiv’s recent mastering Pixinsight YouTube video, I was able to bring together this HOO image of the nebula; it is a target that I plan to revisit this winter to capture more Ha and OIII, along with LRGB and SII data.
NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an HII region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus arm. This 20×30 -sized nebulosity is also associated with open cluster IC 1590, several Bok globules and the multiple star B 1. It collectively forms Sh2-184,[3]spanning over a larger area of 40 arcmin.[4] A recent distance from radio parallaxes of water masers at 22Ghz in 2014 is estimated to be 2.82±0.20 kpc. (9200 ly.) from us.[5] Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character. Source: Wikipedia

For Macro Mondays "Numbers" theme. A mechanical integrator is a complex device that was used to calculate ship's stability before digital computers became practical. The complete device is similar to this image: commons.wikimedia.org/wiki/File:Mechanical_integrator_CHM...
The lens used was an old manual Zuiko 80mm f/4 macro on a sliding extension tube and micro 4/3's adapter, in spite of what the exif info states. Four Olympus high res shots were stacked in Photoshop. I would of liked to gotten one more but ran of focus adjustment.

Both haze and air plus Moonlight on the haze is adverse to a crisp image (note stars). The anti-tail seems to be fading as expected but the conditions do not help its imaging. 1 min 20 sec total integration captured with a Vixen VSD astrograph and Nikon Z8. The comet already appears smaller in the field of view in just two days, it is racing away quickly and will dim as well.
The tail structure is interesting with its central core it has a leaf-like structure. The symmetry is nice.
Nella mia vita di astrofilo non ero mai riuscito a dedicare il tempo necessario alla bellissima "Nebulosa Omega".
Questa nebulosa ad emissione, nel cui interno c'è attività di formazione stellare, è nota anche come nebulosa Cigno, nebulosa Ferro di Cavallo, nebulosa Aragosta o con le sigle "M 17" o NGC 6618, e si trova nella grande costellazione del Sagittario.
Grazie alla sua luminosità, al filtro a banda stretta, che ha tagliato buona parte dell'inquinamento luminoso, e all'integrazione generosa il risultato ottenuto è stato per me appagante. Se nell'immagine lineare era visibile soltanto il cuore della M17, lo strecth ha fatto risaltare anche le nebulose ad emissione più deboli che circondano M17. E questo ha evidenziato anche le nebulose oscure che con i loro intrecci tortuosi, insieme alle sfumature e bordi delle nubi Ha, eccitate dalle giovani e calde stelle al loro interno, danno un effetto di profondità a tutta la nebulosa.

In my life as an amateur astronomer I had never managed to dedicate the necessary time to the beautiful "Omega Nebula".
This emission nebula, in which there is star formation activity, is also known as the Swan Nebula, the Horseshoe Nebula, the Lobster Nebula or by the acronyms "M 17" or NGC 6618, and is located in the large constellation of Sagittarius.
Thanks to its brightness, the narrow band filter, which cut out a good part of the light pollution, and the generous integration, the result obtained was satisfying for me. If in the linear image only the heart of M17 was visible, the stretch also highlighted the fainter emission nebulae surrounding M17. And this also highlighted the dark nebulae that with their tortuous interweavings, together with the shades and edges of the Ha clouds, excited by the young and hot stars inside them, give an effect of depth to the entire nebula.

Really beautiful object catalogued as 881 on the Lynds' Catalogue of Dark Nebulae.
It's one of the jewels that you could find on gamma Cygni nebula, on SADR region of Cygnus, one of my favorites regions of the sky.
"A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds." (wiki)
It was necessary to integrate more than 70 hours to show all faint and nice details on the estructure.
Here was captured using the more natural palette, please also check my HSO palette on this link:

This image is of C/2025 A6 (Lemmon). I imagined this last Friday. Currently, it’s a pretty bright comet that’s shining at a magnitude 5. From the city and urban areas, it’s not naked eye visible, but from a dark sky site it can be seen through binoculars and long exposure photography.
This image was a challenge for me to get. After setting up my rig and powering everything on, I discovered the ASIAIR couldn’t detect my guide camera. At the time I couldn’t figure out why the guide camera wasn’t working. That meant I either couldn’t lock onto a guide star or I would have to manually dither. I was determined to make this image work especially since I paid an entrance fee of $15 to get into the local state park. I ended up setting an auto run sequence of 3 (30 second) exposures. After each auto run sequence I moved the framing ever so slightly in the sky atlas of the ASIAIR app. I repeated this until I got about 35 minutes worth of data. To top it off, the area I was set up gets a little breezy as the night goes on. So, some of the frames werent exactly sharp. Nevertheless, I managed to get enough data to build an image. Later, I discovered my USB cord for the guide camera was bad. The next day I ordered spare USB cords for my rig so I didn’t have another dilemma again.

M94 is a spiral galaxy located 16 million light-years away in the constellation Canes Venatici.
It was discovered in 1781 by Pierre Méchain.
The galaxy has an apparent magnitude of 9 and can be spotted through a small telescope.
It has a 19th hours of integration time using my dual rig set up at the remote observatory.
