Messier 15 (or NGC 7078, the Great Pegasus Cluster) through the Meade LX600. Stacked with Siril, in an first attempt to use flat frames in addition to dark frames.

I advise you to try Siril. If you want to share the data I can try, even if I have no experience with mono. 😅

On continue d'améliorer ce script sous Siril 😀
Récupération des éphémérides, comparaison avec les différents catalogues et calcul de l'erreur par rapport aux prévision.

Deux modes :
- Lorsque l'éclipse est clairement identifiable
- Lorsqu'il faut effectuer une régression pour la déterminée

Pour NINA tu as un plugin dans la nightly. Pour SIRIL ça devrait venir quand Cyril aura intégré ma merge request.
October 29, 2026 at 9:20 PM
Va falloir que je teste ça sous NINA et Siril.
October 29, 2026 at 9:19 PM
Oh c'est super ça 😁
C'est aussi un de mes objectifs de titiller la curiosité du plus de gens pour la photométrie 🤩
Et effectivement avec des outils comme siril, ça peut se faire facilement.

Fait que je regarde ce que j'ai sorti de tes données.
Ce serait cool d'avoir les barres d'erreur !

Phantom of the Opera Nebula(Sh2-173) is a HII emission region in Cassiopeia ionized by massive stars inside the local molecular cloud and is considered to be a star forming region.(per Wiki). A spooky post for Halloween.

Exp: 15 hrs over 4 nights, Taken Sept-Oct 2026

DSS is not designed for mono but should be able to do it. I wanted to try using Siril to stack it but the process I know needs astrometry to do it and none of the servers seem to be working for me today...

The Ghost Nebula (SH2-136) in the constellation Cepheus at ~ 1300 light years distant. I see multiple ghosts in this nebula. It's one of those objects that if you stare at it long enough you see more. A good object to post around Halloween

Total exp: 6.5 hrs, July 2026

Looks promising based on a quick look with the in-app image processing. I'll reprocess it later in Siril though.

Messier 52, an open cluster in Cassiopeia. All of the stars in the cluster formed about 160 million years ago, which is not that long ago in the grand scheme of things!

Just 45 minutes with my Seestar S50 🔭 🧪
Software: Siril, GraXpert, GIMP

Yes, avec Siril.
J'ai encore pas mal de choses à améliorer mais j'arrive à bien la détecter en local sur mes sessions.

J'ai pu contribuer au projet de @pahcas.eurosky.social ( avec un cadre bien plus pro et scientifique ) mais je voulais réussir à retrouver cette preuve / démonstration.

OK, I pulled in a bunch of additional data I already had on the nebulae and stacked everything together in Siril.

I could still really do with some more data in order to have enough signal to noise everywhere. Then I could draw out the fainter extended nebulosity […]

Getting my head around Siril stacking software. This is 100 x stacked shots with the 500mm lens. It was a misty auld night though, so I think I can do better than this yet!

Captured the Hunter Moon last night and early this morning from my back yard using the #Dwarf3 and around 300 images taken at 1/400 of a second each, stacked and processed in #Siril.

Satellite trail in your photo?
Have the frames: stack with rejection, free in Siril.
One frame: subtract the trail. My tests: Seestar trail gone (1 star tinted), tight Starlink train failed, lit branches erased.

The M81 group: Main members are Bode's Galaxy(M81), Cigar Galaxy(M82), the colorful Garland Galaxy(NGC 3077), close to M81 is the dwarf galaxy Holmberg IX, and in the lower right the dwarf galaxy NGC 2976.

Total Exposure ~ 8 hours over several sessions in October 2026.

Trumpův svět (646. den): Prezident na předvolebním mítinku v Texasu strašil voliče odebíráním zbraní, ropy a masa, které prý chystá demokratický kandidát. Překroutil jeho výrok, že Bůh není binární, a tvrdil, že demokrat podporuje transgenderové mrzačení dětí.
Straší vypálením Detroitu i transgenderovým mrzačením. Trump a Vance varují před vítězstvím demokratů. Trumpův svět (646. den)
Trump v Texasu opět šířil zavádějící informace a útočil na oponenty. Pustil také sestříhané reportáže stanice CNN. Při výhledu na tanker s ropou znovu zmiňoval Venezuelu jako 51. americký stát. Podle…
