#astronomie 9 mètre de focale c'est beaucoup (T200 à F/45 😂 ) faut vraiment avoir peu de turbulence, jusque minuit c'était ok mais après #jupiter était trop basse ou trop près de la maison (qui dégage de la chaleur ...) dommage, seul la première image du transit d'ombre est correcte. A droite les deux satellites IO et Ganymède, Europe est superposé à Jupiter et son ombre se projette sur le limbe opposé camera #zwo #ASI662mc, projection oculaire 15mm, traitement #siril

Pan Marcin był chory
I leżał w łóżeczku
Wystawił więc Seestara,
By coś tam smażył w ogródeczku...
A co widział i wypalił znajdziecie na obrazeczku.

Znaczy na kilku, bo wychodzi na to, że mam 2h materiału (a 3h pracy) a od 8:30 do 16:30 się bawiłem w obróbkę i jest kilka wersji.

Celem miała być mgławica IC 1795[1], czyli Mgławica Rybia Głowa (Fish Head Nebula), ale po małej korekcie, jako cel została uznana gwiazda oznaczona jako HIP 11505.
Obróbkę robiłem za pomocą:
A) aplikacją do obsługi teleskopu Seestar S50
B) Siril 1.2.6+GraXpert
C) PixInsight z różnymi ustawieniami.

1) Obróbka aplikacją do obsługi teleskopu Seestar
2) Siril+GraXpert
3 i 4) PixInshight + GraXpert (2 wersje)

Czuję, że czeka mnie duży wydatek na PI+dodatki.

So, following the excellent #siril tutorial, I might still have done too much to the stacked image in the end.

Anywho: Tracking went well, pictures are a little out of focus I guess. Still, I was able to produce somewhat of a nice image, given the circumstances.

I'm happy 😃

#astronomie #astronomy Une autre image de mercredi dernier #mars évidement! Pour cette image j'ai testé le logiciel ASIVideoStack fournit avec la caméra #ZWO, apriori rudimentaire comparé à #siril le logiciel donne très rapidement une image assez bonne de la planète rouge : ici on reconnaît bien la calotte polaire au nord, au-dessus d'une zone sombre Mare Acidalium et celle qui recouvre toute la face sud Mare Erythraeum. Prochain objectif refaire ça avec 10 m de focale au lieu de 4!

réunion du club #astronomie ce soir consacrée au traitement des images planétaires, l'occasion de reprendre mes images d'hier et d'en améliorer le traitement. J'ai appris ce soir comment #siril permet de modifier finement l'histogramme et comment faire la balance du blanc pour #Jupiter (utiliser les deux bandes blanches au-dessus/dessous des bandes équatoriales !)

NGC 3227 is a rarely-imaged spiral galaxy located in the constellation Leo that interacts with the elliptical galaxy, NGC 3226. My grandpa imaged this galaxy from late April to early May and got 9.6 hours on it. I like the color of this galaxy a lot and it looks like it has a gradient of color that goes from a light blue to more of a golden brown.

The Rosette nebula!! A year ago I couldn’t even imagine getting a shot like this, or not even in October when I first captured it! The Optolong L-eNhance has greatly helped achieve this, along with the auto guider which allows me to not worry about backlash and take even longer exposures that the filter allows.

Over 3 nights last week I got over 110 5-minute subs which got me close to 10 hours of data total! The data is also very clean and it allowed me to stretch a lot of faint details from the center of the nebula without bringing out too much noise.
