Finally, I went for the moon. Got two videos of 30 sec, stacked them using autostakkert and stitched them in Lightroom #Astrophotography #Moon #AM5N

Second target were the Pleiades. This time I pushed it a little bit and switched to 300sec subs. All 26 were good, and the result even contains some visible nebulosity, despite of the non optimal conditions. #Astrophotography #AM5N

My first target was the globular cluster M15. I played it safe and used 30sec subs. Had to throw away a lot of them due to clouds… #Astrophotography #AM5N

To finish the night I shot a single 5 minutes frame of the Horsehead nebula. It came up pretty well and showed the mount tracking and guiding are really good. #astrophotography

A single shot, very tenuous image of the horsehead nebula.

And this was the last stack I captured. The fireworks galaxy. #astrophotography

So I’ve got an AM5N mount and yesterday I went to the field to do some testing… The first attempt was… suboptimal. I screwed the autoguide config and had to throw most of the subs I got. This is the result, M81 under really bad seeing and strong atmospheric distortion… #Astrophotography

M81 galaxy, with really bad atmospheric chromatic aberration

Una galaxia molt xula… I amb una supernova activa. No se si encara és fotografiable avui. Aquesta foto és del 8 de setembre.

NGC7331 amb una supernova marcada. La foto està feta el dia 8 de setembre amb un telescopi Vespera 3.

That’s Mourinho for you. In his first period in RM he was continuously doing this. Oh, and other things too…

And, to finish, a little love for our close(r) neighbours: Saturn thru the Celestron 6SE scope and the ASI585 camera, processed with PiPP and stacked in autosakkert. The seeing conditions were quite bad despite dark skies. #saturn

M27 aka Dumbbell nebula. I finally was able to use my EQM35 mount with my Celestron 6SE tube, with a f/6.3 reducer. That thanks to an ASI585MC-Air smart camera taking control of the mount in EQMod mode. Still not satisfied, the tracking was not good and the autoguider was overworked.

IC1848 aka Soul Nebula. Also a multi night effort, for 3 hours and 15 minutes of exposure. #smarttelescope

The Andromeda Galaxy. This is the result of a multi night capture with a Vespera 3 smart scope, for a total of 2 hours 14 minutes (and counting). Heavily processed in Siril and finished in Lightroom. Maybe I pulled the magentas too far to show the star nurseries… #smarttelescope

Our home galaxy! Taken with my Canon 80D and a Tokina 11-18 wide angle lens. 30 sec exposure, without any kind of tracking and very minimal editing. Have to say the sky was awesome to the point of having goosebumps. #milkyway

Just the moon, last night, immediately after it started to rise. It was very low over the horizon, with a reddish tint the camera failed to get, and a very nasty atmospheric distortion. Celestron C6 + Canon 80D #astrophotography #moon

Given cultural proximity, I'd suggest the British Ordinance Survey.

California Nebula (NGC1499). Taken using a Vespera 3 scope from my balcony (Bortle 8). 1507 x 10 sec along two nights. DB filter. Stacked by the scope and processed in the Singularity app. I had to crop the top right corner due to parasite light. #astrophotography #smarttelescope

Be amazed. This is the Cygnus loop, aka Veil Nebula. It’s in Cygnus, so the scope was pointing to the Milky Way disc. The pic was taken from my balcony, in a Bortle 8 zone (= really bad light pollution). In a blacker sky there would be more stars.

The same object, taken with a Vespera III (50 mm quadruplet). I dimmed a little bit the stars in postprocessing.

Now that you mention the eclipse again… I have a question for an astronomer. Do these structures have a name or are they just protuberances seen edge-wise?

What about this? It is a photography of an astronomical object (the heart nebula), that you CANNOT see with your own eyes even looking thru a telescope (apart from an almost imperceptible haze), it is a ‘software trick’ that allows to add up many minutes of observation to form a visible image.
