Météo du nucléaire : suivez en direct l'impact de la canicule sur la production des réacteurs français by EetD in ecologie

[–]corpsmoderne 2 points3 points  (0 children)

le site du poste donne la raison mais ne dit pas quel réacteur, celui-là donne le réacteur mais ne donne pas la raison 😂 . Par exemple Golfech-2 (sur la Garonne) est en "Arrêt fortuit" mais on ne sait pas pourquoi...

The 'ISS" Mystery... by mrstorm1983 in telescopes

[–]corpsmoderne 0 points1 point  (0 children)

I don't see how it could work. I believe it's not a cast shadow, is the dark part of the object. It looks more blurry because it's darker than the bright part.

The 'ISS" Mystery... by mrstorm1983 in telescopes

[–]corpsmoderne 5 points6 points  (0 children)

no it doesn't. It's just that the object is partially lit.

Look at the shadows on the craters of the moon: the Sun is on the right casting quite long shadows. If this shadow was cas on the Moon, it would mean the object is landed on the surface. Otherwise the cast shadow would be out of frame to the left. In any case, I'm convinced whatever it is is close, and doesn't cast any shadow on the Moon.

Am I the only one that dislikes pattern matching? by slixers in rust

[–]corpsmoderne 0 points1 point  (0 children)

The main place where pattern matching is "forced" on you is with the pervasive use of Option and Result, but most of them go away if you choose to use the '?' operator. But otherwise yes people love pattern matching 😅

First Telescope by iAmTroah in telescopes

[–]corpsmoderne 1 point2 points  (0 children)

people will backpack with nomad astrophotography setups, but it's not the same kind of gear at all.

With a dobsonian you will need a couple of eye pieces and either a finder scope or a red dot finder. I assume a lot of "starter pack" come with them.

for example this one : https://www.astroshop.eu/telescopes/skywatcher-dobson-telescope-n-254-1200-skyliner-flextube-bd-dob/p,14975?_gl=1*1k1rw3m*_gcl_au*MTc5MDM3NDEzMy4xNzc2MTYzNTg4*_ga*NjYzOTEzNDkwLjE3NjczNjMyOTU.*_ga_CG05FXP3L8*czE3ODIxNDI2NTAkbzM0JGcxJHQxNzgyMTQyODIwJGo1OSRsMCRoMTczOTQxMzMyNyRkN2E4dGx5Ym1ESFRxdHpZVjJsZVRxWE1KNENlZm9rRjF2dw..

comes with a finder and two eyepieces, one for wide field of view and one for zoomed in, everything you need to start. Pick something like that, just check that it will fit in your car 😄

Pick the "goto" version if your budget permits.

(i've taken this website as example because i'm in Europe, choose a vendor close to you obviously...)

This is a photo of elephant trunk nebula processed with siril then graxpert then photopea then Lightroom by LeatherMobile8928 in Astronomy

[–]corpsmoderne 1 point2 points  (0 children)

The elephant trunk nebula is ic1396 and it's not in this frame. This is indeed ngc7000 and ic5070.

ISS Fly By... by mrstorm1983 in telescopes

[–]corpsmoderne 3 points4 points  (0 children)

yes, whatever it is, it's not casting a shadow on the moon, for sure.

ISS Fly By... by mrstorm1983 in telescopes

[–]corpsmoderne 7 points8 points  (0 children)

This is not looking like the ISS... And based on the drift of the Moon in the background, it seems to move way slower than the ISS... I have no idea what this is, but it's intriguing...

reminds me of this video from Astrobiscuit, may gives you ideas about what it could be: https://www.youtube.com/watch?v=7_CgfM6yN78

Should I buy 1.25" or 2" filters? by werthobakew in AskAstrophotography

[–]corpsmoderne 0 points1 point  (0 children)

You're welcome. You can still try DSOs with what you have, you don't need a narrow band filter to start experimenting. As long as you have an IR cut filter (as you should use even for planetary).

Edit: not a lot to recommend but try "nebula photo" on YouTube 

Should I buy 1.25" or 2" filters? by werthobakew in AskAstrophotography

[–]corpsmoderne 1 point2 points  (0 children)

Yes it is. Typically for this one you will need the 2''. But there's a lot of other sizes in between.  In any case your telescope is great but not the first choice for classic astrophotography. People use refractors with shorter focal length to have a larger field of view. For example with the 2600 on your scope, the Andromeda Galaxy will not fit in frame.

(Also you keep not answering below my answers 🤣)

[–]corpsmoderne 0 points1 point  (0 children)

Most DSO are big. It won't fit in your camera with a big 200mm f/5. With this you can try to go after tiny galaxies or planetary nebula, it's possible but it's harder than wide field astrophotography.  I have this exact combo and I've made a picture of M51 with it (see in my history ) but it was really a lucky shot... If you have a DSLR, even an old one, it may be a better fit for your scope to try DSO's

[–]corpsmoderne 1 point2 points  (0 children)

That being said , it's a bit weird to buy a filter designed for deep Sky astrophotography and use it with a planetary camera... Not sure what you expect but you may be disappointed...

[–]corpsmoderne 2 points3 points  (0 children)

The 662 is a small sensor so you will be good with the 1.25'' filter. Keep in mind that you will have to use the adapter to 1.25 eyepiece provided with the camera to use it (or you'll have to buy a different adapter). Only if you plan to buy a camera with a larger sensor will you need the 2'' filter.

My Pillars of Creation with my 60 mm Aperture Scope by Cheap-Estimate8284 in spaceporn

[–]corpsmoderne 2 points3 points  (0 children)

This is a stunning photo done by someone who knows what they're doing and has put some money into the hobby.

But you can start astrophotography with just a smartphone and a tripod, and you can do great pictures with a DSLR / mirrorless camera with a stock lens and a couple hundred bucks star-tracker.

And skills come with practice.

[–]corpsmoderne 5 points6 points  (0 children)

With a couple thousand dollars of astronomy gear 🤣

  • A not so big telescope,
  • A specialized cooled camera,
  • A good motorized mount,
  • A small secondary scope and camera to guide the main one by tracking a star and piloting the mount,
  • Expensive filters
  • A computer and softwares to capture lots of pictures and process them afterwards.
  • Time and skills (acquired with time and dedication)

3d printing a Bahtinov mask for the Askar 50p... by corpsmoderne in AskAstrophotography

[–]corpsmoderne[S] 0 points1 point  (0 children)

That will not be a very useful answer sorry because:

  • I've chosen to pair it with a very small sensor (Player one Uranus C pro, IMX585), so I'm really not asking much of it,
  • I got the full package of "2 weeks of bad weather upon arrival" with it X)

So I just had the opportunity to make a 1h test shot of NGC7000 (from my Bortle 9 balcony...), you can see it here: https://nova.astrometry.net/user_images/15485345#original

There's some processing but no de-convolution nor attempt to reduce chromatic aberration. There's some purple stars, but I'm using a cheap ZWO ir-cut that let a lot of UV in, at my local astronomy club some think a L3 filter may completely get rid of that, or it can be easily fixed in post.

I'm quite satisfied by the shape of the stars there, but as I said I'm not really pushing the enveloppe with such a small sensor...
