ah right thanks, hadnt realised astro photography means long exposures but that makes a lot of sense. Yeah I could see how that could be annoying running a five minute exposure and then you've satellites flying through the picture. I presume that when the image is stacked the satellites them come out as long streaks as they pass through the frame?

Also is Musks promise to paint them black going to make any difference to the problem or is it all just window dressing?

There was only a few sent up with the last batch of starlinks that had anti reflective coating on them. Remains to be seen (pun intended) but at least it is being recognised an issue.

That's it exactly, usually when stacking images they are shorter exposures though so if any are in frame they'd look like dashed lines, stacking is also depended on the frame rate of video or in the case of taken images the pause between exposures. They would not be equally spread out dashes because the majority of the images taken could be discarded.

Thanks sounds very interesting. Ive always enjoyed the astro photography images that broadsheet.ie feature every few days, dont know much about whats in them but some great images get posted.

Starlink 9 launched this morning and it looks like clear skies for the pass tomorrow morning @4.All of the sats have visors now but may not be deployed straight away.https://www.heavens-above.com/StarlinkLaunchPasses.aspx?lat=52.4412&lng=-7.8748&loc=Unnamed&alt=0&tz=GMT

Starlink is an amazing sight for the first week after launch but it needs to pass close to ireland at the correct time and we need clear skies.I'v been watching for over a year now and have only seen the after launch flyover twice.Its like a huge firework crossing the sky 24 hours after launch.
Next launch is next week 28th so if all 3 conditions line up, it is well worth seeing.

Its looking good if the launch goes ahead on wednesday morning.Its passing Ireland 80 mins after launch and thursday morning too,possibly passing all weekend

Anyone know where I get detailed pass information for Starlink launch 28 later tonight?

Heavens Above and Stellarium don't seem to show up anything...

From a link I saw on twitter:

You can't really see these anymore I don't think

Second stage should be flying above in around 10 minutes.
As for the starlink the recent launches have been visable recently as they are tightly packed together so very noticeboard.

Flying Abruptly · 26-05-2021 8:17pm

Thanks for the link.

I was able to clearly see the last lot a day after the previous launch on the 16th May as the typical train of lights in the sky. Think there was also a thread about it here at the time.

This site I find very good.
Tonight at 11.10 and 11.23 should be visible if you have a clear sky.

I assume its not possible to see if its not dark outside yet?

Its difficult. Very.
I think I have only ever seen one during daylight hours.

It is unusually clear here at the moment and I went out just in case but saw nothing. I have only every seen a launch of a shuttle over Ireland at night many years ago.

ISS is amazing to see in summer evenings before it's totally dark. Too tired to stay up for this later

FFVII · 26-05-2021 11:29pm

Nothing to see on that pass anyway

FFVII · 26-05-2021 11:45pm

ISS looking well though. Something flew past (meteor) while i was waiting for it aswell

Flying Abruptly · 27-05-2021 7:21am

I didn't see them either, the Moon was far too bright and I could only make out the brightest stars/constellations.

upupup · 27-05-2021 9:52am

The new satellites have an anti reflective coating which is a good thing for astronomy.They are only half as bright now as they were and the best view is in the first few days after launch when they are still low.
The pass last night was 2 weeks old so too late to see anything spectacular or anything at all

When do any of the databases usually start showing the pass data for recent launches? The L28 table for last nights launch is blank on heavens above.
Because the Flight no. and Mission no. (L) are different makes finding information confusing as different sites refer to different numbers.

Heavens-above is the best site for info.last nights launch is blank on the site because it is not passing ireland at night.25th june is the next pass at night.
This link shows all the starlink sats and if you selects L28 from the drop down menu you can see its orbit

Ah ok, thats makes more sense, thanks.

I had looked at the 3D display earlier but there was just a place holder for L28. It looks like it has updated now with the individual satellite numbers and IDs.
