Re: Plato albedo features 4

I've been trying to compare these to images I took years ago, but no luck so far! I guess the streaks are only visible at high Sun? And maybe I avoided imaging at that time.

Any guess as to magnitude?

Re: Plato Crater albedo features

The image is still very small, even when doubled up. Can you add a larger version?

I guess a red filter would steady the view a little as long wavelengths are less sensitive to atmospheric seeing?

Re: Jupiter and its five moons

I do have a good number of Tak eyepieces - I knew the local dealer years ago and he wasn't too far from where I lived. So, he got my money :)

I do like Televue Panoptics and I have a 2" 41mm that I use as a finder eyepiece!

Re: The Sun Today

Sat Nov 27th 2021, 1515UT. Average seeing, but very windy.

Two groups south, one with 5 spots, one with 7.

I suspect I missed some smaller spots as the wind was rocking the projection screen.

Re: Jupiter and its five moons

I can't remember for sure, but I was probably using an LE7.5 and an LE5, which give magnifications of X71 and X106.

The FOA60 is very portable (even for me) and gives extremely sharp views.

Re: ISS Pass through a Dob

1. Grazing the top of Saturn and Jupiter, passing Saturn at 16:50, maximum elevation 21 degrees. 2. HIgh above the two planets, above Saturn at 18:27, maximum elevation 44 degrees. For me, here in Devon, the 16:50 pass is at 40°. And the 18:27 one at 83°. Max altitude for this second pass is at 18:...

Not sure what to record today - one group of 8 spots or two groups of 6 and 2?

Re: ISS Pass through a Dob

And the good news is that early evening passes are continuing right into December, at least until the 4th. Checked Heavens Above a few minutes ago, and, bingo!, there was a pass right overhead. Grabbed red torch and rushed to conservatory - cloudy, natch. Another pass just after 7 pm, but not nearl...

Re: ISS Pass through a Dob

Are you using a 2" eyepiece?

You must have very smooth bearings to be able to track the ISS at the speed it moves.

Re: The Sun Today

Wed Nov 24th 2021, 1525UT. Average seeing. There was a brief clear spell late on, as the Sun was heading rapidly towards the horizon. But the seeing wasn't too bad. All I could see was one group in the south-east with 5 spots. Of the two other groups that have been heading towards the west limb ther...

Re: Sirius into daylight - historical record

I think it was me who originally asked the question.

I tried to spot it one March evening before the Sun had set. I got it eight minutes before sunset with 8x50s, but couldn't get it naked-eye until eight minutes after sunset. It was slightly hazy, so it might be doable on a very clear day.

Re: Large dobsonians

All watched, thanks Jeff.

As you say, the Jupiter image was a bit grainy, but I guess that's because they just stuck a DSLR on the back. It might have been better with the old Mark-I eyeball!

I have the magazine, but I haven't got around to reading it yet! I will do so ASAP. Thanks.
