I told Lorna to remember her old Dad when she sees the next one in 2080!!

2040 shouldn't be too bad, although it'll be at the wrong end of the day: 6am ish 30-31/10/2040 should be viewable, although only an unimpressive 1.1 degrees minimum separation. But it will have the benefit of a quite close-by Mercury. You'll still be a spring chicken. It's in my diary anyway.

Managed to catch this tonight 19-12-2020 @ 16:28UT, clouds parted long enough a few stills, and a couple of videos, not holding out much hope on those but at least it is something. SW 200P and Ca

I had packed the little Carton 60mm in the car ready to drive up a nearby lane for a view.. ..I was cooking supper and took some peelings to the compost bin at the end of our (slightly sloping) g

Dronnie eh? I'm a Chesterfield (Duckmanton, nr Bolsover) lad originally although in Berlin now! I would much prefer your Bortle 5 skies 😉

I would imagine the sky from Duckmanton would not be too bad, especially as the nearby Coalite plant has now gone, on good nights I usually get a SQM reading of 19.75 mag/arc sec2, which is consistent with Bortle 5

My 8mm ep is around .32 degree fov. The planets separation was roughly half this (or a little over). I make it about 9 arc min separation last night.

That is what Cartes du Ciel indicated as well.

My zoom at 7.2mm plus the 2.25x barlow was giving 281x in my Tak 100mm F/9 and I reckon the AfoV of the zoom plus barlow at that focal length is around 55 degrees and the true field of about .20 degree. Result: both planets easily fitted in the field of view :smiley:

That sort of power was not doing either planet, and especially Jupiter, any favours though, with them being just on the tree line here so throttling back to 150x -180x gave crisper views and enabled a little Jovian and Saturnian detail to be picked up.

It was seeing both these fabulous worlds and some of their moons in the same high power view that was the fascination though :icon_biggrin:

Looking at the forecasts, the next 3 days look pretty hopeless but Christmas Eve looks hopeful with the planets still just 20 arc minutes apart, If I can get a "pass" from the boss that is ! :rolleyes2:

Yes it was a sight seeing both together. I was surprised to get such a good view at x187 considering how low they were. The next few nights are a no go for me, regardless of weather. Christmas Eve will be OK if the weather is good, and I get my chores done!

NB Second image added which has been RGB aligned, seems slightly better.

Today and this evening have been a total washout here as predicted :clouds2:

Very glad that we been able to observe the pair quite a few times as they approached each other.

Just as well that this is an event that unfolds over a period of time - more chances for us astronomers under highly variable winter skies to get some views in :icon_biggrin:

I’ll post on the heads-up forum, but I’ve just seen it pointed out that Mercury will join the party in January. Lovely grouping on 9th, low down so I suspect naked eye or binos best for this, although they will fit into a widefield scope view quite easily.

Thanks Stu. I don't recall having seen 3 planets in a scope field of view before :icon_scratch:

Nor do I John so it should be worth a go, though I suspect binos will be the better option. Looks like about a 3.5 or 4 degree field would make for a comfy fit, so your Vixen or my Genesis will be ideal.

Enjoyed good views on 19th & 20th through my little 70mm. a gap in the skyline in just the right place from the back garden till about 6pm.

I knew viewing on  the 21st was an outside chance from the weather forcast & sadly it was  all too correct  for my location.

Such is UK astronomy.....a 200mile trip to Cornwall in '99 was similarly disappointing.

Did anyone in UK manage a glimpse on 21st? Please tell if you did.

But still,overall very pleased with the views on 19th & 20th.

& UK weather breeds a certain type of dedication in the nations'  Astronomers??

I recommend a fast telescope as the only way to see the conjunction properly.  It needs to be up, cool and focussed in less than two minutes between sunset and cloud gaps.

John

Not actually true🙂.

I got great views of the conjunction in the past week with both 8x32 binoculars and a 6Omm F11.8 scope😉.

Sorry if I misled you.  It was a pun on the weather. 😀

Yes, Ducky is surrounded by quite a lot of farmland still, so the main LP comes from the village itself which is not too bad, and the M1 and commercial park where the pit used to be. My stepdad does have a cheapish frac but not sure how much use he gets out of it.  

I have only had my gear out there once some years ago. We went out to Clumber Park and found a great spot out of of the way and sheilded from local LP, had an excellent night's viewing. Would love to do that again!
