Comet NeoWise

Oneiric 3

This is fascinating and something to look out for over the coming weeks:

https://www.youtube.com/watch?v=todMvN-bnEA

According to the narrator (who runs a great channel) the comet should be visible in the northern sky, and best viewed in the late evening or very early morning.

One of mine from last week. Neowise silhouetted by my friend's son at the top of the Sugar Loaf.

Had a quick look out the back for it here in D11 with binoculars, found it but only to be a smudge now with a slight hue of green. Probably still looks a bit more impressive from a dark location , and possibly then too still in camera long exposures.

Had that same view eight hours later here, by then the comet made a "ten to six" pattern with those two faint stars (faint to naked eye), found a useful procedure for you binocular users to consider, focus on the crescent moon before looking at anything else, you'll find it easier to focus your view as the Moon tells you right away about focus issues.

Moon will be out a bit longer this evening (here, I think most of you are clouded out) and in a few more days, gibbous nearly full moon phase near Jupiter and Saturn.

Thanks for that great tip on the focussing. In fact I could also use that on my camera zoom lens (manual focus only as it’s via a lens adapter) to get proper focus on stars. The lens allows a little variability in infinity focus.

Gave it one last go last night to drive an hour out of Dublin and luckily getting an hour of mostly clear skies. Had to use binoculars but very clear view of Neowise with that. About the same or slightly clearer than the photos I took, like the attached.

Any seasoned amateur astronomer in Ireland will quickly learn that all time limited astronomical events will be clouded out for the entire duration. If its a 5 minute thing, it'll be clouded out for that specific 5 mins. It its an hour thing it'll be clouded out for that hour. One night thing? Cloudy or that night only, week maximum for meteor shower? Cloudy all week. Comet visible for a few weeks?......................Guys, we won't be seeing the sky or Sun till August I am afraid. This comet is a Harbinger of Gloom

I'd say you'd be clutching at straws, especially with cloud cover.

Neowise exactly followed the Murphys Law of Irish Astronomy and Weather.

3 Months of Clear Skies...Best Northern Hemisphere comet in nearly a quarter of a Century arrives...6+ weeks of Cloud during the Comets Naked eye phase.

I jest and exaggerate of course. Many of you had more clear skies and had wonderful naked eye views but for those that did/didn't it was very much hit/miss with a lot of right/wrong place, right/wrong time. The 2 clear sky nights I had at the end of the naked eye phase were a bust when I discovered it was lost in the Dublin Sky Glow from my perspective in Bray and with Binoculars it was lost behind two feckin cranes from my perspective in my Back Yard

Arrgghhh!! (Didn't feel like a walk to the Seafront at 2am in the morning)

Still, it re-sparked my interest in Astronomy and the hobby and I dug out a small portion of my gear that was mothballed and buried a decade ago and was thrilled to find several house and wardrobe moves hadn't wrecked any of it. For example, I bought an old S/H Nexstar 102GT Tripod/Goto (without scope) right when life, health etc got in the way of the hobby for me. For Neowise I dug it out, affixed my Stellarvue F3.7 80mm Finderscope from my 16" GOTO Dob onto the Nexstar, watched a few Youtube Videos about Nexstar GT Star Alignment and the hand control functions etc and ended up getting surprisingly fantastic views of Saturn and Jupiter in such a small scope especially given they are at their lowest altitude in Sagittarius and subject to the worst potential 'Seeing'. Point is, the hardware fiddling/modding (which I always enjoyed nearly as much as the observing) and observing reminded me why I got into the hobby in the first place. I think I'm ready to jump back into the hobby with gusto again.

M.T. Cranium

Is it really an insult to be called a follower of Isaac Newton? I don't feel that insulted actually.

Oriel seemed to have some kind of an issue with the two different frames of reference that modern astronomy has developed. It's worth mentioning what these are, along with the fact that I never thought of myself as a proponent or an enthusiast for either of them.

One frame of reference is equatorial, and deals with "right ascension" as longitude and "declination" as latitude.

The other frame is ecliptic, and uses celestial longitude and latitude. The Sun is (for the purposes of this discussion) always at zero latitude because the ecliptic plane is our orbital plane, and the Sun is the centre of that (it does wobble slightly due to gravitational perturbations, on a very small scale). On June 21st at the summer solstice, the Sun is at its highest declination of the year (23.4 deg N) but at zero deg latitude. The two longitude systems begin at the vernal equinox and I believe they will stay at the 1900 epoch location of it through the centuries, as the Sun's apparent orbital nodes change (it's the earth's orbital nodes actually changing, but against the system being used, it appears that the Sun is shifting).

I know Oriel didn't like that concept and he associated it with Newton, then when he discovered I was more or less following orthodox astronomy in my research, he decided I was part of the Newton problem.

All I can say is, I understand the two systems and tend to use R.A. and dec more than lat-long. That doesn't mean that I am a "proponent" of either system, like you if I want to take part in scientific discussions, I need to understand the frames of reference being used in them. Otherwise we have anarchy where anyone can impose any system they want and discuss things as if other people knew about that system.

The irony is that even my basic interest in astronomy puts me rather at odds with the weather community who are dead set against external drivers in this day and age.

Anyway, today make a note that the earth is in the position that the Sun-Jupiter-Saturn alignment will take up mid-October. We passed Jupiter on the 14th and Saturn on the 20th. In about three months, they will reach the same heliocentric longitude -- the one we are at today. They won't quite appear aligned to us because of parallax, we will be off at right angles to that alignment, and one-fifth of the distance from the Sun compared to Jupiter (one-tenth compared to Saturn). They will appear most closely aligned in December as we swing back around towards their alignment vector which will begin to move away from the Sun as Jupiter overtakes Saturn.

Yes, just in from my daily attempt to find Neowise, only possible with binoculars this evening here, probably can be seen naked-eye in the very darkest rural settings with no high cloud or light pollution (I have a bit of both unfortunately).

Was a good event though.

Buy that man a drink.

Oriel chose to pitch his tent in this forum of late since he was run out of the Astronomy one after being shown to know very little of what he's talking about. He was put to shame by other posters there who paragraph by paragraph debunked each of his ramblings. He came here thinking he'd get an easy ride from people with less understanding of astrophysics and orbital rotations, though that backfired on him too.

Glad to see the back of him.

Popoutman

Here's a processed Neowise from last Saturday night, 24 ten-second exposures, Canon 6d, 50mm lens at f/2.5, ISO set at the standard highest dynamic range for a 6d of ISO1600. Unguided on a driven German equatorial mount.

Stacked in DeepSkyStacker and (attempted) gradient removal in PixInsight.

Not the most aesthetically pleasing, but a nice enough view of both tails, the gas/ion tail being ~20 degrees long up near M81/M82. I know I have banding issues with the processing, I'll figure that out again at some point. Consider it a work in progress..

I figured it would be about the only time I'd get to see it in Irish skies at this brightness, such a pretty sight.

M.T also has a heart bigger than the sun (of which I can personally attest) and this is of far more value in real terms than these supposed accusations you throw his way here. Who really cares about Newton? I mean, really? Whether the earth spins around the sun, or whether the sun spins around the earth, it doesn't really matter in the great scheme of things.

And by the way.. F//K Darwin and everything that he stood for.

Live with the term 'sycophants' as that is what all the insults amount to.

Maybe Darwin was right -

" "The careless, squalid, unaspiring Irishman multiplies like rabbits: the frugal, foreseeing, self-respecting, ambitious Scot, stern in his morality, spiritual in his faith, sagacious and disciplined in his intelligence, passes his best years in struggle and in celibacy, marries late, and leaves few behind him. Given a land originally peopled by a thousand Saxons and a thousand Celts—and in a dozen generations five-sixths of the population would be Celts, but five-sixths of the property, of the power, of the intellect, would belong to the one-sixth of Saxons that remained. In the eternal 'struggle for existence,' it would be the inferior and less favoured race that had prevailed—and prevailed by virtue not of its good qualities but of its faults." Darwin, Descent of Man (Page 174)

Me thinks indeed !, dealing with empirical pimps never was the issue - the observations are there for those who can make sense of them by reasoning things through as individuals instead of playing teacher's pet to a bluffer.

MT is no more or less the same dismal mixture of experimental theorist and celestial sphere enthusiast which constitutes the vandalism Newton visited on astronomy which can be recognised by people of a more discerning and expansive nature -

"That the fixed stars being at rest, the periodic times of the five primary planets, and (whether of the sun about the earth, or) of the earth about the sun, are in the sesquiplicate proportion of their mean distances from the sun.... for the periodic times are the same, and the dimensions of the orbits are the same, whether the sun revolves about the earth, or the earth about the sun." Newton

Only a pure gob****e would imagine an equivalency of " whether of the sun about the earth, or of the earth about the sun... for the periodic times are the same, and the dimensions of the orbits are the same, whether the sun revolves about the earth, or the earth about the sun." Newton

The framework of the great heliocentric astronomers was based on the motion of the Sun directly through the constellations equating to the Earth's motion through the same field of background stars -

https://community.dur.ac.uk/john.lucey/users/sun_ecliptic.gif

"Moreover, we see the other five planets also retrograde at times, and
stationary at either end [of the regression]. And whereas the sun
always advances along its own direct path, they wander in various
ways, straying sometimes to the south and sometimes to the north; that
is why they are called "planets" [wanderers]. Copernicus

I have changed this due to the fact that we now have a satellite tracking with the Earth and free of daily rotation to permit the transition of the stars from left to right of the stationary Sun parallel to the orbital plane due to the orbital motion of the Earth.

https://sol24.net/data/html/SOHO/C3/96H/VIDEO/

The Sun around the Earth was an axiom for daily rotation so no equivalency exists with the Earth around the Sun. The same bluffing of the empirical pimp in this forum is imitating Newton like a hapless monkey wrecking havoc on the noble discipline of astronomy.

Go ahead and post pictures, it is fine as far as I am concerned but at least some try to make the effort to recognise the orbital motion of the Earth, what references are used and how this filters down into Earth sciences like climate.

Either people don't have the confidence or are too lazy to gauge what is in front of them .

I don't suffer mathematical bluffers and especially when I have the imaging power of 21st century satellites to back up the perspectives.

No doubt people scarred by experimental theorists conjuring 'climate change' into existence would have people care, however, to appreciate what the Earth science of climate is requires the dynamics of the Earth in a Sun centred system.

I am entirely content with the insight provided by a 21st century satellite which demonstrates that Earth travels around the Sun so yes, if people do not care then there is nothing I would do about it. In contrast, those who make the slightest effort can catch the glimpse of a bigger picture where they actually look towards the inner solar system and the relationship of all celestial objects in relation to our central stationary star.

There is a saying among genuine astronomers ( which excludes celestial sphere enthusiasts) -

“You cannot teach a man anything; you can only help him find it within himself.”
Galileo

The fact is that some can use 21st century imaging to good effect while others are gladly within a lamentable spectrum of inanity at the centre of their own rotating celestial sphere universe inherited from late 17th century England.

Some get it while others will not, that is the best I can do for contributors to this forum.

Anyone else want to portray themselves as within a spectrum of inanity which restricts the position and motion of the comet to identification alone within a celestial sphere universe ?. Good, then if they can't appreciate the orbital components and structure of the solar system then they have no business dealing with weather and climate on a planetary scale.

Some people can make sense of the appearance of the beehive cluster ( M44 Praesepe) and the change in position from left to right within range of a camera which looks towards the inner solar system and our parent star which inhabits that centre. It expresses motions and positions as they actually exist free of rotation and its rotating celestial sphere of stars as the Earth travels through space and along its orbit.

Spectrum indeed !, you are allowed your identification exercise if that is all you can manage but people of perceptive and intellectual stature can extend beyond that and enjoy the imaging by interpreting what they are seeing.
