Ho dovuto ripostarla per delle migliorie ,rigrazio tutti per le visite e i complimenti che mi avete fatto, è stato un grande scatto unico e raro nel suo genere di sicuro interesse astronomico accompaganto pero' anche da tanta fortuna.!!,dopo tanti giorni di attesa per il maltempo finalmente sono riusito a fotografare questo spettacolo della natura.un speciale ringraziamento va anche al mio caro amico Michele che grazie ai suoi consigli mi ha permesso di fare questa stupenda foto. la sequenza è stata realizzata sulle montagne di Sasso Marconi in provincia di Bologna verso le 19:28 con un attrezzatua EQ5 Canon 7D con un obbiettivo Canon 70-200 f4L IS con una distanza focale di 200mm.

Lorenzo thanks again for your opinion, questionable or not as mine! I gave the photos over to Astral for a thorough check on his great knowledge in the field to people responsible for their own opinion. We will see what will come out .. ! If you want to analyze it too, send me your e-mail I send you without any problems. In fact, I'd like that.! Thanks to all for your feedback.

If this was a trail of distant plane, suppose the sky of Spain (to the west), as it would to be animated by sidereal motion? If one were to stop the chase, the comet would exit the field, and the trail would remain at the same point in the frame. As with tracking activated, the trail should go out after a short time from the field, while the comet is in the center. In reality this jet is always there, for which it is an object external to the earth, in space. We emphasize that the sequence has a duration of about 10 minutes.

It is vibration: look closely at the brightest stars of various photos and you will find the same jets in the same position they are in the nucleus of PanSTARRS.

Yes, I agree that it is vibration from various field stars we see "out" a "project" and similar of similar length. That thing is not animated motion sidereal, is only a rough shooting.

Dear friends amateur, thank you for your consideration of these. but 'believe everything you have said so far I have been fine except the vibrations of a EQ5 mount STABILISSIMA GROUND AS A MASSO CONCRETE WITHOUT WIND, CLICK PROGRAMMED WITH REMOTE IN REMOTE without touching the FRAME EVEN WITH A FINGER WITH A GOAL TO ME is COST 1300 EURO .. PLEASE THIS IS NOT THE PITCH VE. EVERYTHING EXCEPT THE LATTER ..!! IN FACT, IF YOU SEE THE STARS ARE ALL TRUE Crawl?. PUNCTIFORM .. AND NUCLEUS THAT STRANGE ...!!
SORRY BUT I AM a neophyte 'I THINK THAT THERE IS A LIMIT TO EVERYTHING.
Thank you.

X KIARA,
please do not disappoint yourself with these assumptions absurd ..!, I remember that I was photographing with a EQ5 WITH TRACKING SIDERALE and not with a simple tripod otherwise with the cabbage that I had the pinpoint stars with a shot at f4 to 30 sec. Exposure ..!
by Kiara .. on ..!!

I looked to the discussion, the subject is fascinating!

However, Manolito not take it personally, I think Simon has got it right, actually watching the HD version you can see the same effect on some stars :-)

just to clarify (it's a thing that can not escape, I preoperatively by Simone I had not noticed):

(If no vibration, could be a reflection)

@ Manolitop76

I'm sorry to disappoint you, but it is the most obvious explanation (Occam's Razor strikes back :-)) And then, as others have already mentioned, it is absolutely impossible *** *** that any object is moving so fast compared the comet. If anything, a fragment should have been point as the comet, and the stars, however, crawl.

You have no idea how much camera shake in this way I have in my files, often without a plausible explanation. I suggest you check everything in your frame and try again, everything will be better!

Best of luck! :-)
Simone

Thanks to Juza and Simone for your comment, and sorry if the tone is perhaps seemed a bit 'too rough, but' these days I've heard all sorts of even that night there were small earthquakes that struck a resonant equipment .. In fact, the shocks were extended on all 15 shots for a period of 20 minutes ...! I leave to you to do due consideration ... sometimes the imagination has no limits!, however I gave the photos to be analyzed to a great expert in the field we will see what will come out out .. the judges will judge.! and if so how will you say will be 'cmq was a nice comparison with people who share my passion in life there is always more to learn, the only question that remains for me if it be as you say, the wake that creates the object "mysterious" near the core is well you can see in the second sequence,as you explain ..? which is not avvine the mysterious "jets" of the other stars who have evidenziato.Comunque I invite you to go and see the great Peter Rosen what he photographed March 15, posting fragment of the Pan-STARRS will 'also a vibration.? to me it seems so much like mine .. judge for yourself.!

Manolito Hello and thank you for the pictures you have shared in private. You see a blur of all the bright subject.
We must unfortunately conclude that it is as you wrote Simone and confirmed Juza. I suggest you check the setup because it is a big problem sneaky!

Could it be that you forgot active stabilizer? And each pose gave a tap is not always the same?

I can see some pictures in the series is less moved than others, maybe you could save the night by selecting the best and mediating. The picture itself is not bad, moved apart.

Hello,
Lorenzo

Thanks Lawrence for your cooperation, but the focus I've done manually, the IS was off the focus from 3 m to infinity at this point I do not know what could have happened .. ! Anyway I would ask you just to explain the mini tail that creates the mysterious object near the nucleus, especially in the second photo. How can that happen? Thanks Lorenzo.

X KIARA,
please do not disappoint yourself with these assumptions absurd ..!


Assumptions are not absurd, even the most rock-rimmed universe may have trouble moving, it does not matter if you paid 1000 euro or 10,000 euro! It 'a bit' of years I do astrophotography and also follow the experiences of other friends amateur and I've seen all the colors. Do not take it, but if you continue to practice you will find that it is very easy to have moved, vibration and so on.

A greeting!

Clear

Hello Manolito,
many times you may forget the IS on and not realizing it. But even with this off might be that if the goal is faulty you have a moment of "uncertainty" during which the IS is locked in place.

To diagnose the problem you should bet a bright subject (eg. An LED in a dark room), and make shots with the same camera, lens and settings, all on a tripod. Let us know.

Hello,
Lorenzo

I read the comments and newcomer to the field astrophotography, I think there is a lot of envy for those shots taken by Emanuele in those few minutes.
It's not a shake, there is no defect, or a reflection of objective nor a plane, from let's say it was lucky and good, a truly unique series!

Dear Lorenzo, the fact that the lens is defective is beyond dispute is brand new bought very little and tried and strariprovato in all shooting conditions to see if everything was ok and on all fronts, I was successful, you who are between the other a Canonist know the quality that has the "bianchino" F4L IS, then rule it out. reflections do not talk about because it has optical lenses in fluorite, then obviously as you teach me when you make the first night photos and say the first thing to do is remove the stabilizer and autofocus and go immediately remove the focus manual or the sensor goes crazy .. (This is done well before mounting all) but 'I have not answered the question that I have made above, why the' "mysterious object" creates its own wake next to the nucleus? :-/

If all ragionassero like you, service centers canon would not exist. With what they cost their products, have to work, it is impossible to break.
With this logic does not go very far. Think about it.

X grillo62 thanks for the compliments ..! :-P
X Lorenzo, as you say you actually care centers would not exist if your Canon products are not precluded sure .. ;-) You. Only I have tried everything even 10 rounds ago, 'I'll try again to review it all over again! .. , However, a general thanks to all of you who have certainly more experience than me in this fascinating world of astronomy and 'was a very constructive debate for me that will help me in the future ..!: ;-)
Thanks again to all of you ..! :-P

Hello Monolitop76,
I am attaching a picture of the comet C/2011L4 resumed on 21/03/2013 at 19:28 by Inverigo (CO). I have other (all in RAW format) but does not seem to observe any fragment near the nucleus. Perhaps the mysterious object is due to some "problem" experimental (optical tracking, reflections, ...) and the fragmentation of the comet's nucleus. This is coming from someone who works for a well-known Italian laboratory that, not long ago, he had observed neutrinos faster than light ;-)





Greetings and available for any clarification,
David

PS: According to my calculations (fast and approximate) of the given object in the image Manolitop76 would move at about 1580 km / s.
