Ho ripreso la cometa dal balcone di casa a Formia (LT) utilizzando un piccolo rifrattore Tecnosky 60Ed focale 360mm con filtro SV260 e camera ASI533MC Pro su montatura equatoriale EQ3.2 OnStep. Autoguida con 40/170mm + camera ASI224MC. Il tutto gestito da ASIAIR Pro.
Sono 16 scatti da 60s - gain 101

Probably the union (Photoshop) of the comet with the trails of the moved stars (Siril) and the fixed stars (obtained through the DeepSkyStacker stack). The whole Siril process for the comet's stack is not giving an acceptable result. I'll try the trial version of Pixinsight Probabilmente l'unione (Photoshop) della cometa con le scie delle stelle mosse (Siril) e le stelle fisse (ottenute tramite stack di DeepSkyStacker). Il processo intero di Siril per lo stack della cometa è stelle non da un risultato accettabile. Proverò con la versione trial di Pixinsight

Those have nothing to do (I think eh!) with that pattern. I think then it's something related to the various stacks and then put back together. I made a tutorial with 3 methods for pix, if you feel like trying the first one. For the starless version I recommend adding Starnet+ to pixinsight, it's free. https://www.youtube.com/watch?v=VrdCcL8J8x8 The R2 Swan is less exciting than the other! Quelli non c'entrano niente (penso eh !) con quel pattern. Penso allora che sia qualcosa relativo ai vari stack e poi rimessi insieme. Io feci un tutorial con 3 metodi per pix, se hai voglia prova il primo. Per le versione starless ti consiglio di aggiungere a pixinsight Starnet+, è free.
La R2 Swan comunque rispetto all'altra è meno emozionante !

But isn't it better not to use dithering for comets? otherwise the alignment is busted, right? Ma non è meglio non utilizzarlo il dithering per le comete? altrimenti si sballa l'allineamento, no?

Zeppo absolutely must be used, as if it were a normal object. Because anyway after you make two alignments, one for the stars and one for the comet, using its nucleus. What is really imperative is not to exaggerate with the length of the poses because otherwise the core is lengthened already in the single shot. Assolutamente va usato Zeppo, come fosse un oggetto normale. Perché comunque dopo fai due allineamenti, uno per le stelle e uno per la cometa, usando il suo nucleo. Quello che davvero è diciamo imperativo è non esagerare con la lunghezza delle pose perché altrimenti il nucleo viene allungato già nel singolo scatto.
