Unknown comet / object in Veil Nebula - NGC6960 (near 52 Cygni)

!UPDATE!
It turns out that the "comet" might just be a strange reflection of the star..unfortunately :(
!UPDATE

So, much to my surprise, when starting to edit the images in PixInsight for a revision of the previous image of the Western Veil, i got myself a comet on camera :) Also made an animated gif. I think it's a comet due to the greenish colour..however i cannot so far identify it.

Veil Nebula (NGC 6960 - Western veil)

The image below consists only of 10 subframes x 300seconds but were taken at a site with very dark skies.
Imaging scope was GSO Ritchey Chretien 8 inch and main camera was QHY8L.
Also 10 darks/10flats/100bias were used.
Stacked with DSS and processed only in Photoshop.. can't wait to process it in PixInsight :)

WIKI:
"The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky.
The nebula was discovered on 1784 September 5 by William Herschel.

There are three main visual components:

The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", "Finger of God",[5] or "Filamentary Nebula"[5]) near the foreground star 52 Cygni;
The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 and IC 1340; and
Pickering's Triangle (or Pickering's Triangular Wisp), brightest at the north central edge of the loop, but visible in photographs continuing toward the central area of the loop."

M101 Pinwheel - 05.07.2014


This is the second attempt with the GSO RC8" and the QHY8L, this time on M101.
There are 18 lights x 300s , 10 darkds, 20 flats and 100 bias.
Acquisition with EzCAP, guiding with PHD, all image registration/calibration and editing was done in PixInsight - great tool btw :)
The first image was also been streched again in PS, so the processing still continues until i reach a final image that i will be happy with.

M27 with 8" RC

Hello again,

Below is a set of 10 subexposures of 240seconds of the Dumbbell Nebula, taken with my newest addition, the GSO Ritchey-Chretien 8inch scope and the QHY8L.
Darks and flats were used, stacked with DSS, and very quick PS editing (just levels, curves and some denoise).
I am thinking of getting the PixInsight software since the trial is over and it is 10 times as good as Photoshop..



Good night and clear skies,
Andrei
