The comet Atlas Y4 is like a "cloud" and comet Atlas Y1 have a brilliant coma! RC Marcon 20" F/4.5
Dr Paolo Candy - Ci.A.O. Cimini Astronomical Observatory - www.hesnet.net/candy

Always a stellar nucleus brighter than fragments, but less total magnitude. A fine developed tail and green coma too.

When I centered the comet in my 20 "telescope, and I took the first test photo, I didn't believe my eyes: there was only a slight oblong spot just blurred! Then I thought it was a weak galaxy, and I tried again to aim with more precision, however it was always the same! When I took a longer pho...

A fine Emerald color comet, with a red tail of dust: the show begins to excite! (a quarted of Moon present and insidious).

1 Hour of exposition (90x40sec) with a Marcon RC 20" at F/4.5 + CDS-5D & Idas NGS Filter.
Emerald green coma with very thin tail, a little longer.

C/2015 V2 (Johnson)

Detailed ion gas jets ramified, very elusive. Not a postcard image beautified (photomontage so dear to the fashion), but with intrinsic scientific value ...

A 30 minute photo with my main telescope: a 20-inch F / 8 Ritchey-Chretien, reduced to F / 4.2. The perspective from the Earth, of comet in its orbit, shows us the slightly curved dust tail along its orbit, and a tail of really tiny, slender and straight ions in the opposite direction to that of the...

Comet C/2014 E2 Jacques shot on 06 August 2014 at 03:30 UT from Ci.A.O. Cimini Astronomical Observatory - Italy with instruments (made in Italy ) Zen Baker-Schmidt 200/600 F/3 on Marcon Fork Mount. ST-10XME CCD 3 min L and 1 min each RGB. No double exposure, no photomontage, no comet/stars stacking...

The tecnique to freeze both the comet and the stars is a distortion in the use of software: innaturally. To obtein more details on comet tail, is necessary to push layer (with Photoshop or others ...) of cyan and/or blue, so tail and dimm stars go that color - see Ligustri pictures here: (http://spa...

The Comet C/2012 Panstarrs K1: close encounter! (02JUN2014 23:00UT)

Marcon Ritchey-Chrétien 20" F/8 at F/2.8 - ST10XME LRGB 1 hour exposure bin 1x1 - Cimini Astronomical Observatory - Italy

Not a lot of manipulations via software (big stars, dimmest stars, bottom, tail, coma ...); photo centered on comet, simple and genuine.
