Comet C2022 E3 (ZTF) with three tails



When looking more closely at my image of Comet C/2022 E3 (ZTF) I saw a third tail. But I thought this was an artifact created by processing the image. 

Untill today, I never heard about comets having more then 2 tails. I always read that comets have 2 tails, one dust tail and one plasma (ion or gas tail). This morning I read an article on Spaceweather mentioning C/2022 E3 (ZTF) having 3 tails : see this link
So why 3 tails? This phonomenon is an optical illusion weh seeing the comet from Earth. How this happens is explained below (source wikipedia).


As a conclusion, my image of Comet C/2022 E3 (ZTF) has 3 tails, one dust tail, one plasma and one anti tail. Below I added false colors to show more detailed all three tails.

Sunspot AR3190

The huge sunspot AR3190 is about 710MH and visible with the naked eye. Through the thin clouds and with sunglass I was able to see the sunspot.


Sunspot AR3190 has a couple of lightbridges. 
The image was made using TAL200K f/8.5 and ASI290MM. 

Setting : ND3.8 solarfilter, OIII filter and IR/UV filter.
Software : SharpCap 4, AS3!, IMPPG, CS4



Comet C/2022 E3 (ZTF)

 



I waked up at 4h30 to image the comet C/2020 E3 (ZTF). Temperature around -3°C and a layer of 5cm snow. Polar allignement using my guidecamera and sharpcap4. After 3-star allignment I connected with Stellarium and N.I.N.A. When imaging the comet, N.I.N.A. gave an errow which I was not able to fix. As a consequence all pictures made with SharpCap 4.

Setting: TLAPO80/480 f/6 and ASI2600MC
Software: SharpCap, Stellarium, APP, CS4
Lights : 20x45s, 10x60s; Darks 10x45s, 10x60s; Bias 10x; Flats 10x
