Comet Neowise C/2020 F3 with TLAPO80/480 and blue filter


The comet was photographed using my Nikon D7500 and TLAPO80/480 f/6 toghether with a blue filter. DigiCamControl software was used to control my Nikon Camera in order to take exposures beyond 30s.
Setting : ISO640 and 9x60s exposure time. Raw data converted to DNG and stacking using DeepSkyStacker. Editing using CS4.

The ion tail is seen left from the white dust tail. The ion tail and the dust tail are "split" somewhat further away from the comet as seen on the picture. 

Comet Neowise C/2020 F3 Dust and Ion tail



Yesterday Comet Neowise C/2020 F3 was much brighter then the day before. High clouds the day before could be the cause but I'm not sure. 
The comet was photographed using my Nikon D7500 with Nikkor lens 18/200mm. Tracking was done on AZ/EQ6 which made it possible to take long exposures. DigiCamControl software was used to control my Nikon Camera in order to take exposures beyond 30s. 
Setting : ISO400 and 15x60s exposure time. Raw data converted to DNG and stacking using DeepSkyStacker. Editing using CS4 and DeNoise AI.

Comet Neowise C/2020 F3 with Blue Filter

A clear sky was not predicted so I was surprised to a clear sky around 23h00 local time. The comet could be seen with the naked eye but very faint. Less bright then 4 days ago. I had also the impression the tail is getting wider. 


Beside my Nikkor lens 18-200 I used this time my TLAPO 80/480 F6. I experimented using a blue filter to capture the gastail. Not sure if I succeeded but the picture shows a diffuse barrier left from the dusttail.

Comet Neowise C/2020 F3 : Colorcoding Nucleus


Earlier this week I made some pictures of the naked eye comet Neowise C/2020 F3. The nucleus of the comet is estimated to be 5km in diameter. I tried to visualise the nucleus by colorcoding the comet based on brightness of each pixel. The result is a colored picture with the nucleus being black and surrounded by less bright pixels using colors grey, purple, red, orange, yellow, green, cyan and blue.
