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.

Supernova SN2020jfo in M61 with COAST telescope after 51days

How is it with Supernova SN2020jfo in galaxy M61? I took some pictures of this supernova earlier this year in May. To compare I made some pictures again on July 11 using the COAST telescope in Tenerife. And yes, the supernova is still visible after 51 days as can be seen on the picture below.
