Received: 23 December 2021 at 03:15 JST

 

Hi all,

Here is a previously unprocessed set of data taken near opposition earlier this year. This set was taken under excellent seeing using the 50cm telescope on La Palma (since sadly lost in the eruption :-(

Many very fine details are visible across the planet, and i think this must be among the most detailed images ever produced of the planet from a non professional size telescope. Its certainly beyond anything produced from 35-40cm aperture telescopes. It actually compares quite well with the images we produced at Pic du Midi in 2017.

 

Further, this image is only 5 x 60 sec captures using the colour ASI462MC camera. Food for thought!

 

Wishing you all a very Merry Christmas and New Year!

Hi all,

Here is a view of 67P from December 6th. Interesting how the tail morphology looks near identical to images from when the comet last came around several years back.

Hi all,

Here is an image from earlier today. Details are on the image.

Processing this was a headache as the comet is moving quite rapidly.
