Hi

Comet T2 PanSTARRS is still displaying a nice tail as it drifts through Perseus. I captured it last night before moonrise as it passed just east of the open cluster NGC 1528:

Re: I2 Borisov

William McLaughlin
 

Indeed, nicely done. It is getting really faint. I had hoped to be able to try it with our setup at DSNM but with the comet getting lower and fainter and the system being a month  behind it's original planned operational date, that hope has faded along with the comet. I did  manage a "detection level" shot with a very similar system here at home in the Pacific NW but that was basically squeezed between our ever-present winter clouds so there were no skies available for a better attempt.

Re: I2 Borisov

Gregg Ruppel
 

Brian:
It was only faintly visible with 2 minute integrations at f/3.7, so unless there is an outburst soon we may have seen the last of it from the northern hemisphere.

Hi all:

The interstellar comet I2 Borisov is moving further south (in Crater
now) and was difficult to image because of its low altitude and the waxing moon:

Subject: [DarkSkyNewMexico] NGC 6357 - The Lobster Nebula in narrowband

 

Hi,

 

This is an image of NGC 6357, also known as the Lobster Nebula, taken with narrowband filters and processed using the Hubble palette. Although known as the Lobster nebula, the FOV of this image is too small to see the entire nebula. It lies about 8,000 light years away in the constellation Scorpius. This nebula is home to open star cluster Pismis 24, which has some of the most unusually bright and massive stars in the galaxy. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity.

 

Comments and suggestions appreciated.
