Finally! After a month of clouds, a short break in the cloud cover for #comet C/2025 A6 #Lemmon. I could make 6 x 15s exposure with Nikon Z6 and 85mm 1.8. Comet easy visible with naked eye, and over 10 degrees tail in binoculars. Then again... clouds.

Here's a quick pass I made at some data for the "Ghost of Cassiopeia". This is just shy of 40 hours of data and damn that star is BRIGHT. I'm going to spend some more time with it and see if I can't tease out some more contrast in some places but it was a fun one.

Comet Lemmon taken last night, 24 Oct.
Some fantastic detail in the gas tail, which has changed a lot in only the last few days.
Mono image only, due to cloud coming in before I could capture RGB data.
22 x 45 sec exposures. Esprit 100 scope. 2600MM camera

Reprocessed my comet Lemmon data to show it against the fixed star background.
Taken with my 100mm refractor at 550mm focal length, and mono ASI2600 camera.
I took some RGB data too, but not sure if I can use this to give a colour image

I tried my best to capture an L-RGB image of comet C/2025 A6 Lemmon using a monochrome cam. It's feasable, but it's not as nice and starightforward as with a color cam because Comets move fast!!!!! #astrophotography.

![C/2025 A6 (Lemmon) is a non-periodic comet discovered by the Mount Lemmon Survey in images obtained on 3 January 2025. It has an inbound orbital period of about 1,350 years and will pass perihelion on 8 November 2025 when it will be 0.53 AU (79 million km; 49 million mi) from the Sun. This perihelion passage will reduce the orbital period to about 1,150 years. It makes its closest approach to Earth on 21 October 2025 and may be visible to the naked eye 42 degrees from the Sun after sunset. As of 12 October 2025, the comet is about apparent magnitude 5.6,[6] and is visible in binoculars about 15 degrees (approximately one and a half fists) below the cup of the Big Dipper. It is currently about 2 degrees southwest of the star Psi Ursae Majoris.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:dksfsl7lygnhrmfxsxcznf3u/bafkreidp6cmbwr464kygmuzq2f72k6azorsjbssfjpfa5mldh22byia5su@jpeg)

I captured Comet Lemmon early October 7, 2025. Using my 300mm Ceravolo telescope and CCD camera. About 30 minutes of total exposures using LRGB filters. The tail is much longer than shown in this 1 degree field of view.

My first try for Saturn since last year. It took a while to set up my scope for this. I'm feeling very rusty!
The rings are narrowing with their South face tilted towards us; they'll be nearly edge on around the end of November.
It feels good to be doing planetary imaging again 🙂

There's something about a crescent moon that rivals other phases. They're so dramatic. I rendered this one as a "mineral moon," revealing its mineral deposit colors.
