Comet imaging is always a bit stressful. For weeks the weather was uncooperative, and then – right before the observing window was about to close – a slightly larger gap in the clouds finally appeared… but even this time it wasn’t much more than that.
The day before, I had my first “attempt.” To be honest, it was hardly that. Still, there was a very brief moment right after sunset when I managed to capture the comet from my backyard, with thin veils of clouds constantly drifting through and a streetlamp nearby.
But the real issue that night was the clouds.
One day later, same location, same time, same target, and similar challenges – but definitely fewer clouds and the chance to photograph the comet for about 45 minutes in sufficiently dark conditions.
When it comes to comets, I like using my Canon mirrorless camera. In the future I’ll probably switch to a cooled color camera; dealing with mono for comets is just too stressful for me.
For the first time, I also picked up a Baader UHC filter, hoping it would help reduce stray light on the sensor when shooting from my suburban garden in exactly these kinds of situations.
A proper test is still ahead, but I’m optimistic that the Baader UHC L contributed to the final result. All things considered, I’m quite happy with the image – it really could have turned out much worse under these conditions.
