Comet C/2014 Q2 Lovejoy & Orion Nebula

Much better shot of Comet C/2014 Q2 Lovejoy (50% size)

Since my last observation of the Comet C/2014 Q2 Lovejoy, I waited for the sky to clear up again so that I can try shooting with a star tracker (iOptron SkyTracker) installed. The opportunity came on the night of January 8. Annoyingly, all the attempts to take long exposure photos failed. I first thought the tracker may be faulty, but later I realized that the image stabilization on the camera lens was negating the tracker's movement.

I vowed to not make the same mistake again, and two days later, I went out to take photos of the comet once more. The southern sky was dark enough to let me barely see the comet with my naked eyes, so my hopes were up. And indeed, I finally got the results I wanted - much improved photos of the comet using the 30-second exposure (longest possible on Canon 450D other than bulb mode) setting. The green glow was now evident, and the center of the comet was shining brightly.

For the reference, the comet had moved to near the constellation of Taurus - the large version of the photo shows the magnitude 5 star 40 Tauri on the far upper left. Also, under the camera settings I used, the darkest stars were around magnitude 12, which is the most sensitive I've gotten out of my astrophotography attempts so far.

A nice photo of Orion Nebula as a bonus (50% size)

After taking the photos of the comet, I felt that it would be nice to point the camera at another object since the tracking setup was already in place. As the sky at my location was especially dark in the east and the south, I decided to take a look at the Orion Nebula inside the Orion constellation, which was in the east, going south.

Alas, due to being out for more than an hour in the below-freezing coldness, the infinity focus of the lens wasn't working quite right anymore and the fog on the lens was getting bad. So I took some measures to mitigate these issues somewhat and was able to salvage several shots before heading home. Luckily, those shots came out looking fine.

Comet Lovejoy does not stand still Stars in the sky slowly move together in the sky due to the Earth's rotation. So the long exposure astrophotography involves using a star tracker to negate this motion. However, objects closer to Earth like the other pl

Orion Nebula as seen by Canon EOS 450D & Tamron 18-270mm lens (100%) I wanted to revisit my thought that the DSLR (Canon EOS 450D) would take better deep-sky photos than a P&S (Canon PowerShot SX50 HS). The latter has a much more powerful zoom lens, so m

Comet C/2014 Q2 Lovejoy is getting dimmer When I last looked at the comet C/2014 Q2 Lovejoy about three weeks ago, it was near its peak apparent brightness due to its proximity - it passed the closest to Earth just 3 days ago and shined at a magnitude of
