Leo Triplet from Tagaytay
We went to Tagaytay to check out my colleague's farm for any astro potential. Together with Irving, I set-up my gears as night fell. Well, I realized instantly that there's no way I can use the polar scope so I practiced drift alignment. Haze ruled the night as clouds threatened my desire to do imaging. Anyway, I shot some frames of he Leo Triplet between the clouds. I was able to get a total of 50-minute exposure before the DSLR battery went dead. Somehow, the thought of acquiring a long focal length RC scope for small objects entered my mind when I saw how small these galaxies were.

Rosette Nebula for Valentine's Day
I'm not sure if I will be able to add color to my Rosette. I previously imaged this flower in H-alpha and been wanting to blend it with RGB data. But since it already middle of February, Monoceros is already transiting the meridian which means my camera might hit the tripod legs. So, when the group arrived in Buso last Saturday, my yearning to image it was overpowering in spite of the erratic weather. Here I made 21 frames of 3 minutes each and combine it with previous H-alpha image.

Markarian's Chain of Galaxies
I was thinking of a good target when we went to Buso-boso last Saturday night. It is supposed to be a season for galaxy hunting but my gears are not appropriate for capturing small objects. The field of view of my scope is around two and a half degrees which is relatively large so a galaxy will appear puny if I shoot it. But I really wanted to capture galaxies so I chose to shoot a few of them in just one field. This a 22 - frame shot of 180 seconds each duration.

Cone Nebula - Widefield
Somehow, I feel I'm running out of targets for my H-alpha filter. The galaxy season is starting and a clear and moonless sky is what I need for these small and faint objects. At 8pm, Monoceros is almost overhead and I guess its not yet too late for the Cone nebula. Last Friday, I set up my gears at home and started targeting the Cone area. It took me almost an hour to find the cluster area by comparing the eyepiece view with the The Sky planetarium display. I made series of focusing shots then finally at around 8:30 pm I was ready to shoot. I made 30 frames of 4 minutes each until my scope was about to hit the tripod legs. I sleepily dismantled my gears and hurriedly went to sleep. It was not until Sunday afternoon that I started processing the images. I was happy and disappointed at same time. Happy in a way that I captured the Hubble's Variable Nebula in the same field but disappointed that the stars are irregularly shaped. Hmm, need some time for troubleshooting.
