Selling things

I'm recently selling my Canon 400mm F5.6L and my modified 350D.

A friend is already interested in the 400mm, dunno if anyone would be interested in the 350D....

The 400mm is an excellent lens for deepsky photography. The stars are all neat and tight and round at the corners, at least on an APS-C size sensor. It is ultra light and portable, it is even smaller than my FS60C. I hate to let it go but i don't have any serious use for it after the solar eclipse. My Sky90 has the same focal length but almost one stop faster, and it can be used with a 2" LPS, while the 400 cannot.

I'm not complaining anything about my 350D, its just I am getting a bit lazy and I want liveview with DSLR... Also its autofocus is not working really well for daily use, but i'm sure its the problem of all 350Ds but not only mine.


People are asking if i want to sell my 135 F2... you bet, haha.

One big heck of a project...

I have no confidence in whether much of the red nebulosity is real...

Film is going to end...for me?

After I had my 350D modified in June, the quality and quantity of the images produced this year already have far surpassed those I've done using film in the past 5 years.

OH MY GOD...

Anyone who has any sense would not try this object (IC2118 aka Witchhead Nebula) under the sky in Hong Kong.

As I'm a person with some (though limited) sense, I actually did not try it. It is just a mere coincidence that I happened to record this nebula down as part of a 4x2 mosaic project.

What is suprising is, it is not only a detection, but a clear portrait of the ultra faint nebula.

Oh my god...

2 frames mosaic, 1 hour each.

Background a bit uneven, but not mood to have a delicated correction.

Have been sleeping late or haven't slept for consecutive 3 nights...

Sigh.... I forgot to change the battery when shooting my last frame.

3 frames mosaic

I have learnt so much these two weeks shooting from my home in downtown Hong Kong. Although some encouraging results are obtained, more invaluable lessons are taken.

Firstly, I now FULLY appreciate the value of dark and transparent skies. I really couldn't imagine how well these photos can be if they are shot under a dark and clear sky. I compared the photos I took this week and the ones taken indoors last week. The interesting thing is the ones taken last week, despite taken indoors and have much less exposure, are actually clearer, deeper, and more colourful than what was taken this week. This is solely due to the difference in transparency.

Secondly, despite the seemly good results, I actually have less motivation in shooting from my roof (unless the sky is REALLY transparent) after these 2 rounds. It is because I am now very much aware of the limits of this kind of imaging.

Thirdly, I will not use ISO200 on my 350D again...

Finally, the fact that I finished some mosaics despite under these harsh conditions really encourages me to do it in the fields.
