Camera and lenses

The weather is very bad in Hong Kong, together with the air pollution, even that I've been trying to do solar astronomy, the time for astronomy has remain relatively low.

Therefore, I've started to switch some of my hobby money to photography, I still got a few prime lenses so that they could be used for astrophotography as well.

I wonder when can I test my Lumenera...

Hello Oldfield, this is James Kevin Ty from Manila, Philippines. I would like to ask you regarding your experience of using your Canon 100-400mm f/5.6 IS zoom on deep sky astrophotography. Hows the CA, negligible? Im having a hard time deciding the buy my first L series lens for general use and astrophotography. Im deciding whether it is a good choice on the 100-400mm on deep sky objects as I have ordered a Sky Memo for my portable use and of course lugging along the TV-101 refractor will not be portable :( I finalizing on the following- Canon EF 400mm F/5.6 prime lens, Canon 100-400mm f/3.5-5.6 IS zoom and William Optics Megrez 72FD. But since I want to have a universal but good quality lens. Think I will be making a right decision getting the EF 100-400mm f/5.6 L with my 500D? I bought the Sky Memo also bec Im starting to invest on a portable setup for me to bring along to Australia 2012 eclipse as well as image the southern skies there. Your opinion is greatly appreciated.

If versatility is your first priority, go for a 100-400mm but if astrophotography is your prime concern, go for a 400mm prime.

DO you like your 100-400mm IS lens? Will you buy the 400mm 5.6 in place of it just in case?

Lastly, if you were to choose to buy between ther Canon 400mm 5.6L and a William Optics Megrez 72FD. which do you think you will get?

I love that 100-400mm for its great quality, but sad to say, I didn't get any chance to use it on deep sky objects yet. I only tried to use it on the planets!

The 400mm prime is great enough in terms of quality for deep sky imaging. Unless the Megrez is way cheaper, I don't see any reason to choose it over the 400mm prime.
