Hi Folks,
Has been disappearing from this forum for quite a long time.
In the past 10 years, I spent my summer holidays in Australia or New Zealand. Besides sightseeing, doing AP was also one of my focus with my holidays.
Attached please find a photo taken last year in Canberra. Too see more, please visit my webpage at http://www.william-lt-ng.com/Starfield.htm .
This year, I can't go to Australia again but to New Zealand.
I am afraid now of that the wet winter in New Zealand may give me very less chance of getting clear skies for AP.
Love to hear your comments, if any, on my images,
Thanks.

Well I just spent a very pleasant hour looking at the images in your website. Welcome back, and especially to a Pentax 67 user. Jim - the Nightfly and myself are also Pentax oriented - an understatement.
The darks site makes an incredible obvious difference. I was very interested in the 90 lens photos, as I have this lens as well. I like what I see, especially at F4.
The fact that these images are unguided for 60 minutes is very impressive. I would never have believed that this end result would be possible - and Jim has been telling me so, with a good polar alignment using wide field lenses.
Interesting also to compare the Provia 400F images with the Kodak E200. Which film do you prefer - understanding that 400F is not available anymore?
Great images, and I hope that you continue with us here in the Film Forums. We now have a Pentax Trio.

LT,
Very nice images. I would love to expose some film uder those skies, especially with that southerly latitude. I shoot almost to my horizon to get most of Scorpius and Southern Sagittarius. I hope you will post often.
Does your year round residence allow for astrophotography? I am lucky to have dark skies here in the northeast US. Film likes dark skies. Like Nebhunter mentioned we are shooting P67's with various lenses. Igor just aquired a 400 f/4 ED (IF) and he is getting that ready for what I would imagine to be some very interesting images.
Jump back in and hash over methods for processing, etc. Glad to have you back onboard.
Jim

Great image LT,
It's always nice to be able to see what the skies are like from down under. Keep those images coming!

Thanks for looking and the nice comments from all you guys, and sorry for being so late to reply your response to this thread because I am very busy with completing my academic tasks this week.
Ignor,
Yes, the dark site determines all. So sad that we have no dark sky in Hong Kong, and that is why all my star field images were not taken in HK.
The 90mm is a good lens but it is better to shoot at F4 or even slower. At F2.8, there is a little of coma and the stars are not so round at the corner. But I want to shoot more frames. So, let the 90mm be wide open. Next year, and if more stable weather to have, I will try shooting at F4 with this 90mm.
Because I drove everywhere for sightseeing to fulfill my wife's willing in daytime, sometimes even driving upto 700km in a day, I had been exhausted after the drive. So as to have imaging more comfortable, ungiding might be one of my best solution. And thanks for the high quality from Vixen's mount, there is no problem to go for 60 min unguided with the 90mm, even just using the built-in polar scope for polar alignment w/o any star dfrifting applied.
It is also quite difficult for us to find Fuji 400F here. There are Fuji 400x sold but it is less H-alpha sensitive than 400F. Luckily, E200 is still available but its supply is limited. I was quite afraid of that after 2 years, they would be disappearing from the market
I think you may agree that E200S has better red response and smaller grain than 400F. So, for shooting the milky way or the H-alpha rich objects like Eta, NGC 7000 and etc, I would prefer E200. But for comets, galaxies or globs, I may go with 400F.
Personally, I like the color presented by E200.
Jim,
There is no hope for wide field AP with films in Hong Kong. Do you know we have over 7 million people here? But HK is just about 1000 km2? Tall buildings and street lights are everywhere. If you want to have a AP trip to HK, just forget it. But for shopping and eating, that is a perfect place.
So jealous you have a ED400mm F4 lens. I had read a test report by Japanese nmany years before that it outperforms the 100SDUF astrography by Pentax also by a little bit.
In addition, more jealous you have such a nice and dark sky just at your backyard!
Clear skies,
LT

Thank you for sharing your adventures in OZ with us. It's always more interesting when there is a story as well. I also respect your efforts. The long days of driving to fulfill the wishes of others before you can spend time with "our mistress of the night" - the night sky.
