With the contrast that high, you can see Cygnus more clearly. It should also make out the core visible as well....

I am off tonight to hopefully capture the comet, while out I'll see if can get the core.

I was joshing with you about the moon.... i know your not that daft!!

But.... your best chances are still when there is a new moon. Even tho the moon is below the horizon, it is still throwing of a huge amount of light. As you know, wide angle lenses are light hoovers. With a scope I am a lot more focused on a smaller area. So I will not get as much light in.

As for the core, yes it is there but it kind of isn't. During October its rapidly starting to fade. I've found through experience Aug/Sept are best.

Another good app is APT DC. It gives you all the timings for twilight, sunset, moon phase and strength. See image below.

Link to APT DC




DSD Time is your shooting time. It is the time between astro twilight end, and moon rise. Unless you have a narrow barrow band filter. As the moon fades this will lengthen.

Repeat after me....

I will not.....

Go out.....

And try.....

Astrophotography....

While....

The Moon....

Is out!!!



Unless you have a dual narrow band filter!! Which to fit that lens will cost an arm, a leg, and your left testicle!

The moon is at about 70% brightness. It'll just wash everything out.

Also at present the core isn't visible. August/September is the best time to catch it. Have a look at Photopills. It's a payware app for a smart phone, but it is really usefull for planning core shots. It tells and shows you when the core is visible, as well as telling you the best times to shoot it.

This is my loved, but never used 10-17mm Fisheye. I have been umming and ahhhing for ages over this, but I now tend to favour ultra wide angle lenses. So now it's time to give it a new home.

If you like experimenting, then this is the lens for you!

Comes with a neoprene pouch.

£180 in RM SD

Payment via bank transfer.

We have all done it!!!

I once went to a band practice with an empty guitar case!

Loving these.... especially No5!!

But if I may make a sugestion.... The white border on the first one makes it very stark to my eyes. Maybe a darker or no border will give it more impact?

I don't drink.... so I think that answers your question!

@Flan - I know about the Irix lens, but sadly I can't afford one at present. The Sigma was just over £100. Next year hopefully I want to get a K1. If it happens all the Canon kit will go, mainly to fund a couple of used lenses for it. The Irix will be one of those lenses.

@davidwozhere - As Steve says... it's the nature of ultra wide angles. I have a Sigma 10-20mm for my K3. That has a very pronounced effect on images at 10mm.

@Lubbyman - as ever..... you get thinking laterally!

1. Yes I can very much use this lens, as I love the effect. So it stays in my creative tool box!

2. At just over a hundred quid.... it is acceptable quality, and I am happy with the outcome. No matter how much a lens of this extreme nature costs, there is always gonna be a compromise (with the exception of Fisheyes).

Guys.....

I have just bought a Sigma EX DG 12-24mm HSM 4.5-5.6 Ultra Wide Angle Lens for my Canon 5D MkII, and at first I thought it was crap. Then I figured out why.... the AF is crap on this lens. It just isn't accurate, MF does the job!

I am undecided whether or not to keep hold of it...

I value the opinion of you guys.... so please.... give me your thoughts!

One other thing.... has anyone used one the Walimex 14mm 2.8 Lens?

Thank you,
Ian

Fantastic selection!! Well spotted
