Great stuff Ken! Glad this is working well

What are you after aluminuim wise? Maybe something I can help you with...

Welcome!

Now, does anyone want to be the UK contact so I can send a big batch of stuff there in one shipment and have you distribute it for the club?

I'm more than happy to do this if you want Stephen

Hi Everyone, Please find attached the solar powerpoint that was used for the presentation. Sorry for the delay in getting it up here, initially wasn't able to upload a powerpoint, but Stephen has altered the forum rules to make it possible. Hope is of interest - it was to our students. Article has n...

That's a brilliant account Kev! Thanks very much for that

No.
The M50 is a 1.0mm pitch.

Dang! I knew it was too good to be true... Oh well! :whistle:

Love these 'postcard' images you do Pedro, then wehn you click on the full size it becomes a poster! brilliant stuff! B)

Ta mate, yeah I agree, on reflection it (mine) is a touch on the dark side. Fun to have a play around on a different image though

Is this achievable by mating up readily available step up / step down rings? Could you use one of these http://www.ebay.co.uk/itm/260776776229?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 on the t-thread end Then depending on whether you want a male or female m50 pitch on the other end either ...

Here's my take on it Kev...

That's so weird Mark, we are so alike it's scary :) It will be a trade in so the garage can have the problem. We've never needed the boot rack, we must travel light as even Eurocamping in France we even had enough space for the PST and many bottles of wine. It's going to break my heart though all t...

OK, be patient with me here, never done a PST mod so trying to get my head around what is needed...

The m50 screws into the black box of the pst and the other end of the adapter is a SCT thread which screws into where?

Do you have a pic of one at all?

I'd prefer a rear adaptor going from M50 to either SCT thread or a T thread.....

So, a m50x1mm to SCT thread... what size is a sct thread?

Frustrating. I hear what you're saying Ken.

What size threads / adapters are required? Where there's a will there's a way, and between us on this forum I reckon we can come up with a solution...

Fantastic shots from Barcelona! I like!

Top stuff as always Stephen! B)

Hi Brad, Sadly I have never been to Montana but I would love too. Montana is my little 10 year old car, but sadly my husband thinks it too old so I think it will be gone by March. Then what, do I need to change my name? http://www.flickr.com/photos/alexandra4/6159116819/in/set-72157628535629359/lig...

Not tried it, however have heard a few people say it's more sensitive in Ha so they get shorter exposure times... You could get shorter exposure times by just removing an ER... (sorry, i'll stop it!)...

[quote] In avistack you can select 'minimum area' in the frame stacking stage and it remove this artefact. Thanks for the tip! I need more of these stacking process tips for sure! Avistack in this situation only stacks the areas that occur in all frames that are being stacked, so your final image m...

Hi Merlin,
I typically have an exposure of around (can't remember exactly) 1/60-70 for SS and when I double stack the PST I go down to 1/25 or 1/19 or thereabouts for surface detail.

Regards
Alexandra

What f-ratio is this at Alexandra?

Mark, at this stage I'm not prepared to dismantle one of the SM60... I was wondering though...could it be my exposures are so affected by the tuning I apply between the double stack filters? I really do spend a lot of time setting each filter and then working them together to get the "best" narrowb...

Yeah, completely agree with Walter - when you look at the orginal and look at the outcome it is very surprising! I should have a bit of time this evening to have a play with this and see what I can get - I did try briefly late last night, though my mind was more geared towards sleeping at that point...

They're beauties Jim! Like then alot!

Lose an ERF on the inner etalon, I reckon you'll get your prom exposures upto more like 1/27s

Well, it's taken me nearly a week of tweaking and twiddling but i can confidently say that with the raw data I get out of avistack, using the smart sharpen method I am getting reults that is equally comparable to that that I get from Registax. I am hoping with a bit more perseverence on this I might...

Brilliant images again Richard!
