Hmm .. very interesting, Pete. Amazing what you can achieve with a PST!


I've always had faith in what it could deliver even before I bought
mine. Well, sort of - I went for a second hand one just in case ;-)

Biggest advance for me was getting a large cardboard box to stick my
head, laptop, etc. in when framing, focussing and generally adjusting
the image. You really need a dark environment in which to work. If
there was an electronic remote focuser, that would be fanastic. I
could set the scope up on a computer controlled mount and work
indoors. Alas, there isn't and it's the cardboard box for me.

I've not yet put my PST on a tracking mount, so all (rather feeble)
imaging has been by holding a digicam up to the EP. Mostly I use it
visually.

But I do have a Celestron NexImage and I can piggyback it on my
Nexstar8GPS (have the mounting and balance hardware).. and I have both
Mac and Win laptops. So I do have the basic ingredients -- though not
good looks at the Sun much in the last couple of months (So. Calif, but
near the ocean and we are getting an early June Gloom this year).

Maybe about July, after some travel, I'll give it a go.

That's incredible Pete.

Having solar observed a few times myself, I find it strange that the image
isn't moving. It is very easy to forget that the "small" promimence in
your
image would easily engulf the earth, and that it's constantly moving.

It is quite amazing how much it moves isn't it. I didn're realise the
end result would be quite so dramatic. Apparently, 2 hours later the
prom was completely gone.

You're way too good at this. When are you going to write a how to book?

When I finish sorting out my garden ;-)

I've been wanting to do a movie like that for yonks, using the Uni
heliostat (you may remember it Pete!), but...

- I want to do that movie as close to summer as possible, to maximise
the observation length. That limits me to about 10% of the year around
June 21st.

- We get clear skies in Leicester about 10% of the time

- We get a good prominence about once every 10 days-ish? Another
10%...!

i.e. the chance of getting that movie is less than 1 in a 1000! (Note:
there may be *some* approximations somewhere in that calculation...)
And then it would take me a month to process the images...


Pete's one image webpage with one sentance of explaination hides the
effort required to do that rather well, methinks! It always cheers me
up to know that, even if I can't get that movie, someone can.
Thanks for sharing Pete!

ta,

Das

Thanks for your comments Das. It looks like you've come up with the
equivalent of the Drake Equation for astro imaging. Probablility of
success 0.000001% ;-)

Actually, with the current weather, that's not too far from the truth
