thanks guys.
I used a cheap film filter that I bought years ago for my 8" telescope. It fits the telescope nicely and I was able to just hold it in front of my lens.

EDIT: so that it's clear, when I said film filter, it's something that comes in a large sheet, a film so to speak, which I ordered and cut to fit the 8" opening of my telescope. I actually attached it to a flat and square USPS box and cut out the right size hole... it's complicated :)

I understood what you were saying Gabe. A few of my friends have
large telescopes. One has a relector that I think is 16 inchs across
and needs several people to move.

Was the film anything like this http://www.astro-physics.com …ries/solar_acc/​astrosolar (external link)

I noticed it has a rating of ND 3.8 and ND 5.0 depending upon which
version you use. Or 13 and 16 F stops. I wonder if the Lee Big stopper
would be enough at 10 F stops. Or maybe stack a pair of them.
The only think I don't know if it filters out enough ultra violet to be
safe looking thru at the sun.

The sun spots on the surface are actually more interesting than the
planet is, to me.

Thank you guys.
Kenji, the lens is great, however, I'm also getting much better at preparing for my shots, building stuff for the birds, shooting with good lighting (the Sun in this case :) ), using a blind, etc.

If I had my old 150-500 OS, or my old 100-400L, these shots would have been very similar, maybe a little worse. But preparations are almost as critical as having a good lens.

EDIT: AND I got better at processing too, and so did the software ;)

You have excelent work flow. From initial preperation, pacients taking
them, right thru to the post processing. Please keep it up and I enjoy
reading your posts on how you are doing it, just as much as the final
products.

And I'm a sucker for birds. My Cockatiels and Budgies can attest to the fact :-P

It's not the UV you need to worry about (the glass in your lens is likely to absorb most of that) but the IR. Although I've not tried the Big Stopper I have tried other high-density ND filters and found that they all let through more IR than visible, a lot more in some cases. My 10-stop Heliopan is only around 5 or 6 stops on my IR camera.

And it's the IR that does the real damage to sensors and retinas.

Evan,
To be onest, I don't remember what film it was, it could have been Baader. I know it was an inexpensive option and works great. I haven't used it on my telescope for a long time though. (But it came in handy for Venus)

Gabe,what software were you usiing before?

I've been using Photoshop for a long time, even before I got into photography (at my "real" job). But for RAW files I used DPP at least as often in the past than Adobe Camera Raw. That was an older version of ACR and its noise reduction wasn't as good as today's version.
At that time I did not have a winning workflow.
Nowadays I am able to salvage less than perfect shots in ACR and make them look nice at 1000 pixel size. (But I also print them occasionally and they look good in print too.)

True enough, I've been shooting birds with my 70-200 f/4L IS and also with a cheapo Nikon 55-300 on a D3100, I wont post them in here (since it would be off topic) but i think i've been doing pretty darn good with either combo considering...

A 1.4x Kenko Tcon is on its way for my 70-200 now because i do wish i had just a bit more reach and its the most affordable option for me at the moment however :)

Yes I built it :) Looks kinda like a grave with a shallow tub on top which is lined with plastic. :) The actual water level is probably 8-10 inches above ground level.

I'll take a picture of it later.

What type of tripod head would you recommend for this lens. Will a good ballhead do the job or is a sidekick or gimbal needed? I am intending to replace my ancient and useless tripod in the near future.

A good ballhead will do the job, but a side kick will make it A LOT smoother. I've used a 300 f/2.8 and a 500 f/4 on a sidekick and both worked seamlessly. Getting the lens "off the ball" generally provides for better control and smoother operation in my experience. Especially for bigger glass. The key is rotating the lens into portrait orientation. It just seems to be easier with a sidekick/gimbal than with the ballhead.

Since the 120-300 is bigger than the 300, I'd assume it would be VERY happy on a sidekick. I think a gimbal might be on the verge of overkill.

I use a Gitzo Fluide head, it's very smooth and balanced. It's a joy to use with my Siggi
