Side by side comparison from the two lenses .
Hand held , Image stabilisation on .
With the 500 Reflex that's inbody only , with the 200-600mm that's a combined lens and body I/S .
Not a lot of sun spot activity today compared to a week back .

Well, well ... I never knew the lens hood bit of the 500 came off! What is the thread there? It's not marked on the barrel. I thought the solution was to drop a filter in the slot at the body-end of the lens. Now I inspect it I see that it is an ND x4 filter integrated with the holder. That won't work with the sun, I expect!

The front filter is a standard 82mm filter thread , handy if you want to upgrade the hood for one that does something.
The rear filter should be the clear one , I've never needed the ND4 one myself.
If you haven't got the clear one , you can take the ND one out and cover the hole up with some insulation tape to keep the light and dust out .
That'll keep your shutter speed up .

The ND filter supplied is of no use for photographing the sun , you'd burn your sensor out , or you retina with a dslr !
The solar filters are very different.
To look at them , they look like a peice of tinfoil , rather than dark glass .

Hopefully next Monday we might catch the tail end of the solar eclipse.
If the sky's clear I'm heading up to the pennines to try and get a shot .
I need to be further to the west really , but you never know .
As I'll be focusing on the sun , I'll have the solar filter fitted .

Here I am contemplating a filter for a rather niche opportunity when along comes this:

Photographer Becomes First Person to Capture ISS Crossing the Sun on 35mm Film



(Shot with a Nikon.)

I wonder if Soosie will be up for this

Just don't burn a hole threw the back of the camera !!

The odds of catching that image again are astronomical !

I've seen this shot against the Moon , which also look good . Better really , but fairly common . As said , not so common with film .

Incidentally , you'll notice the size telescope he used to fill the frame and I forgot to mention my images of the Sun above are very heavily cropped .
I haven't taken a shot of the Sun with my reflector telescope , but I've have done the moon and filled the frame .
It was a half moon and filled the frame of an APS-C camera ( a580) so a full moon would fill a full frame sensor or film .

I'll take some shots of the Sun with my telescope at some point , probably on film too , to see how they come out . I doubt I'll get the ISS in it though !

I think this was from when I first bought this telescope about fourteen years ago .
I'd picked it up from the shop on my way over to my friends , calumniated the mirrors , and set it up ready for it to go dark .
I used my Sony and she used her Nikon attached via "T" mount adapters .
She thought the telescope was moving and needed tightening up as the Moon kept dropping out of sight , I explained as the Earths spinning and the Moons moving in orbit , at these magnifications , it does shift some .
Keeping up with the Sun would be awkward without a tracking mount .

A bit more impressive than my 500mm lens shots , 750mm reflector with a 2X Barlow giving an effective focal length of 1500mm in 35mm film terms ( effectively 2250mm on an APS-C sensor ! ) .
I'djust picked up a ( then ) new telescope , a 750mm reflector with a primary mirror of 150mm diameter which gives an effective aperture of f/5 .
Quite big , for a camera .

Hey all.. been a while. I am still on my lunar obsession and doing little with my DSLR gear these days.

I have finally learned enough to make decent colour images with "one shot" astro cameras. (Colour Astro cams) They are tricky to get good colour out of for the moon. DSLRs in comparison have fantastic built in colour science - astro cameras have none. At all. haha

I have had four decent results this year so far - here is possibly my favourite. I captured it at 50% higher magnification than I am sharing - for a nicer image quality. My telescope could be considered a "980mm F7" lens and I used a 3X extender. My camera has a 9MP 1 inch square sensor with 3.8um pixels. At the almost 3000mm I shot this at, it took ten panels of 2000 frame videos to make this picture. Hope you enjoy. :) More tech details at top left of pic.

Click pic for full size.

Clear skies!!
