Only one image which is really annoying because it was a nice clear day even if the sun is surprising quiet. This is AR11410 with AR11413 above it

Newton rings have made a reappearance using the DMK41 and 2.5x Powermate which consumed most of my time today, very frustrating lol. On the plus side my prototype motorised focuser works very well and I've now ordered the pulleys and belt drive to finish it. I've got an EQ6 Syntrek mount waiting to be unwrapped at home so I've got all the bits for the summer (until the next toy comes along )

Image taken on a PST Stage 2 modded Lyra Optic 4" f/11 refractor (LOHA) with a DMK41 CCD camera without a Powermate

Excellent work Kev

kev,

Lookin' good!

We've had -8 degrees and milky skies..for the ten minutes Sol cleared the trees.

BTW I've just removed the "mini-ERF" from a BF15 mounted on my 88PST and find it definately helps suppress the ghosting...well worth trying. The BORG 1.25" non-rotating focuser is a joy to use - should have done it before!

Ok you got me hooked, where do I find the mini ERF on the BF15 and how do I dump it? More light is always good for exposures

The Borg focusers are very smooth and give a nice fine focus control, I do like the larger one fitted to my system.

Very nice!

Look into the "front" of the BF diagonal..the "mirror" filter you see is the "mini ERF". I found a 6" steel rule was good to undo the retaining ring - the filter just drops out - careful!!

I'm sure you will notice the difference.

"Front" = Scope side ? or Eyepiece side?

[Merlin66]

Yes, "scope" side; inside the nose piece of the diagonal.

Good stuff Kev! How many frames are you shooting for this and how many are being used for the stack?

At the moment 60 seconds of video at 15fps and I'm using the best 25% in Registax v6

[Cschur]

That looks like a very active region right now. I cant wait to see how it develops over the next few days! Nice shot!

[Montana]

A cracking shot, well done!

It's incredible getting so close to the Suns surface, and digging out such fine detail.

Lovely job.
