The quark, but you could use it with the Lunt at longer focal ratios. (f25+)

Very good Ralph! Thanks for sharing!

Very good there Michael!

Absolutely stunning Christian! I never got to test my Alluxa CaK setup on larger apertures this year, that's for next year now! I tried triple stacking but using a CaK PST filter, but found it didn't offer great improvement (and the usual longer exposure time). I need to focus on tuning the filters ...

Nice disk thanks!

Thanks guys! Nice reprocess James, I don't mind at all :) The 'greenery' on the right hand side of the garden is pyrocantha https://www.rhs.org.uk/plants/pyracantha and is an evergreen. There are some leaves left on other shrubs in the garden which haven't fully come off yet, but it can't be long fo...

These are lovely results! Welecome to the forum. I'd spotted that CaH Quark had sold on FLO

Thanks Christian.

It would be good if Raf did an aluminium version.

Hi Stefan

I'd recommend a camera with an imx174 or imx432 camera. The latter will give the less zoomed in view.

Hi All, Despite the day starting with a heavy bad of rain for several hours, by lunchtime the sky had transformed to (nearly!) blue skies. It was very windy though and blowing the lids of all my scope cases shut along with nearly blowing the laptop off. I was chasing the sun with the travelling kit ...

These are excellent Christian, demonstrates the effect of focal ratio on CaK filters very well.

Thanks James! Just spotted the cloud breaking here, the rain has now passed. Hope your sore throat gets better soon. I'm sure a cool beery beverage will help later on

What are you using for blocking filters?

Excellent shots Les!

These are excellent Alfred, your best yet! Thanks, Mark. I am expecting much more from this setup. Need to put in more time to learn and optimise the imaging train, e.g. tilting the Alluxa filters as pointed out by Christian. Alfred Can you tell us more about the module Alfred - has it a 3d printed...

Hope all the moving chores go smoothly James. Chill out with a beer when all done later on.

Nice animation thanks!

Nice disk thanks!

Good result in less than ideal conditions Warren!

Nice animation!

Super capture there Ralph!

A lovely collection of images here Pedro!

Nice views there Warren! The seestar is a promising bit of kit for some easy deepsky.

Glad you got a view in James! Pouring with rain here (pre dawn) but it should pass throuh relatively quickly, fingers crossed after midday I might get some sun. Have a good Saturday!

Great additions!
