Sunday Sun 9th June-Ha 250mm RCT

An unexpectedly sunny Sunday morning after a really wet and windy Saturday. I thought I'd give the RCT a trial....

Basler acA1920-155um (IMX174)
Full size Aries tri-band ERF
SS Lunt 35 etalon
2.5x Barlow with red filter (Ha 7nm FWHM)

I found the red filter significantly beneficially boosted the contrast (albeit with a loss of image brightness). Much better with, but I guess it depends on the seeing conditions and the ability to freeze the action.

A little activity in the chromosphere:

These are the best of a dozen SER files.

Thanks for looking.

Stu.

These are excellent Stu! I couldn't come anywhere close to this detail with the HaT today, the seeing was shot for me.

Great shot from the RCT Stuart :bow

Could you post a pic of how you mounted the etalon on the scope? I'm sure you posted it before but want to refresh my memory.

Thanks,
Brian

Stu:
Nice trial shots, looks like with big scopes one has to learn a lot.
Best regards,
Eric.

Well done :hamster: some nice detail in there Stuart :bow I am guessing the seeing will never be that good after a big storm front but at least you managed to view the Sun which was a better than me. By the time the Sun is over my trees in the morning it was already clouding up.

Many thanks everyone. I really appreciate your comments.
As I say, adding the red filter really made a huge difference, bringing up the contrast and making details really 'pop' . I'm wondering about adding a (dare I say it), Quark in place of the plain red filter.

Hi Stu...

I remember the configuration now that you posted it. I forgot how how long the completed assembly was, but it does produce excellent images.

Very nice results, Stu!

BTW Can you send me the best raw stacked image? I guess it can be more deep processed with hope for more details seen.
