17-04-2023 Daystar Quark Chromosphere

[Ewan]

It's been quite a while since i have posted here, new things, new media, busy life & terrible UK weather, but i shall endeavor to remedy that.

My solar season got delayed by about six weeks with the constant rain but finally managed to get some afternoon sun on the 17th April, well worth the wait & the Quark got to stretch it's legs once more.

I tried running the rig at F38 but not 100% i noticed any difference to be fair, i plan on doing some F ratio tests when i get the chance though.

Atb solar peeps

Its amazing the difference in aperture makes as well as larger f ratios.

Indeed, with that D-ERF size & frac my rig was at F30 but higher ratios should give a tighter bandpass

Spectacular images 👍

[JeremyS]

Extraordinary 👍🏻👍🏻👍🏻

[Kon]

Fantastic images. Some of the best I have seen.

[David Smith]

The weather certainly is a challenge. See you've not lost your touch though, great set.

[GordonD]

Amazing images. Not sure I have ever seen anything quite so detailed before.

Hi buddy, the weather...cor, it's been something else hasn't it, I remember about 5-6 years ago it rained sI'd for 13 weeks, got to be good soon surely.

Some half decent seeing played a large part, as it's still not that warm I started the heater on -3 instead & it seemed to give best results, I also changed the tilt applied to over half as I am sure it can cost you in making the bandpass wider giving less contrast.

I know the words incredible and amazing have been used, but, those images are.

When you  can see the power of Sol up close like this it's almost frightening!

Your right Maw, it is what drew me away from DSS imaging, that & lack of sleep 😉

Phenomenal imaging Ewan - wish I could get to that level ! 👍
I'll have to pick your brains at some stage...
Are you an AS! / ImPPG processor or using that AstroSurface(?) software...
Super going anyway - something to aspire to 😀

Clear skies...

Omg these are stupendous! just gorgeous amount of detail!

Very kind, thank you.

I use Genika Astro for captures, AS!2 314 64Bit (think thats correct) for stacking & just ImPPG for processing.

As my 152mm is only F5.9 the ratio would be a little low for the Quark tbh, i went with the 135mm D-ERF as its clear aperture is 125mm so with the Quark it my rig is at F30, having read quite a bit over the years & trial & error i masked the scope down to 100mm to get to F38 but still testing this out tbh.

Been testing the heater setting on mine & on the 17th found that -3 gave the best on band display. I also altered the tilt amount on the Interference Eliminator to about 50%, i can still see very faint banding but nothing a flat frame cannot sort out.

Trial & error & testing your kit pays dividends in the end.

Thank you, as i live right on the coast, surrounded by victorian hot roof houses & this was the afternoon even i was a little surprised tbh, always worth having a go though

Thanks for the details Ewan... 👍

If I may, I'll pm you at some stage to get some more pointers...

But it's time for bed now...

I'll be bookmarking this thread though as a future reference point!

Stunning detail and an incredible sense of perspective.

Your seeing conditions must have been truly extraordinary at the time you captured data for these images.
This is not to take away anything but breathless admiration for your skills.

Will solar imagers now descend on Hastings? Like they do for an eclipse? 😊

Buy Daystar! Quark sales will be going through the roof!

[Alan White]

Amazing to see these, thank you for sharing.
I have just bought a 152 5.9 in Altair Red for Solar WL,
But now its setting the Quark idea off once again...

Honestly the seeing for that day wasn't that good, cloud dodging at times plus the sun seemed to have that 'high white misty' look to it, i was surprised at some of the detail. I do captures at 3-6ms & limit them to 30 seconds only.

I did make a small change to the amount of tilt & did an 'on band test' before capturing.

Thank you, not long after getting the 152mm & IMX174 & posting a few images it seemed like a lot of imagers went the same route, it is a good setup & the 5.6um with the camera is a good match for the 152mm.

Only thing i will stress about the Quark if you own one then you really need to do test runs with the heater settings to find what one is best & it may not be the best for all sessions either.

Superb set of close up images, very dramatic as well
