Excellent Ewan. The animation is fascinating.

Thank you, just a shame it didn't last longer

Good results there 👍, shame the weather isn't so cooperative but lots of sunny ones to come. I've a feeling this year could produce some of the biggest spots seen...fingers crossed. 

Keep it up buddy 😉

Awesome set !

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...

 

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.

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!

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.

Omg these are stupendous! just gorgeous amount of detail!

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

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...
Damian

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.

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 😉

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

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.

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

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.

Solar imaging TOTALLY nailed 😲 

Thanks Den, life got seriously hectic for me & i lost touch with the forum & sometimes trying to fit everything in just was not doable, good to be posting again though & glad to see your still here fella 😉

Agree with the others. Absolutely stunning videos! How long in real time are they taken over?

Malcolm

Cheers, roughly an hour. Those particular 'events' were extremely fast on my capture screen in real time so best bet is fast exp time for less time otherwise you can end up stacking blury frames, I was at 6 or 7ms on those 2 but tbh honest 3-4ms for 5 secs would have been better.

If it's been a while you certainly haven't got rusty... Cracking images and awesome animations... What's your setup?

Been a good few years now i think, one thing & another i kind of lost touch with this place.

My setup is AZEQ6-GT  152mm Technosky Achromat F5.9, Baader 135mm D-ERF, Quark Chromo & Point Grey IMX174 mono camera.

Not posted anything for way too long, a few captures from April this year.

Atb

Thanks

Way too warm for anything really good on Friday but clear skies means the gear comes out.

A few Ha caught but more WL than anything tbh

Have a great weekend people

Now that came out really well Charl.....;-)

Spot on mate !!

That's a pretty neat BIG set there fella 🙂

Which parts of Hastings are higher than Mauna Loa?

Lol I wish haha

Interestingly on Gary Palmers solar imaging talk last Sunday he said he gets better results with AS2, don't think it can handle the ZWO ASI178 images though ?

Dave

For sure Dave, I noticed it a while ago, I knew 100% I had good data, put it through AS!3 & got a very blurry image, tried !2 & it was fine. Ive probably binned good data because of it

Love these 😉
