First Light Daystar Quark Chromosphere

Post by Alto »

Roughly processed; AS3 & Imppg. More practice needed! I've not had this much detail on my Lunt LS60tha!
Tuned on setting I received the unit.
No flats applied
William Optics 102GT + diagonal + uv/ir cut + tilt adapter + ZWO 174mm (cool)

Tuning at around 9 minutes from switch on.

A few images -

Promising start Geoff!

My advice at this stage; try images around either side of the dial setting you worked on, look for even illumination and contrast across the field of view with most detail. It don't look far off in the images above.

Try ticking 'crop' in AS3 when you stack, it will get rid of the jaggedy edges to the image.

Appears you have a decent copy of a quark.
I am looking forward to seeing more.....

Welcome to the Quark club Geoff. When you get a chance you should should do a series of test captures on the same area of the Sun, retuning your Quark for each exposure. Then stitch them together for a comparison.

Here's a series of captures I took last week, these are raw stacks each with exactly the same capture settings ,with no flats or post processing. It will give a good indication of the optimum settings for your Quark.

The Quark does seem pretty evenly illuminated.

I find my best tuning to be -5 (negative 5). I think several of us do as well.

While I'm recovering next week I'm hoping I have enough brain cells to put together my version of a processing tutorial to add to the number of other excellent choices out there.

In fact, I would not mind taking a stab at processing those files myself to see if it is capture or processing. How big are your AVIs? Maybe I can dropbox them...

Thanks guys. I'm fairly chuffed with what I managed at a starter. I fully intend checking each setting and I'm slightly assured that it took only 9 minutes to come upto temperature. An earlier attempt powering through a Pegasus Ultimate didn't yield a green light after 20 minutes - strangely!
After a brilliant morning of sunshine, yesterday, Friday has dawned cloudy! Och weel that's weather.

@jack - the above files were each around 5GB (1000frames). I also took 4 in sequence as the Quark warmed up, they are around 3GB (500frames).

Another story to this - I purchased a 102 refractor, f11, specifically for this Quark - sadly its focus comes in at 150mm - Quark, tilt, zwo174mm are around 170mm length! There's an option to remove the lower 120mm of the tube, but the guy who fitted it at the factory over torqued one of the three retaining screws and stripped its hex drive.

Pick up a stripped screw head remover for about a fiver, that will shift it.

Thanks Mark. That's a new one on me. I've previously just drilled out the screw head - but that was in wood and less delicate! Am a little annoyed the shop hasn't gotten back to me.

If you like, PM me and send me your AS3 tifs. I’d like to experiment.

Something like that should work. I only had a quick look so you might find cheaper alternatives.

Thanks Mark - there's a couple of youtube videos that have offered some ideas to try.

Finally I've managed to coax the screw loose. There was very little in the head.
A bradawl pushed gently in had enough purchase to allow grip and removal!

Phew.

It's annoying I've seen little of the sun since this first light - now I have the scope fixed we're away for a couple of weeks.
Sun'll still be there in October, won't it .........

Is there a minimum temperature for use of the Quark?
