Sunspot in AR2733 in High Res HA | Jan 23rd 2019

Heya, I woke up to clouds and humidity, but it cleared up a little while later to my surprise, so I was able to grab some data on AR2733 and check out the new sunspot. I imaged but also did visual with the 6" refractor with some binoviewers which was quite a treat. B&W: Single Stack: https://farm5.s...

Re: PST Etalon with a Quark, Log & Results

Heya, Played around with tuning today a little. Had a chance to see if I could do some tests between clouds, which I was lucky to have some decent seeing and some finally fairly good weather and a nice new sunspot has evolved, so a great way to test tuning. I can't seem to eliminate the double limb....

Re: PST Etalon with a Quark, Log & Results

Yea, I'm sure I'm aggravating the limb with processing. I'm trying different approaches to see if anything can work without blasting the double limb as bad. I agree I'm probably still not perfectly tuned on band. It's hard to know where I am with the tuning since there's no guarantee what any partic...

Re: PST Etalon with a Quark, Log & Results

Heya, I tried some more tuning options and processing options and I'm happier with the results today on the limb. Even though the double limb is not 100% eliminated, it makes processing it out a lot easier and more natural looking to me at least. Here's today's results under really excellent seeing ...

Today's Prominences & Spicules in High Res | HA | Jan 13th 2019

Heya, Rained all morning. Sunny Florida! But around 2pm the weather was nice and the seeing was unreal. Seeing was camping on 3/5 and would hit 5/5 significantly often. I find that post-storm seeing is always better than pre-storm. I don't know why. But I always seem to gather superb seeing after a ...

Re: PST Etalon with a Quark, Log & Results

They're all good but I do like number 4. Any chance you could put an unprocessed (straight from stack) version of this image? I'm curious as to what your raw data looks like before processing. Sure thing, Here's the Quark on it's own and the Quark + PST Etalon, no processing, just raw output from 1...

Re: PST Etalon with a Quark, Log & Results

Heya, Had a chance to try and test tuning again. I tuned the Quark far blue and far red to see which direction was the closest to match the PST etalon. The red shift was the worst of the two directions. The blue shift, all the way, where my Quark is normally sitting, was off a bit too. But I found a...

Heya, Woke up to some clouds, bummed, so just carried on with the morning. Noticed some light off my kitchen faucet so I peaked out and the clouds has moved on and I had a little window between more weather. I did some testing and gathered data on the brighter prominences and while scanning the chro...

Re: ERF and UV filter with 152mm f8 refractor and Quark

Heya, I have a 150mm F8 that I use. I do not recommend using it without an additional ERF. I find that the 2" UV/IR cut filter with the Quark alone works fine up to apertures of 127mm. But at larger apertures, the tube currents start to become problems and the overall thermal load is too much for lo...

Re: PST Etalon with a Quark, Log & Results

Thanks Mark, that's a good point about starting with the PST and then the Quark for tuning. I'll try that next session.

Re: PST Etalon with a Quark, Log & Results

Some more testing today. I left the Quark at 12 o'clock and then just tuned the PST a little back and forth to see what would happen. It would basically go from a featureless grey smear to a starkly over-exposed white. So between the two I just went for the most uniform across the FOV with contrast....

Heya, Had some fair seeing and a relatively clear sky this afternoon so played around with what's out there, two fairly bright prominences and a large active region with some plage and filaments, but no spots currently.

Re: PST Etalon with a Quark, Log & Results

Heya, I managed to test a little bit today. I tried tuning the Quark differently to see if I could match the PST. I usually tune the Quark to 9 o'clock as I find it has more contrast there. Tuning the Quark at 12 o'clock was my first round of testing, but then clouds came in. I think it helped a lit...

Prominences, Minor AR | HA | Jan 8th 2019

Heya, It's been a while since I saw the sky. Had a little time this morning. Seeing was ok, not great, but better than mid-day. Clouds rolled in, but I managed to get a little bit on those feint prominences around the limb. They're all small. The latest undesignated AR has lost a lot of its activity...

Re: PST Etalon with a Quark, Log & Results

Good point about being on band. I'm probably off-band a little. I usually try to push towards the blue side as it seems to have more contrast on the surface. But that was the Quark by itself. If I ever get a clear day, I will try to tune the Quark and the PST and try to document it with different ex...

Re: PST Etalon with a Quark, Log & Results

Hrm, It seems the limb is still present there too. It's not as stark, but you can see the transition as it's mostly without spicules and texture and has a blur to it. I have similar on my double limb. The super obvious double limb line goes away, but you can still see some kind of continuum leaking ...

Re: PST Etalon with a Quark, Log & Results

Interesting! Can anyone speak to the placement of the PST etalon (with collimating lenses) with an F10 SCT? Will it need to have extensions or how does one measure things out there? I know they're used with SCT's commonly, but I'm not sure how the focus system is handled, compared to the refractor s...

Re: PST Etalon with a Quark, Log & Results

Thanks, Does the PST etalon require the collimating lenses for a native F10 beam already? Or are they there to create the F10 beam? I'm curious when it comes to putting the PST etalon into a SCT design telescope. I will soon be trying this on my fully blocked C8 Edge, F10, so I could potentially mov...

Re: PST Etalon with a Quark, Log & Results

Do you think there needs to be something after the PST etalon?

I've always though it strange that the train was Quark (with a blocking filter) -> PST Etalon -> no lenses, no glass, no blocking filter -> camera sensor.

It's close to cutting the skirt down, just not quite there.

Very best,
