Hi, Warren

I really like the details in your disks.I tried imaging the long polar filament in higher res but, as you said, it's too wispy to present effectively
although your inversion suceeds more than my efforts would show. Well done.

I can hardly wait until the fall when the seeing usually gets better. In the meantime, I'll keep hoping that the soupy sky will produce some moments of worthwhile results as the ones below. I used a 127mm scope with a Quark and an ASI462 for the prom and a PO533SQ for the wider views. I forgot to me...

Thanks, Warren

I've also been disappointed over the last couple of days on the lack of larger scale features, especially on the limb.

From an otherwise uneventful day of bad seeing and cloudy skies comes a pair of images showing the growth of a surge prom and a detached prom tenuously connected to it. I used a 127mm Stellarvue refractor with a 3X Baader telecentric and a 1.5X barlow attached to its nose which gave me an efl just g...

Since my Lunt 152 had not seen the sun for a while now, I decided to haul it out and use it to image the large filaprom that was rounding the limb on this day. It didn't disappoint. The scope was double stacked with a Quark Chromosphere. Unlike many filaproms I've seen this season, this one was very...

Thank you for your posts, Maurits. I have always enjoyed and will continue to enjoy your work in future. I want to add my best wishes for your
recovery.

These 2 proms were taken during a short session on Aug16 in typically bad afternoon seeing. I used an LS40T etalon + 12mm blocking filter on a 127 mm scope.

Hi, TareqPhoto The Lunt 40mm front etalon is from the LS40T solar scope: https://luntsolarsystems.com/product/lunt-40-mm-dedicated-hydrogen-alpha-solar-telescope/ The scope itself, new, is less expensive than the current Quark ($749 versus $1295 USD). The 50mm front etalon (I have the LS50C) is a st...

gabrieli

The new double stack is based on a configuration I read about in the past on this forum. It consists of a 40mm Lunt front etalon in an enclosure sold by RAFcamera with a Quark Combo attached to the enclosure. This was attached to the end of a 127mm scope. T threads on either ends of the enclosure ma...

gabrieli

I can say that, this season, I feel that I've had to do more processing than usual to get acceptable final results. I hope this isn't a trend. I also hope some larger scale features appear soon. Here are the results of the current sessions from Aug4 and one from Aug5. Last year my AVX mount was expe...

Hi, Mark

What an enviable adventure you're on. Thanks for posting your route.

Lou

gabrieli

This was a disappointing session in a few ways. There were few features that were noteworthy on GONG or in my live view. Images were very flat in contrast due to the milky sky. One of the limb images had an emerging AR (unnumbered as of this posting) that I thought had some interesting turbulence th...

gabrieli

Although there was less haze in the sky this session, the seeing was worse than the previous couple of sessions and so I cut the session short after recording 6 files. When I processed the images, I realized there was a ghostly section of the prominence above its left end. Lou Prom.png Promc.png

gabrieli

There was a wide variety of features visble this session. I started imaging when the sun was just grazing the sloped roof on my house before that part of the roof had a chance to be heated by the sun's rays. During this time the seeing was better than usual (about 20 minutes). Then, the seeing deter...

Hi, Petr First, I have to say that you must have the “golden touch”. Any equipment you use produces beautiful results. I know that your hard work and skills are the reason for your inspiring images. Secondly, you only take 4 minutes to set up? How fast were you moving? It takes me 4 minutes just to ...

gabrieli

Will this haze ever go away? The sun was a dull hazy ball through most of the day although it didn't reduce image detail as much as you might expect. The image contrast, however, was flat and had to be boosted in processing. I used an LS152 + Quark Chromosphere recording on a PO533SQ for all the ima...

I wished the ASI178 with its high resolution had worked out for Hα.
For me, that camera (ASI178) displayed a horrible grid pattern that this camera (462) does not.

Lou

gabrieli

I continued my trials with the 462 this session in very hazy conditions. I set up in time to record 3 files before it clouded over completely. The sky cleared into hazy skies in the afternoon but I realized by then that the 3 files I recorded would be enough for now. I hope to use this camera when t...

Hi, Arne

My favorite white images happen when active regions and sunspots are near the sun's edge as you have shown here. Impressively imaged with your TS102ED.

Lou

gabrieli

Similar to what some people have experienced at first with this camera, the camera was not recognized in Firecapture. I knew from some past experiences that what was required was an update for the driver and also a transplant of new ASICamera2.dll and ASICamera2.lib files from the SDK into Firecaptu...

gabrieli

Some unusual prom groupings were the highlights from this session. I also wanted to show details from these groups and an overview of all the activity around the sun's limb. Most images were rotated for better viewing. Lou FD.png FDc.png p1.png p2.png p2a.png p2b23 at 7.09.07 PM.png p3.png p3c.png p...

Hi, James

Thanks for the mosquito pupa reference and image. I couldn't quite picture what you meant at first but the image cleared that up.
It's fascinating how eclectic people's interests are besides (just) solar imaging.

The image on GONG did not give a good impression of how strange this prom looked. It made a strong impression when it first appeared on my screen. I used a single stacked 127mm Stellarvue at 4400mm (f/34). The full disk was taken with the usual LS60MT, using a 2 image stitch of two 3/4 disk images. ...

I would decsribe the seeing as a shimmering mess today, probably because I was shooting close to my roof looking east and I didn't really give the scope enough time to acclimate. The images below are the higher res images with a single stacked 127mm scope with a PO533SQ. Limb images are composites. ...

gabrieli

The forecast predicted partially sunny skies for this afternoon. The sun appeared in between hazy clouds at about 2:30 pm. There was enough time for at most 1500 frames or less before dense clouds appeared in the view. The results are passable given the changing conditions. hopefully, I'll have more...

I used my single stacked 127 mm scope at f/32 (4200mm) on a PO533SQ for this session for the higher res images and the double stacked 60mm Lunt scope for the full discs. There were a lot of interesting features on display. Lou FD.png FDc.png FDinvc.png edge.png edge2.png edge3inv.png edge3invc.png s...

gabrieli

Well, Stuart, your seeing was better than my jittery excuse for a sky.

The prom image looks very dynamic. I judge my seeing by how well defined the "spokes" are in the sunspots' penumbras. They look well defined in your AR images

These "white" light images were all taken with a 127 mm scope with a 4X PM on a Baader prism + SII filter recorded on A PO533SQ camera with the ROIs indicated (approx). Full sensor full sensor.png full sensorc.png Half sensor half sensorc.png half sensor.png Quarter sensor quarter sensor.p...

The mediocre seeing continued this session but experience told me to wait until the processing is done before making a judgement on the results. The variety was entertaining. For Hα I used a 127 mm scope with a 135 mm Baader ERF in front and 4X PM with a Quark Combo with a PO 533SQ camera. The camer...

I planned to get out as early as I could today since thunderstorms were predicted in the afternoon. The sun high in the east clears my house at about 10:30am and so I made sure to set up well ahead of time. I first tried using Baader solar film on my 127mm scope with a 4X PM using a 2" SII filt...

gabrieli

I didn't want to broil in the 32˚C sun today and so I recorded in the shade of my house at about 11:00am while the hardware was in the sun doing the
optical work. I only aimed to gather data for a full disk and that much was accomplished.

I was strongly hoping that this AR would still be visible this day and I kind of got my wish. It was still visible but the seeing, initially tolerable at 10:30 am for white light imaging, became horrendous for Hα. I used an AR152 scope with a 4X TV Powermate and a Baader prism. This prism allows you...

The forecast for today was pretty miserable especially since sunpots near the limb are an appealing subject. Well, with luck, forecasts are a bit wrong and a variably hazy sun appeared. I set up my AR152 with Baader 3.8 film , a 2" SII filter on a TV4X attached to a Player One 533SQ. The follow...

Hi, Petr The highest scale I've ever reached with my 152 mm, with passable results, is about 4500 mm with contrast and sharpness not close to your images. The scale of your images, assuming your scope is the 210 f8 is close to 7000mm and the final images still have great contrast with smooth details...

Mediocre conditions continued today with hazy skies through the sessions on these two days. I took some white light images on June 30 of the large 3354 active region and some Hα images on June 29. For the white light images, I used Baader 3.8 density film on a 127mm Stellarvue with a 4X Powermate he...

gabrieli

Good day, Petr. I wonder how much better your images can be. These are stunning with such impressive detail and contrast. Now that you are taking a
break (temporary?) from engineering more telescopes, you can enjoy producing more images. Thanks for posting.

Lou

gabrieli

Hi, Petr

It's always great to start the day with your wonderful images. Now, if only I could borrow some of your sky conditions. When I try and use an aperture of greater than 152 mm, the image quality does not improve.

Lou

gabrieli

This is a scope I've had for some time but seldom used. It will eventually be double stacked once a new front etalon arrives from Lunt. Until then, it will be used in single stack mode with the same ERF as I use on my 127mm Stellarvue. It's, of course, easier to handle than the larger scopes. I used...

gabrieli

A mixed bag today both in terms of variety and quality. The first 4 images were taken with a Player One IMX432. I used an LS152 double stacked with a Quark Combo with a TV5X Powermate. I don't usually go that high with barlows but I wanted to see how the camera would handle that focal length. One ob...

gabrieli

Today was a clear, warm day with jittery seeing conditions. Intruments used were my Stellarvue 127 in singlestack and LS60MT in double staack. Hopefully, the Stellarvue will also be double stacked soon when Lunt ships an LS100F front etalon to me. I'll be losing about 2.7 cm of aperture but I don't ...

Since there was a lot of activity along the limb, I decided I'd best use my LS152 double stacked with a Quark Chromosphere for imaging. I set up at about 10:30 am looking high to the east just over the roof of my house and I saw the seeing was decent.For the higher res images, I used the LS152 with ...

Thanks for posting your experience. My 0.5Å filter has been back at SS since Nov 2/22 and not back yet (this is not a complaint although I'm anxious to get it back and start using it this season).

These are remarkable images from an 80mm scope. Nice work.

These images are glorious, Petr. I especially like the texture on the solar chromosphere and also the tones on the floating prom in the next to last image.

Too often in my area, skies are very iffy, where clouds are present with occasional "peeks" between clouds that last a few seconds. Most often, unfortunately, sessions like this don't produce many worthwhile results. I managed a single full disk but using only 50 frames out of 200 frames f...

Hi, Pedro Beautifully presented images as always in your posts. I fully agree with your experience with this camera in terms of gamma causing what looks like noisy speckles in the area around proms (for me). It looks terrible on the live view but somewhat more tolerable when imported into PS for pro...
