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. ...

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...

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...

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.

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 ...

gabrieli

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). My issue was that with an 11mmx11mm sensor almost half my image was covered by a weird irregular shadow...

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...

Forest fires in Quebec have been affecting both the US east coast and my area in Woodbridge north of Toronto over the last couple of days with June 6 being the worst day with haze and burning wood smell in the air. during the last session (June 7), the haze and odour were still present, though not a...

The sky this morning was very hazy with a burning wood odour in the air and so I had to try again in the afternoon for the images below.
I used a LS60F on the front of an LS60MT with a 2.3X Baader barlow lens on an ASI1600.

Your images are an inspiration. I also have a 432 from Player One but have not yet produced images like these or others you have posted beacuse of my sky conditions.

Variable clouds were predicted and delivered with some gaps allowing about 500 - 600 frames before passing clouds would spoil the view. For the first time this season, I took out my LS152 double stacked with an original Quark. The LS152 seems heavier every year but still works perfectly with the pre...

Full disks are always a good distraction when the seeing doesn't support higher resolution. I used a double stacked LS60MT on an ASI1600 camera to produce a 2 panel mosaic.

Despite a fairly solid blue sky, seeing conditions were only enough for full disk images today. I used a double stacked LS60 MT for a two panel mosaic.

Continuing variable haze caused a few artifacts in processing proms but the features in the disk came out reasonably well.

I've been jealously admiring the extraordinary work of posters on this forum for the past while. I finally got around to setting up my two mounts outside for the season under protective covers, an arrangement that worked well last year.

Besides warmer than usual temperatures being forecast, the sun was predicted to be out. That information coupled with the appearance of many interesting solar features, prompted me to take out my lighter tripod and mount (an AVX) and see what I could do.

The weather here continues to be unseasonably moderate for this time with clear blue sky but with mediocre seeing. I started with some white light efforts using a 102mm apo + 3.8 Baader film.

I thought the only highlight of my day was going to be to replace my furnace vent motor/fan (for exhaust) since my old one would sometimes start up with a brief squeeking noise (bearings).

I have a full disk from Nov 1 and many other features from Nov 2 . The weather was surprisingly mild for this time of year with a mostly cloud free sky.

gabrieli

These are very impressive images at this scale, especially since they were done with an LS80. I've only used for full discs and never thought of using it with a Quark. I'll try this combination this afternoon. Hopefully my clouds will be as kind as yours.
