The care you put into processing prominences is clear, especially in the last image with some beautiful tones. I share your experience with your 7 inch. I find it hard to understand how my two 6 inch refractors can produce good images and, in the same conditions, with some exceptions, using a 7 inch...

This session didn't have the better than average seeing that I had on Oct 22 and no really new features. So, I took out my 127mm Stellarview for a quick session. Here are the results.

It's a pity that days with the best seeing in my area tend to happen in the fall, often just before the season ends in early November.I still intend to image unusual events in winter but more likely with smaller scopes. For this session, there were not many features on the disk face except an extend...

Passing clouds played havoc with stacking in some files this session. Some subtle artifacts were left in the posts shown but left in or there would be no posts and unfortunately some prom images were not worth saving. Shutter speeds became longer with the sun being filtered through thin clouds. A127...

Hi, Mark

Great qualty images at 80 mm aperture.

Some horrible winds were blowing throughout this session and so I had to wait and gamble between gusts that I would have enough time to record decent video files (600 - 1000 frames). The scopes used were a 127mm Solarview and a LS60MT double stacked witha LS60F filter. fdinvc.png fdinv.png prom1.png...

The day warmed up a bit today making for a very pleasant session. Of course, you can't help noticing how low your scope is aimed for imaging. Conditions were still pretty good. There were many events worth imaging. I used a Stellarview 127 with a Quark Chromo and a double stacked LS60MT for the full...

This was a welcome sunny day where clouds held off for the most part.
I recorded 300 frames for the disc panels and the same for the proms and stacked 60 frames for each. Then the disc was superimposed carefully onto the prom image.

Hi, Warren Those limb shots are very dramatic. I don't know if you're doing this already but putting a large bbq cover over your rig will offer great weather protection. I've had 2 of my mounts under tethered covers down to the tips of the tripod since the spring of this year with no problems includ...

I had a short session this day with a sun that is getting lower and lower in the sky.
I used a 127mm Stellarview scope coupled with a Quark Chromosphere for the AR and a LS60MT for a 2 panel mosaic
for the full disk.

I woke up upset this morning, still remembering that my attempts to calibrate my 1.5 year old Solar Spectrum 0.5Å ASO filter were unsuccessful on the previous day. Instead of a temperature readout, like other models, the reference temperature is indicated by a “0”. You move up or down from “0” (-18 ...

After some rare sessions, you just can't wait to start processing the day's files. The main feature on the sun was a very dynamic looking filaprom. The limb features were bright enough to allow full disks to be processed as single images instead of composites. Unfortunately, there was also a bad rea...

Hi, Alexandra I’m sorry that there’s been such a huge change in direction about your imaging activities. I know that “talking about it” might feel like doing surgery on yourself but there be a lot of insight on this board that might be helpful if you do. Why not start with an image of the bottom end...

Thank you to all the viewers and commenters.

Hi Magnus

Unfortunately, I didn't record data long enough for an effective video. The part of the session using the ES102 for the prom was cut short by clouds but I actually never think of animations.

For once, threatening clouds stayed away from the sun until early afternoon after I was finished imaging. I used 2 scopes: a 102mm ES apo with a Quark Combo on a 3X Telecentric, and a 60 mm Lunt 60MT with a LS60F on the front. I attached strips of wood around the lens hood of the 102mm to allow the ...

A large prom is persisting for a while. As well, a smaller eruptive fast changing prom appeared. I also recorded 2 panels for a full disk using a double stacked LS60MT. If you note this full disk and my past ones, there is what seems to be a gradient from top to bottom. This is the result of my tryi...

Today, I had planned to do some higher res imaging of a couple of filaments on the limb (appearing and receding) and some full disks. Something weird happened. I had no apparent problems with the camera or software during the entire session. I recorded my higher res files and enough files for a full...

The seeing appeared steadier than usual in a hazy sky today but, at the same time, made images appear softer. I can already tell the sun is not as high as it used to be. The main feature of interest was a large filament on the limb which is presented below. I also have several versions of a full dis...

Another promising day on the sun. Th emain feature was the large prom which had a trailing tail that became feinter along its length. There were also interesting active regions around the disc. The scopes used were a Stellarview 127 and LS60MT. Lou FD.png limb.png limb2.png limbbw.png limbinvc.png p...

Hi, Warren I'll probably look for another colour scheme eventually to replace the pink tone just as I got a little tired of the more natural colour. Black and white is actually my preference too maybe because it reminds me of the first Ha images I saw long ago and perhaps because it involves less pr...

gabrieli

A very uncooperative sky today with a constant threat for clouds creeping into your frame. Recordings had to be limited to 600 frames or less to avoid cloud shadows messing up the files. While recording, I had to feep glancing up to check that clouds weren't drifting over the sun. At one point grey ...

Hi, Maurits

These are enviable images. This is why I love good quality hi res imaging although it is sometimes (often) difficult to achieve for me.

The forecast for this day was partly cloudy. I managed a few high res images. It gradually became completely cloudy and, after packing up, the sun reappeared. Out I went again to do some full disks. I used a Stellarview 127 with a Quark Chromosphere and an LS60MT for this session. Lou FDmono.png FDc...

Hi, Magnus For the first 2 images I used an LS60MT with a 3X barlow on an ASI 1600 and reduced ROI and recorded 1000 frames and stacked 15% or 150 of these.I rarely record more than 1500 frames. For the full discs (4 panel mosaics), I recorded 600 frames for each panel and again stacked 15% or 90 of...

I wanted the filament to be closer to the limb for this session but I guess that will have to wait until tomorrow. It should put on a nice show on the limb. In the meantime, here are some images of the filament and some full disks all using an LS60MT and ASI 1600. Lou filament.png filamentinv.png FD...

After a morning of hard labour resetting some paving stones at one side of my house, I looked forward to a short session imaging in bright sun in mediocre seeing. I used a double stacked LS60 + 2.3X barlow with an ASI1600. Each image comprised a 3/4 sized sun (top and bottom) for a mosaic. The horiz...

gabrieli

I'm hoping the long filament will turn into at least a couple of filaproms in a few days. Until then, here it is in its current state on Sept 6. All images were done using an LS60MT and ASI1600.

Hi, MAURITS

These are top notch images. I really like seeing solid looking filaproms on the limb. The double stack works well.
I have a Solar Spectrum 0.5Å etalon which I would like to double stack. Which etalon do you use in your double stack?

I decided I had to image the complex spot group before it moved over the limb. Fot this image I used a Stellarview 127mm scope with 3.8 Baader solar film at its base focal length for the full disk and with a 4X PM for the larger scale image all on an ASI1600.

This event came as a nice surprise this day as I scanned the limb for proms. The sky was mostly clear with passing clouds with enough time to record 1000 - 2000 frame files. I used either a ES102 apo double stacked with a LS60F in front plus a Quark Combo in back or a single stacked Stellarview 127 ...

The huge prom has stayed around for a while now and doesn't seem to lose its stature. What a gift! There was also an area on the limb that erupted to mark the passing of an AR. To record these areas I used a Stellarvue 127(single stack) protected by a Baader 135 ERF with a 35nm Ha filter on a Quark ...

Today, Aug 28, was an unusually busy time on the sun’s limb with all kinds of peculiar proms including the big prom and surging proms.

Fortunately, the skies cleared just after lunch for about 15 minutes and a second time at about 4:00 pm local time. There was time enough to image the big prom and later to go back for a full disk.

A big prominence dominated the view this session with smaller scale filaments and a few ARs.

Rain was predicted for the afternoon this day but never materialized. This made me start my session at 10:30 local time. In all, the proms turned out to be highlight with less happening on the disk.

Since conditions were somewhat uncomfortable this session, I had a short session sitting in the shade of my house most of the time while my LS60 basked in the sunlight.

Today was a good day for low and medium res images. I used a double stacked LS60MT and LS152, both recording with a ZWO ASI1600 altering the ROI. There were a many proms around but the main feature was a filament grouping approaching the western limb which I hope produces some interesting filaproms....
