Could see 2529 for the first time this morning



127mm f=1200mm refractor, DMK41, 2X Barlow, solar continuum filter.

GREAT!!!

I like this fine detail in the heart of the heart

Hi I had only a few minutes of clear sky this morning, interrupted by showers, and at 53 deg North the sun only barely clears the neighboring rooftops. This is a mosaik of 13 videos with a 70/700mm PST mod https://c1.staticflickr.com/1/593/23008080345_4a61b5b5f8_b.jpg higher res The large horseshoe ...

Hi I managed to take a time series of the large promience when it prepared for liftoff. 70/700 PST mod + 1.5X Barlow, DMK41. Here is a link to a video animation with 10 FPS and here one with interpolated 5PS . 60 Images taken with Firecaptures autorun function during breakfast and showering :) And h...

After some long time I had nice sunshine in the morning.

This morning I narrowly managed to make enough recordings in periods of relatively cloud free skies before the sun moved behind the roof.

Group 2403 has developed enormously since I saw it last 4 days ago: 127mm FH refractor, 2*barlow, Herschelwedge + ND3 + Solar Cont. https://farm6.staticflickr.com/5702/20785442536_0f3d4d67fe_c.jpg In H-Alpha (70/700 PST mod, 1.5 X Barlow) https://farm6.staticflickr.com/5828/20625137038_800aa189a2_c....

Thanks to all these comments.
Here are the original videos:

Hi Today Calsky indicated a double solar transit 20km north of Hamburg, Germany, where I live. Fortunately my mothers place was inside the region where both transits were visible. https://farm1.staticflickr.com/614/20171941284_2e79e2b917_b.jpg Data: Pentax 75 SDHF @ 500mm, DMK41, TAL glass full apar...

That is really outstanding! Especially the level of detail visible in the attachment!

Had very decent seeing this morning. Starting out with 2396, preliminary processing. By the way that thing was visible with eclipse goggles only as a dark spot in the solar disk. https://farm4.staticflickr.com/3723/20426707345_087836344f_c.jpg 127/1200mm refractor, 2X Barlow, Herschel Wedge, Solar c...

BTW I'd like to see WL images in somewhat larger scale. May be a 3x barlow will be better for finer details? Here are some links to higher res versions. My 2X Barlow effectively already yields approx. 3X (f/30) as the Herschel wedge gives considerable extra extension. This exeeds the Nyquist theore...

Yesterday I had the opportunity to do some imaging with Cirrus clouds interfering and usable but far from perfect sseing 2394: https://farm1.staticflickr.com/371/20177532230_338e214bbe_c.jpg full disk H-Alpha https://farm1.staticflickr.com/373/20365654255_cb55a617be_b.jpg (More resolution here ) Thi...

WOW.

Hi, I had some sunshine this morning, with medium seeing and cirrus clouds moving through. Group 2396 is rapidly developing and shows flare activity in H-alpha https://farm1.staticflickr.com/403/20132247959_6c5157f09e_b.jpg 2394 has declined a littlebit in activity https://farm1.staticflickr.com/560...

This morning I had hardly enough time to capture 2394 as thick cirrus was coming up.

Hmm, here is a softer version (sharpened with Photoshop and not with Registax)

Thanks for your comments. I just add some images from August 2nd, through cirrus clouds, same technical data: https://farm1.staticflickr.com/343/20036947720_5b616b2af0_c.jpg https://farm1.staticflickr.com/502/20036952448_210a2d050c_c.jpg https://farm1.staticflickr.com/517/19603971983_a5be57db0f_b.jp...

After some days of bad weather I could see the sun once again. Here are 2394 1nd 2393 https://farm1.staticflickr.com/427/20020390799_93e251da39_c.jpg and this is 2391 during a period of better seeing https://farm1.staticflickr.com/531/20018560970_03ece75ac5_c.jpg A farewell shot of the large group 2...

Hi With clouds permanently interfering I had no big hope that I could finish up a H-alpha full disk, but I narrowly managed it. Overlap was insufficient, so I had to toggle in Photoshop to finakky get it. https://farm1.staticflickr.com/402/19615302460_aaea102f67_b.jpg More resolution here 70/700 PST...

The closeups are phantastic

Do you intend to use the refractor for anything else but H-alpha? If not: For our 70/700 PST "Sunlux" mod the host scope has a lousy 1.25" focuser. We simply cut the tube precicely that the backfocus (distance between the rear of the adapter and the focus) is identical to that of the ...

Hi Just figured out that there are 2 generations of Baader's solar continuum filter, which I use routinely for white light imaging. To reduce the chromatic abberation of my 127mm FH refractor I used a G-Filter. A friend borrowed me a Solar Continuum Filter for testing. I was quite shocked when I fir...

What scope is the 127/1200? Bresser-Messier-AR-127L-1200, its a Fraunhofer lens. https://farm8.staticflickr.com/7527/15956894751_06672f3ce7_c.jpg https://farm9.staticflickr.com/8678/16809389476_0495509810_z.jpg Got it very cheaply when they restructured their program - it had been on display at the...

Phantastic

I tried and compared both. Autostakkert. Easier, faster, better.

Hi everyone Had some quite bad seeing this morning, but when using 5% of 2000 frames it was still usable. 2381 has develepod quite a bit and shows some intersting structures https://farm1.staticflickr.com/427/19472045756_eb74b2d1ec_b.jpg (127/1200mm refractor + 2 X Barlow + Lacerta Herschel wedge + ...

Here are some images from today. Weather was extremely hot here in northern Germany, and skies were extremely milkey. Anyway I tried some images with the 127mm FH refractor This is 2375 https://farm1.staticflickr.com/382/18808925654_22b268ab1e_b.jpg and here we have a moasik of 2373 and 2376 https:/...

Alfred, I took videos with 2000 frames and used 6% of them in Autostakkert. This eliminates a lot of the seeing problems. Concerning heat input into the tube I don't consider this a major factor. The scope won't heat up very much except directly at the focus. The prism is quite a few centimeters awa...

These are some 2371 images when it was still in the center of the sun. https://farm1.staticflickr.com/274/18605933744_d8cd18310c_b.jpg 2015-06-20 https://farm4.staticflickr.com/3719/18412207273_d3e7a7c80b_b.jpg 2015-06-21 All done with a Bresser 127/1200mm FH refractor, 2X Barlow, Lacerta Herschel w...

Hi Just saw this forum and just needed to register. Completed a PST-mod some time ago, based on a 70/700mm "Skylux" refractor. Some years ago these telescope were offered here in Germany by a discounter (Lidl). They normally have decent optics but a lousy 1.25" focuser, and used ones ...
