halpha sun of April 18

Good morning, everyone, a sunny sky at home but with a lot of cirrus clouds and wind and a lot of turbulence...and as, during the week, I can only make the sun late enough; a rather low target. In short, not easy, but fortunately, a little activity on our star today. At fs60 with sm40 double stack, ...

halpha sun of April 6th

Good evening, everyone, I finally almost saw the sun today...almost, because once I got off work, our star was drowned in cirrus clouds in my house! :( acquisition around 15h UT at the focus of the fs60 with sm40 double stack, glasspath x1.25, BF10 and zwo178mm with firecapture 2.6 (note that the ga...

Re: halpha sun on March 9th

Hi, NR = Newton Rings, I guess? I have a problem with NR because of the glasspath. But it's gonna work out with a good tilt ring adjustment. On the other hand, the 178mm pattern is more complicated to solve ( whatever the value of gamma )... except with a flat. Here, the same picture without flat (w...

Shame about the rings. I don't think a flat is a good idea with a full disk?😞 lots of detail in the image.

flat is a good idea with a full disk with zwo178mm because : viewtopic.php?t=20973

halpha sun on March 9th

good morning, everyone, the clouds came back late at night on the Albion plateau. I still managed to catch the sun in a very tiny lightening (before everything is gray!) (single 17s video! viva the 60img/s of the 178mm... and the SSD!)...)... as much to say that about the setting, there is only the ...

Re: halpha sun on March 7th

thanks to you :)

@montana > yes, sun during the day and deep sky object at night... well, weather permitting! ;) It is to say if I do not sleep much sometimes when I am at the observatory! :D

halpha sun on March 8th

Good evening, everyone, still a little bit of sunshine today from the Albion plateau (it's likely to spoil from tomorrow :( ) but we had to juggle between clouds, cirrus and the late hour. at fs60 with the sm40 double stack, glasspath x1.25, BF10 and zwo178mm towards 15h10 UT http://www.astrosurf.co...

good morning, everyone, passing this week at the Sirene Observatory ( https://www.obs-sirene.com/ ) on the Albion plateau in France, I was hoping for a better weather forecast than at home... well, not really. http://www.astrosurf.com/ls35dx/new39/S20180307-matos.jpg After the rain and snow of the p...

sun halpha from february 28

Good evening, everyone, on vacation at the moment: still as cold but sunny today... for the moment, I tested the solar in nomad configuration with the fs60 on the staradventurer! :) It works, but it's not easy to do the MAP, it's not very stable ;) https://i.goopics.net/eL9A9.jpg the seeing was also...

Yes, with the small pixels of 178mm, the sun has a nice size!
some more problems with visible newton rings, next time I try without the glasspath (even if the sun will be smaller on the sensor ;) )

Good evening, everyone, a more transparent sky than yesterday... but a breezy and colder air! I always try to improve my flats at focus: transparent plastic bag in front of the sm40 for here. Works not too bad but not yet perfect... always at fs60 + sm40 double stack + glasspath x1.25 + BF10 + zwo17...

Good evening, everyone, It's not hot right now here in france but clear skies by my place this saturday... clear but not coronal! But still enough for me to draw the portrait of him on our solar star; even if his surface is very poor in activity. fs60 with its sm40 double stack, glasspath x1.25, BF1...

A frenchman in Oregon for the eclipse

Hello, Like some of my compatriots, I made the trip to the United States to observe this total eclipse of the sun (and incidentally do a 15 days road trip for a little tourism. https://www.google.com/maps/d/viewer?mid=1wJ2APwHxL30S5ADdh3kgg23-wA8&ll=38.74782135758403%2C-99.64599599999997&z=4 ).

sun halpha from december 16

Hi, I am new to this forum, also a short presentation: I am French (so sorry my poor level in English), and I have been watching the sun for many years. Sometimes with an astrosolar filter on a C8. But most often, in halpha. At first, with a lunt ls35dx; but now with a fs60 equipped with a SM40 doub...
