Full disc 02-10-2022

Hi, Here today's discs. In H-alpha there were two flaring spots and acording to Spaceweather it was about class C 7.89 but it was not disclosed which of both and at the moment there are some more flares to come. https://rainerehlert.com/00_SCHForum/2022/10/Mosaico_20221002_Ha_9Q_RE.jpg https://raine...

Excellent Ha image Rainer. You have probably mention this before but have I missed it, what setup you are using to capture you're Ha images? Also, are you still using the iOptron CEM120EC2 mounts ?

Hi, Got some Sun and here the discs. As always best seen in a new tab/window and then clicking on the image to open it to full size :bow2 Interesting was that the seeing in H-alpha was by far better then in white light and that is way I have such a bitten limb in white light ;) https://rainerehlert....

This one did not move the ground where I live. In the Map below you can see the seismic activity in Mexico. Yuu will find me in the center of the Map and you can see it is seldom.

Hi, I lived in Mexico City for about 25 years and used to feel earthquakes and then after moving to central Mexico, a place allegedly with no earthquake activity, well yesterday the strong 7.6 Richter scale earthquake at 18:05 UTC was felt in my Observatory.

Re: Question on capture settings

Hello Pupak, What camera is this and what is SW. I do not understand why imagers are still using 8 bit avi for capture. Unless you are capturing to display on a 1 inch screen for Twitter or something similar, it will be inadequate. Hi, I guess SW is software. BTW, most of the cameras we use are not...

Re: Question on capture settings

In SharpCap I aim for Gain no higher than 100. Preferably much less. I push the exposure as short as it will go. Though usually end up with 7ms for 88fps. 3ms improves highly mobile seeing conditions in my experience over 7 ms. Which needs much more Gain. I aim for a rather dull {dark] image on the...

Hi Warren, I do adjust is the exposure and only when I see that there are some crackling solar spots in order to not to overexpose them too much ...
