2012-10-20: The Sun in Ha and High Res

[nandopg]

Hello,

Some images I managed to capture before the clouds. The seeing was really bad (1.2-5) and the transparency during some images was also bad.

Image #1 is a low resolution full disc with the annotation of the ARs to make easy to identify them in the high res images.
Image # 2: AR11592
Image # 3: AR11593
Image # 4: AR11589
Image # 5: AR11596
Image # 6: AR11591
Image # 7: AR11589
Image # 8: Prominence on NW limb

Thanks for looking,

Fernando

I only wish I could get my focus as sharp as yours. What is your set up?

Hi Pete, thank you for the kind comments. My setup for solar high res imaging is an APO Explore Scientific 127mm f/7.5 + Ha filter 0.4A from Daystar + 3.5" Feather Touch Focuser controlled by a FBII unit(Electronic Focusing System). I think this focuser is the one that makes all the difference due to its accuracy. The rest of the setup is a DMK41AS and a TV PMx4. On the same mounting, an EQ-6, I have a Lunt 60mm with dual stacked etalon for low resolution imaging.
Please see the images of this setup.

Thanks for the view of your setup. I have the Feathertouch focuser on the Lunt 100 and am very impressed with it. I do not have an automated version (yet).I find they are that little more responsive for Solar as compared to the Moonlight.Which i have on a 127mm APO. As an aside I have a Meade 80mm APO with a single speed focuser(standard) and it works very well indeed.
