SGL 2021 Analemma Challenge Special!
Montana replied to MartinB's topic in SGL Challenges and Competitions
I'm not sure if this counts but I did an analemma from my back garden but it took me years to complete due to cloudy weather. You have to be absolutely on the second accurate and if the Sun doesn't shine you have to wait for another year, it takes ages! I took this over a period of mainly 2016 and then 2017,18 and 19 to fill the gaps. I used the location of my image as the backdrop, I didn't know I could go elsewhere to super-impose it. The image is therefore the genuine view. here are the links, they were all taken at 11:00 GMT Alexandra- 25 replies

Thanks, that works. That makes no sense? I check all programs as run as administrator as default. For Firecapture if you don't, none of the settings are saved, Autostakkert also won't run unless run as administrator. So for this program it won't work if you are running as administrator. I'm lost. But, thanks a million, it works!! Alexandra

I was wondering if anyone could help me solve this. I have used Deep Sky stacker for many years with no problems. Recently my computer died after a Dell Bios update. Dell replaced the motherboard and Itel graphics card but as a result everything was wiped clean. I have reinstalled all my programs so far but Deep Sky Stacker refuses to work. I installed the latest version 4.2.6. Set as run as administrator. The program opens fine, I load all my images in, check all, register checked images. When I press go the program immediately closes. I checked my Bitdefender and the permissions are set to allow it to run. I have reinstalled a couple of times and it still instantly shuts down when you press go. Have I missed something, I don't know where to go from here. Many thanks for your help Alexandra

Fabulous Ken, thanks for the link! I need a good read of this to see whether I would be intelligent enough to do this. I'm not very good at making things (failed completely with the PST mod) Alexandra

Wow!! absolutely phenomenal Alexandra

The tighter your bandwidth in the K line the more the filaments will stand out in CaK. If you look at spectroheliograph images in CaK, the filaments stand out as distinct black lines similar to Halpha. They are lines of neutral magnetic field. We can usually never see them as the Lunt and Coronado CaK are not narrow enough. You are obviously getting (but not quite) towards the optimum narrow bandwidth. You should build a spectroheliograph Alexandra

Absolutely stunning, well done Alexandra

Apollo, you have the best CaK animations in the world It is great to see everyone's best ever, together. They don't come about every year but these are my best two Can't post BB code or html doesn't work. What has changed? https://live.staticflickr.com/65535/50326981643_249b849d06_b.jpg https://live.staticflickr.com/567/21901673958_5a6989e784_b.jpg BB code used to work and was so simple. I have tried every link from Flickr possible and nothing works anymore. Pity. How Rusted? please do share Alexandra -

First, well done on the Solarcan, it is always so exciting to break it open and see the paper with lines on. Second, don't angle the next one keep it straight. This is a camera obscura https://en.wikipedia.org/wiki/Camera_obscura Therefore, the image is produced upside down. So to raise the height of your solar tracks you need to maintain the can in a straight position but you must move the pin hole upwards. I tried this this year and managed to get more tracks but still not high enough. I made my hole exactly half way between the middle and the top. I tried to get it higher but couldn't get the pin through, I think maybe I hit a fixture inside. I need to try again and get higher. Try to understand the wiki post and you will understand what I mean. I also got the star reflections with mine using the middle provided pin hole so I think it is something to with the set up. I didn't get it this year with my own pinhole.
