Re: Modified SM40 - A Story of Evolution...

Mark

it looks that the T-max adjuster is really difficult to unscrew from SM40. Is that normal? Should I try harder?

Yes, will just unscrew...

Re: Ha Full Disk - Sunday 26th Feb

Thanks guys! Hi Apollo, shooting through the haze / thin cloud definitely didn't help things - when I saw the histogram for the raw image it was all compressed - all the highlights were greyed out and skewed towards the mids, all the shadows were greyed out and skewed towards the mids. Stretching th...

Ha Full Disk - Sundays Sun 26th Feb

The sky kinda cleared yesterday afternoon - the eastern half of the sky (where the sun wasn't) was lovely and deep blue, however the western part of the sky was a thick milky haze. Took a while for me to wait just for it to become vaguely constant (if not good) transparency so I could get this imagi...

Is the etalon unscrewed from the black box using the boa constrictor / rubber strap tool then if it's a toughy to get out?

I struggle with colour vision myself too which is why I prefer monochrome. Nice image tho! How do you process them?

Looks good Andrea! I take it's pretty easy to unscrew the etalong assembly from the black box of the PST?

Re: Saturdays CaK Sun

Thanks Brian! :) Pedro, I don't think it would work using a Baader with ie. stacked with the lunt module - certainly if you do that with the coronado CaK PST it just makes the images dimmer - ie using the 2 complete filters in series. To make it work I had to replace the blocking filter part of the ...

( The reason I ask is the added significant cost of the Baader....) With 60mm etalons you consider this as a 'tester' to see if wort...

Thanks! :) My homebrew CaK filter has a tighter bandpass than the Lunts ;) 2.2a compared to the 2.4a of the lunt, makes the super granulation much easier to se...
