+Graham Posted May 5, 2015 Share Posted May 5, 2015 Well thanks to Steve I can finally use the 916 with Maxim. It was a mad rush after getting home from work. Had to grab this between the clouds so the focus is a bit soft. GT81 Home made Thousand Oaks Solar filter. HA filter. 22 Subs at 0.005 seconds. Collected in Maxim Stacked in Maxim Coloured in PS 6.

BAZ Posted May 5, 2015 Share Posted May 5, 2015 When you get a bit more time that will turn out great. Link to comment Share on other sites More sharing options...
Perkil8r Posted May 5, 2015 Share Posted May 5, 2015 Nice start. Can I ask why you use the Ha filter? Link to comment Share on other sites More sharing options...

Thanks Baz It was all done in a rush what with the clouds and the fact that the sun was disappearing below the tree line. Nice start. Can I ask why you use the Ha filter? I have no idea Mike it just seems the logical thing to use seeing the sun is HA Link to comment Share on other sites More sharing options...
Perkil8r Posted May 5, 2015 Share Posted May 5, 2015 Ah, I see.... Whilst that is true, a normal imaging Ha filter has a bandpass of 7nm whereas a Ha solar scope has a bandpass of 0.07nm or less. To be honest using a Ha filter for solar is likely to cause you more issues than it is worth since it is 100 times wider bandpass than you need to pull any more detail. I'd have a go without and see if it makes focusing a bit easier for you Link to comment Share on other sites More sharing options...
