First (white) light with 180 Mak

[gabrieli]

I've seen some promising results with this scope to know that with improved seeing, it's a competent device for Ha.
I didn't have a full aperture white light filter for this Mak until recently and so I was anxious to try it out. Limited moments of seeing had to be accessed between passing clouds so that the number of frames was well below 1000.

I mounted Baader 3.8 solar film on an unused filter cell that happened to fit the front of the scope with a 2X Powermate and also a 2.5X OPT Barlow. I tried a 2.5X Powermate but that resulted in the common "doughnut" ghost right in the live view. For further filtering, I tried a Baader 610 nm filter, an Astronomik 642 nm filter, and a Baader SulphurII 673 nm filter. The best calming effect happened with the darkest filter - the Sulphur II. For the amplification and the moderate seeing present, I was happy with the results and look forward to bigger sunspots.

You have a considerable amount of detail here. I would be very satisfied with these!

Fabulous WL Lou to cure the TeleVue 2.5x powermate problem you have to add an extra 4cm between the powermate and your camera, it then works a treat

Thanks for the comments and views and, Alexandra, thank you for passing on your solution to the Powermate "doughnut" problem. I can hardly wait to try it out.
