Whole disk w 0.5x reducer

[vineyard]

I took a punt on an Antares 0.5x reducer to try & get whole disk solar.  (My normal set-up is ASI290MM on a 480mm f/l w 50mm etalon & that doesn't give whole disk).

Happy to say it worked!  So no need to change cameras to 178MM or 174MM (& heck of a lot cheaper too!).

Here's a quick whole disk.  The 2nd image is an ROI - strictly I should compare the same ROI w just the ASI290MM native & then w the reducer.  Will try that in the future, but it's not a hardship to just put the reducer on for whole disk & then take it off for ROI
