Wow, these are awesome! Especially the first and last ones! Is the last a mosaic?
ReplyDeleteThe last one is a single image. It was taken with the ST80 using the full-spectrum solar filter. It is composed of 51 stacked exposures of 1/3200 second each.
ReplyDeleteIt's very nicely done. What setup do you plan to use for the transit?
ReplyDeleteI will be using the Canon EOS Rebel XS (1000D) on the Orion ShortTube 80 with a full-spectrum solar filter, and a Meade DSI mounted on a Coronado PST via a 2X Barlow. The PST will be mounted piggyback on the ST80. Both scopes will be on the Vixen Super Polaris mount. I'll try to post a pic of the setup soon.
