drjolo Posted June 6, 2018 Share Posted June 6, 2018 I collected frames to the image below over a few nights in April and May this year after my regular sessions at my roll-off shed under suburban sky. Setup was: Meade ACF 10" with AP CCDT67 telecompressor, QHY163M camera with Baader filters and EQ6 mount. Seeing and transparency were usually average-good. It is HOLRGB composite: 3.5 hours of Ha, 2.5 hours of Oiii and about 2 hours with LRGB filters. Abell 61 planetary nebula is not often imaged target. It is quite faint and pretty old (about 22,000 years). Can be located in Cygnus and its apparent diameter is 3.3 arc minutes - more less the same as M97 Owl nebula. But Abell 61 is much fainter.

drjolo Posted June 7, 2018 Author Share Posted June 7, 2018 Thanks guys! As I have read later it is not so hard target, it is also available for visual with larger scopes. But under my light pollutes sky even with narrowband filters it was a challenge Link to comment Share on other sites More sharing options...

Yes, it is. Hot star with apparent brightness 17mag and effective temperature over 60,000K. Link to comment Share on other sites More sharing options...
