#LunarOccultation of #27Leonis 25/04/26. #WilliamOptics 70mm refractor + #ZWO #ASI120MC camera. The star vanished at 20:26:28 UT / 21:26:28 BST. I missed the moment it reappeared because of the huge magnitude difference, and I had the settings wrong Oxfordshire, UK
On 25th Feb '26 I photographed the #EyesOfClavius #ClairObscur effect. This animation shows how much the Sun had risen over #Clavius between 18:01 and 19:40UT. #WilliamOptics 70mm refractor, #ZWO #ASI120MC camera, #Televue #Powermate5x. #Oxfordshire, UK
Lunar images I took on 25 Feb '26 when the Moon was 64% #WaxingGibbous. I love this lunar phase because the lighting is great over so many of my favourite regions. #WilliamOptics 70mm #refractor, #ZWO #ASI120MC camera + #Televue #Powermate 5x. #Oxfordshire, UK
Yesterday was the 5 year anniversary of capturing this #InternationalSpaceStation #LunarTransit. We were in lockdown at the time but our house was below the transit centre-line & the #ISS passed over #Copernicus #WilliamOptics 70mm refractor #ZWO #ASI120MC camera. #Oxfordshire UK

雨が降っているので、分かるヒトだけ分かる話。
妄想オーストラリアリベンジの機材準備。
FL55SSの鏡筒径は80mm。これは手持ちのFS60QやRedcat51と同じで、バンド・キャップなど共用できて便利、、、、続く #FL55SS #Vixen #ビクセン #williamOptics #天体観測

今年はまだDWARFでしか撮影していませんが、去年RedCat51ⅡとASI294MC PROで撮影した総露光17時間分を一から再編集してみた。

午前2時半から先日購入したMINICAT51のファーストライト。モノはIC2177：通称かもめ星雲。
MINICATはfl:178mmと撮像素子の小さなASI533で広がった対象を撮るには手頃な焦点距離です。、、、続く #かもめ星雲 #MINICAT51 #WilliamOptics #ASI533MC
