Confirm atingerea focusului si lipsa aberatiilor cromatice in configuratia :

Oculare :
1.25"   Plossl  6 mm GSO
1.25"   8 mm BST Starguider ED      Imagine foarte clara a lunii fara aberatii cromatice
1.25"   3.2 mm BST StarGuider ED   Imagine foarte clara a lunii fara aberatii cromatice
GSO Barlow lens 2,5x APO / 1,25'' + 1.25"   Plossl  6 mm GSO  / lipsa aberatii cromatice la ~ x175 
2"        SW APEX 28mm (Kellner)   - a fost o plimbare de vis printre stele cu acest ocular

Daca nu se vrea folosirea diagonalei se poate folosi :
 SW APEX 28mm (Kellner) +  80mm Extending adaptor with 2" internal filter threads 50.8mm

Pentru ASTROFOTO :

OVL Field Flattener + Bayonett adaptor T2 (internal thread) to Canon EOS 

sau fara Flattener

Adaptor 2" la T2  cu lungimea de 40mm + Bayonett adaptor T2
