Explore Scientific 1.25" 2x Focal Extender (FE02-125)

Seems to be mechanically solid. Unfortunately I am still waiting for a clear night to properly evaluate it. That's astronomy for you!

Buckeye TriBahtinov Isolation Masks for Focus and Collimation

mike obrien

Nice product

Nice product, I hope it works for me. I put the tri-baht together properly, it snaps together easily. Problem, it does not fit my 11” Celestron cat. The hole in the center is too small by a millimetre so the tri-baht will not attach securely. Any suggestions?

Hi Mike, thanks for the detailed feedback, and sorry the mask isn’t securing properly on your 11” Celestron. Please contact us with your exact telescope model. What is your C11 version. Classic, Edge HD? This is probably why it does not work.

ASTRONOMIK MC CLEAR FILTER 2’’ SCT 24 TPI Se visse directement sur l’adaptateur 2’’ SCT 24 TPI

ASTRONOMIK MC CLEAR FILTER 2’’ SCT 24 TPI

Se visse directement sur l’adaptateur 2’’ SCT 24 TPI , votre dos visuel se visse sur le ASTRONOMIK MC CLEAR FILTER 2’’ SCT 24 TPI.

1) Permet de sceller le tube optique. Une touche de graisse de silicone pure, de qualité, celle pour les équipements de plongée assure l’étanchéité.

2) Empêche les contaminants de s’infiltrer

3) Empêche l’effet cheminée lorsqu’on change un oculaire ou un accessoire par temps froids.

4) Combiné à une isolation thermique de l'OTA un isolant thermique à double face genre REFLECTIX, permet de sortir l’instrument d’un local chauffé vers la température frigide extérieure pour observer immédiatement sans attendre l’équilibrage des températures.

J’ai testé de 25C à 5C, sur deux nuits à l’oculaire clavé 10mm dès l’installation 5 minutes après la sortie de l’instrument, l’image est absolument nette avec seulement la turbulence d’un seeing de 3-4, et ce durant toute la durée de la séance.

Images de Saturne au MK127 de SVBONY F:1500mm, Caméra ZWO ASI 678MC au foyer primaire, Filtre 1.25" Baader contrast boost, capture .SER, Sharpcap, PIPP, AS4!, registax 6.

Les photos sont un stack des images brutes stabilisé de PIPP, et l'autre un léger traitement dans Registax 6.

Le 27 octobre vers 21h30 5 à 10 minutes après avoir sorti l’instrument, viewing 3/5. Hier avec barlow QT 2,25x Baader, résultat similaire. C'est ce que j'espérait, les tests se poursuivre.
