Clever tube end covers for my non-standard home-built 10" Newtonian

Clever tube end covers for my non-standard home-built 10" Newtonian. Kind of like shower caps, but they are of heavy-duty material. I haven't yet tested them to see if they will keep out enough light to shoot dark flats, but I think they will be.

This is a great deep sky scope, and I am looking forward to getting some great pictures with it, all I need now are some clear skies (it's raining at the moment)

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.
