Yesterday (March 19) I managed to take out my TV Pronto, the PVS-7 and some new equipment I just got to try some NV photography. Main objectives were to test the combination of the inexpensive, used 2" Orion 50mm Plossl eyepiece that I bought on the CN Classifieds, connected with a Novagrade afocal adapter to the original Envis objective of my PVS-7.
For details on the adapter, see cnoct's page (I will also post soon some details) https://www.cloudyni...r-nv-astronomy/
A few disclaimers: I never tried before the above equipment, and only very marginally used the Pro mode of my Galaxy S9. In addition, the cell phone adapter that I have does not line up properly the camera with the PVS-7 ocular, nor does it keep the phone perpendicular. A better one on its way from ModArmory.
The tree canopy in my yard leaves few open spaces but I found the Pinwheel Cluster Messier 36 (discovered however by Giovanni Battista Hodierna) to be in sight. Strong moonlight from the SE, no breeze. Visually with my Nagler 20mm I could faintly see a fuzz.
See below single-exposure pics of the PVS-7 screen, which are quite close to real time views.
General impressions: the Novagrade adapter is easy to use and it provides a reasonably strong attachment of the PVS-7 to the eyepiece. I like a lot the idea to try afocal pics with a variety of EPs of my choice. I connected the PVS-7 to a 1.25" 40mm EP by changing the Novagrade compression ring size, and it was fast and easy.
The ENVIS lens seems sharp in the center but it has a lot of distortion elsewhere. I plan to see if I can modify the rig to use my Pentax camera lenses instead.
The middle-level tube of my PVS-7 seems still more than enough for where I am now along the learning curve.
