The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:
Having upgraded from canon 1000D to Nikon D5300 how do users of the 5300 find it for Astro I will be using with APT , and how do you take flats as I can’t use Av mode as there is nothing in tools menu to choose no lens , do you use in manual mode and look at histogram ? .
I just try to show the beauty of the night sky, and again the possibilities with a smartphone. There are already better applications at the google play to make the night lapse easy. At first I used the Gif maker pro. It's a good app to edit the frames, before creating video, but you can't save the videos in good quality. Now I use the TimeLab app (same developer, as Intervalometer app), in the editing it has not so many options, but with this app you can save the videos in 4K too, or full HD. This video is 360 frames (each 30 sec exposition at ISO 800) Huawei P10 monochrome camera, Intervalometer app, TimeLab app. Pictures taken in Kleinwalsertal, Austria 2019. 09. 23-24. (The video is full HD, I don't know, why, but it doesn't run continuesly on my PC, when I watch that back on SGL. I hope, on your monitors you can enjoy it!)
I spend a day here to analyze my master flats and what vignetting I have on my lenses and telescopes. It's very simple done but still interesting to set figures on it.
It's done on a full frame camera and I use the values from the center and the corner of the sensor. The corner is 22 mm of from the center on a full frame sensor. I never liked to have strong vignetting in my optics, and in the future I want to go for bigger size than full frame.
I have put together a page over the vignetting I got:
Maybe interesting for some of you to have a look at.
My telescope shall handle a medium format sensor of the size 48 x 36 mm with the setup I have now. My medium format optics already do it. Just missing the medium format camera.
