Cygnus Loop

Hello, the tilt is curved.

And how is this treated? It's due to micro-play in the bayonet mount, as I understand. I'm just considering such a combo with the 533 MC. Are there tilt adjusters on marketplaces—have you come across any?

There is play in the lens block, and it is not easily fixable. I do not recommend a color camera; with lenses, monochrome is preferable.

Why isn't a color lens suitable? What are the advantages of a monochrome?

Lenses are not designed for night sky photography and do not focus colors like telescopes do. The channels will be out of focus — one in focus, two not so much — so you have to photograph the channels separately. The aperture also produces diffraction spikes. A lens is a compromise, especially with color. I got rid of the setup and am saving up for 2600mm; in terms of field of view, with my Askar it will be almost the same as the 585 and 135mm Samyang, but without the hassle.

Thank you, there's something to think about now :-|

Again, focusing is manual, or you can rig up a strap-based mount. The lens has a shallow depth of field. In general, you could try something from Soviet optics, like the Jupiter 37, to get a feel for it. Cheap and effective.

Jupiter is done. Out of curiosity, I'll compare them, of course. It's just that my setup is tuned for Samyang — rings, mounting plates, and other accessories.

Well, give it a try — you can always sell it. Some people get really great results with lenses, so maybe that's your path. I've put that topic aside for now. If I ever go monochrome, I might try again — I kept the accessories and adapters. I recommend getting a Canon mount — it's wider and not as flimsy as Nikon.

It's late — I already have a Samyang for Nikon. I should have switched earlier, but now it's too late. Everything is built around Nikon: adapters, lenses, two DSLRs.
