Arrived today from @FLO. Essential reading I'm told before I invest in some proper imaging kit.

Had (yet another) go at Pleiades this week. I upped the integration time (about 150x25s light frames) and used ISO 1600 instead of ISO 800. I also bought some step down filter rings off Aliexpress to get rid of the big diffraction spikes caused by the lens (thanks @alacantfor the suggestion). I have also invested in Photoshop and the Astronomy tools plug ins to help with processing. These are the final results, the first image being heavily cropped. Thanks again everyone for their suggestions and help on this thread. I am now saving up to buy a proper mount and telescope so I can improve my images further.

Third attempt at capturing M45. Combined some more data to the one above, and took a slightly different route while processing. Finding this hobby very addictive and rewarding

Hello everyone. After all the advice I received on this thread, I've managed to find a couple of hours of cloudless skies to try out this lens again. This time, I took some flat and dark flat frames (not that hard after all), and used some noise reduction plug ins for gimp. I also took more care when stretching the image, checking that the noise wasn't getting to bad as I went along. This is my new image of M45, which I think is a slight improvement on the one in the OP. Thanks again everyone for their tips and advice

This is very interesting and informative. I also noticed the notches on the diaphragm, wasn't sure if that was normal for vintage lenses, as this is the only one I've used. I also get red halos around bright stars when focusing, and like you, focus by making sure these disappear. I would definitely be interested in a vintage lens thread, as that's all I can afford for the time being

Thanks for your kind words. I would have been overjoyed with those images when starting a few months back, but I suppose you become more self critical as you gain some experience.

I bought this lens a few weeks ago. This is what I've managed with it so far. Don't be put off with these images though, as I'm a complete novice, and my processing skills aren't the best

Thanks for the advice. I will definitely look into some kind of mask to aid with focusing, as I must admit, there is some degree of guessing going on with my current approach. I've read that Y lord is maybe more suitable for dslr lenses, as they let more light in? They also look easier to make than a bahtinov mask(don't want to be spending more money at the minute)

That's also what I've found in the short time I've been using it

I've thought about making a Y lord mask, it might be worth a shot, and I will have a look at the videos you mentioned when I have time. I followed one of Serif's (I think) when trying to process andromeda a couple a months back. Regarding a dslr controller and android app, how would that aid focusing?(excuse my ignorance) Thanks again

At the minute, I'm focusing using live view at x10 magnification. I suppose a bahtinov mask would help?
