Nate Posted October 29, 2021 Share Posted October 29, 2021 Something showed up yesterday, just waiting on some adapters (Thanks Fandyus for the thread size). I'm guessing gold stays on the outside, and greenish on the inside. Thinking of how the James Webb Telescope will be used for IR and has gold mirrors. First tests showed exposure time dramatically decreased compared to my previous mix of filters, pretty excited. Link to comment

Kai Posted October 29, 2021 Share Posted October 29, 2021 Congratulations on the Baader-U :) Does anyone have a comparison of the versions (inc. Comparison images and recording dates)? Mine is from 2015 (yellow / pink) ... Link to comment
Doug A Posted October 29, 2021 Share Posted October 29, 2021 Congrats on the Baader. What filter stack is it replacing? Looking forward to seeing your photos. Thanks, Doug A. Link to comment

Thanks, Doug A. Thanks Doug. I had an Antilia venus that leaked way too much past 400nm so I put a few torch filters (claimed to be zwb2's) in the front. The Antilia blocked the ir really well, but it is a 1.25. So my whole stack was made of duct tape and plastic caps with way too many airgaps and internal reflections. But it got me into uv while I saved for the baader. Link to comment
Andy Perrin Posted October 30, 2021 Share Posted October 30, 2021 This is good. I still don’t have a Baader. I ended up with Schott UG11 and S8612 as my UV stack, with a lot of Omega and Thorlabs bandpass filters as backup. Link to comment

What'd that look like, a mostly UV image with violet in it? Link to comment

When I held the Antilia up to a regular light bulb I could see blue and purple visual, and pics where nothing like on here. When I put some torch filters in front, I had way too long exposure time and a greenish look to the foliage with proper white balance on plumbers tape. The strange thing I found after going out today with the baader on the 50-2, white balance on concrete forgot my w/b card, I still see the poo green. I screwed a zbw2 behind the baader and got worse. I still need to do more tests, but might need a deeper uv lens unprocessed convert to png, and resized baader only Link to comment

Yeah, I'm thinking my iso is causing issues, I used 1600 and it's a Canon T7 that's crappy with higher iso. My full spectrum 77D should show up within a couple days, and that's a bit better with everything. Hopefully it'll be sunny tomorrow to do some more tests. Link to comment

Maybe also I'm being too critical, trying to match the other baader shots on here with my equipment. I need to do more shots. Link to comment

Edit: I just realized you did post an image, you could post more but I think it looks completely fine. Link to comment

I just had color tone all messed up on my camera preset. Just tested both my 50mm's, and the Industar is great stopped down a bit. Link to comment
Kai Posted November 1, 2021 Share Posted November 1, 2021 ... that looks very good, Nate! Link to comment
Nate Posted November 1, 2021 Author Share Posted November 1, 2021 Thanks, I hopefully will go after some real targets soon Link to comment

You just have to turn the Hue color wheel around 130-170 °. https://www.ultravioletphotography.com/content/index.php?/topic/3176-kolomenskoye-park-moscow-russia/ https://www.ultravioletphotography.com/content/index.php?/topic/3075-south-west-of-france/ Link to comment

So much to play around with. Thanks for the Idea Link to comment
