Baader Herschel prism – UV solar imaging

I did do some UV solar imaging with the Baader Solar film previously. Unfortunately, the one Solar film I have is for solar viewing (not the photographic version), which does reduce the light passing through to the camera significantly. Hence I have had to use higher ISOs and slower speeds for imaging when using the Baader U. Hence I thought it would be good to try this again now that I have the Baader Herschel prism, to see if enough UV is passed through to the sensor.

Baader Herschel Prism – single vs double stacked Solar continuum

For this post, I would like to compare the difference in images between the use of a single Solar continuum and double-stacking. In my previous test, I did not find that much difference between those images with and without IR, hence I wanted to know if there was any benefit from using a double-stack of Baader Solar continuum (as I have two of these filters in 2″).

Baader Herschel prism – Solar continuum with and without IR-cut

For this test, I have taken images with two different cameras. I have used the full-spectrum Olympus E-PL5 with the Baader Solar continuum and ND 3.0 filter for the images without IR-blocking, and the unmodded Olympus E-P5  with these two filters for the system with IR-cut. The question is whether there is any detectable difference between the images taken. Continue reading Baader Herschel prism РSolar continuum with and without IR-cut

Baader Herschel Prism – unboxing

I have been thinking of buying a Baader Herschel Prism for many years now, as this has been described as the best herschel prism available. My main interest with this would be for solar imaging, although it would be very good for solar viewing as well. Unfortunately the cost has always been fairly high, and it just never made it up the priority list. Continue reading Baader Herschel Prism – unboxing

Sony NEX-5N vs Olympus OM-D EM-5 UV imaging

In this post, I will be doing a side by side comparison of these two cameras, with regards to the cameras themselves, ease of use, functionality and image quality, as well as images from both cameras for comparison. I know that there are features in both cameras which I like, and it would be great to see them all amalgamated together into one camera (although this is unlikely to happen).

Sony 20mm F2.8 – UV test

I bought the Sony 20mm F2.8 E-mount pancake lens mainly to test it for its capability in shooting UV and Insect-D-sight, as it is small, light, fairly wide-angle and a native E-mount lens with autofocus. I previously owned the Sony 16mm F2.8 lens, but sold it even though it transmits UV reasonably well as I did not like the image quality. I was hoping this lens could perform similarly well in UV transmission but with better IQ. For this test, I used my friend’s NEX-5N.¬† Continue reading Sony 20mm F2.8 – UV test

Sony NEX-5N – UV imaging

I remember few years ago when i first owned the Sony NEX-3 and used it for UV-imaging. Unfortunately the custom white balance range was not sufficient to properly white balance in UV for the jpeg files. This issue was fortunately resolved by the NEX-5N (4th camera in the NEX range) which had a wider white balancing range. I had sold my NEX-5N a while ago, and hence could not test this again until I borrowed my friend’s copy. Continue reading Sony NEX-5N – UV imaging

Thunderbolt SSD Drive

Since starting my website, I have realised that the Western Digital My Passport 2TB USB 3.0 drive is not really keeping up the large RAW files that I have in my Capture One Pro catalog. Even browsing the thumbnails can take quite a bit of time as there is significant lag while these load up. Hence I decided to invest in faster storage, to improve computer efficiency.
