In a nutshell Scientists identified over 500 planetary nebulae in the Sculptor galaxy, 20 times more than previous surveys, using the MUSE instrument, but the distance estimate they produced was ...

To help Joe Public make sense of this 1.5TB data deluge, COSMOS-Web has thoughtfully provided a full aperture and model-based photometric catalog. Using this reference, those interested can ...

Rectangular aperture sometimes produces the incorrect number of pixels in the photometry aperture. I believe this is actually a bug in astropy since the elliptical aperture does not suffer from this ...

Refeyn has announced that mass photometry has been recognized by the US Pharmacopeia (USP) – and referenced in the new draft USP general chapter <1067> – as a key orthogonal method for characterizing ...

A 1.4x teleconverter will reduce the maximum aperture of the lens by a full f-stop, while a 2x teleconverter cuts it by two full stops. So if you have a 300mm f/2.8 lens, adding a 1.4x converter will ...

Automated mass photometry combines the ease and efficiency of automation with the unmatched sensitivity and simplicity of Refeyn’s molecular mass measurement technology. The TwoMP Auto mass photometer ...

Synthetic Aperture Radar (SAR) imaging is a powerful technique for Earth observation, yet its efficacy can be substantially compromised by ionospheric effects. Variations in the ionospheric ...

The lens includes a tripod collar and foot, a lens hood and offers a constant f/5.6 maximum aperture. Performance: In our Nikkor AF-S 200-500mm f/5.6E ED VR lens review, we were impressed by the ...

Supervised machine learning predicts 1.57 million quasar redshifts from Gaia Data Release 3 photometry and astrometry, providing a new observational test of the cosmological principle.

We have rounded up the best lenses for astrophotography so you can capture detailed night sky objects and there are savings on the horizon with Prime Day coming on July 8!

Coded aperture imaging is a technology that capture the object image coded with a binary black and white coding pattern inserted between the object and the camera (Fig. 1).
