Lobster and cat's paw in a bottle 6 sky, Fuji X-T4 unmodified

I am an amateur astro photographer, feedback is gold !

Photographed with a Fuji X-T4 (unmodified), total of 90 min exposure time, Skywatcher star adventurer with auto guiding

Photographed form a bottle 6 sky near Sydney

That is an excellent image for an unmodified camera. XT4 has the same sensor as these ASI2600mc astro cameras which are also proving to be very sensitive to HAlpha light.

I had an XT2 and it gave quite good Ha response as well. A bit of a Fuji trait.

Which lens/scope was this? It looks to be about 300mm in focal length.

Cheers Greg,
This was with. WO Z61.

I was surprised with Fuji's performance as well. Im still looking for a solution to use my computer to shoot combined with PHD dithering. It would have been great if they had more application support like Canon or Nikon does.

Very Nice Hashanr

Greg is correct (Hi Greg), the Fuji cameras have excellent Ha response for an unmodified camera. I don't know if it applies to all the Fujis, but I imagine it might and have seen Spectral transmission data for the Fuji XPro1 /XE1 UV/IR filter which shows something like 45% transmission around the Hydrogen Alpha 650-ish nm region, compared with typical unmodified Nikon, Canon and Sony cameras in ~20-25% transmission range. That's nearly double the amount of light in the Hydrogen Alpha region from a standard camera and compares favourably with modified cameras in the 60-70% range. Early on I bought a couple of XE1 cameras to test, but that's a job still on the to do list, as I prefer fullframe and the early Fujis had limited tethering capabilities. Still having said that the improved Fuji Hydrogen Alpha response in their early APSc cameras is so good it almost bridges the difference in the light collected between APSc and Full frame in the Ha region.

A great field and equipment combination that shows much promise.
