This image is 21.5 hr of OSC data through an L-eNhance filter. Complete equipment, acquisition and processing details with the image here:

This huge field of view is courtesy of a QHY367C camera on a Tak FSQ-106 at f/3.6. Full processing details with the link.

Very nice shots John! I am still acquiring on this object.

This expansive field of nebulosity shows the heart of Cygnus from the Crescent Nebula to the Tulip Nebula.

Gallery / IC 1396 Narrowband Colour
« on: 2019 August 12 18:10:26 »
This was imaged with a one-shot colour camera (QHY367C) and an Optolong L-eNhance filter. All pre- and post processing in PI, of course!

Division to remove multiplicative gradient (imperfect correction of flats, for example). Subtraction to remove additive gradients. I don't always use both; it depends on the image. Subtraction on its own can give a very nice result most of the time.

I continue to be impressed by both the Optolong L-eNhance filter and the QHY367C one-shot colour camera for this type of target.

Sure I definitely could and everything would probably work fine. TheSkyX has a version for the Raspberry PI, and all my equipment is controlled through TheSkyX. I also saw that QHY is coming out with a PC system for astronoimaging. I guess it is just a matter of preference (and budget, of course). I am also fortunate that PrimaLuceLabs gave me the Eagle 3 Pro to demo. Last, and probably least important since I can learn -- I still haven't jumped on the Raspberry PI or Linux bandwagon, and have enough steep learning curves at the moment!

Clear skies,

Gallery / Veil Nebula
« on: 2019 July 19 06:01:32 »
This is a first-light image for a new camera (QHY367C) and narrow band filter (Optolong L-eNhance) designed for one-shot colour cameras. The filter passes Ha, H-beta and O3. This image was acquired under intense moonlight, and I'd expect this filter to also perform well under light-polluted skies.

Looks like we might get a stretch of four clear, relatively moon-free nights next week! I will probably shoot some more in Cygnus, maybe around gamma-Cyg or the Crescent Nebula region where there is some nice O3 to be found.

Clear skies,

Our Chicago workshop is just weeks away, on August 3-4. Join us for 2 full days of hands-on image processing with me and Warren A. Keller, author of "Inside PixInsight."
Agenda and registration at https://www.ip4ap.com/Workshops/summer-2019-Chicago-workshop/ .

There is still time to get the early bird discount!

Gallery / Globular Cluster M5 and dozens of galaxies
« on: 2019 June 19 09:22:06 »
This is M5, one of my favourite globular clusters. This image also shows dozens of distant galaxies; some are shown on the included annotated image. This was the First Light image for the Eagle 3 Pro computer which controlled all the equipment. It performed flawlessly.

More equipment updates coming soon :-).
