NGC 7000 area - 4-panel mosaic in H-alpha

http://jeffjastro.com
Hi all, here is my first mosaic that is larger than just 2 panels. This is a 4-panel and showing H-alpha data. This is using data from the years 2013, 2015, and 2017. Definitely check out the link for the full-size and many more details :)

First light image for new QSI camera!

http://jeffjastro.com
Hi all, I recently sold my QSI 540 camera and bought a new QSI 690! I replaced the 690 faceplate and filter wheel with that from my 540, thus I am keeping all of my original Astrodon filters, plus have the OAG port. So, my QSI is now a 690wsg. The camera is an upgrade from a 4MP to a 9MP chip, plus has smaller pixels on the CCD, a much better match for my scopes and after some tests, it is allowing higher resolution and a closer look (due to normally great seeing conditions where I live). Love the new camera.

This is one of the first light images from the camera - the Horsehead Nebula region (data collected on 12 and 15 Dec 2017):

Emission Nebula Discovery in Puppis (journal article)

http://jeffjastro.com
Hi all:  I put together an article to have a document in the public domain (beyond my website) regarding the HII emission area/object I discovered near M47 (described in detail on my main site). The peer-reviewed article I wrote has since been published online:

This is my very first attempt at imaging this particular object :) and I used the big scope (130mm aperture Takahashi refractor), shooting at max focal length possible for my current setup (1000mm).
