Asteroid video

http://jeffjastro.com
Hi all - During a session earlier this year, I picked up an asteroid that was only discovered a few years ago (video of what I picked up is below). I was using the TOA-130F telescope. In the past, I picked up one only *2 weeks* after it was first discovered. Close! In any case, I certainly enjoy the science side. :)

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):
