Here is my first ever color image of M57 using an Astro Video Systems DSO-S video camera. I used a focal reducer .5 for the first image at Intmul 5. I removed the reducer for the second image at Intmul 5.

Hi All,

 

Had some clear skies last night, so I thought I would try my NB Ha filter in the Lodestar X2c.  Because of the Bayer mask and the Narrow band Ha being in the red part of the spectrum, resolution is lost with the X2c.  But, as Dom has shown in the past, the results are still quite pleasing and interesting.  Another thing the NB Ha filter does is to block all unwanted light, even the moon, improving contrast and reducing star bloat significantly.  Those with LP should definitely try one of these.  They do only work on emission nebulae, but there are a lot out there.

 

All these captures were made during my viewing session last night.  All adjustments and stacking were done on the fly with Lodestar Live v0.12, Paul's latest release.  Other than resizing for CN download, there was no post processing.  Scope was a Meade 8" SCT at F3.7.  Object name, exposure times and stacking are given on each image frame.

From under the hazy skies of Seattle and heavy daytime work load I cannot compete with Don's excellent images and productivity. Nevertheless, I post the meager result of the first two hours of star watching since my previous post http://www.cloudynig...lery/?p=6601977 in May. This is to heed my own words that an image is worth more than thousands of words and, I hope, may inspire more forum members to post images. Even if they were made under less than ideal conditions.

 

This is a narrowband OIII + H-alpha image of the Dumbbell Nebula M27 taken with my Lodestar X2C and LodestarLive v.0.11 through the haze, high clouds and light pollution of the Seattle skies at 3/4 full moon.

It was a day of hazy sunshine and, when it got dark enough at 10:30pm to align my mount, only about 50 of the brightest stars were visible to the naked eye. So I live-stacked (using averaging) six 20 sec frames in LodestarLive. This is the double of the three that I usually mean-stack. Still, at full resolution, the noise resulting from the poor transparency of the air is still visible. I manually adjusted the contrast of the three color channels to keep the red of the H-alpha from overwhelming the more subtle teal of the Oxygen III, which I like. (I can provide images with more red for those, who prefer that.) This also keeps the central star faintly but still visible.

 

The telescope used was a Meade 10" SCT focally reduced to about f/4. The only difference to the setup that I posted last year http://www.cloudynig...etup/?p=6210387 is an added filter drawer between the flip mirror and the camera.

 

The careful observer can notice the path of a single hot pixel just above the "FL1000mm" subscript. This corresponds to the drift of the imperfectly aligned mount from the ideal during the total of 2 minutes that it took to capture the six frames. This connects to Nytecam's thread http://www.cloudynig...-imaging-works/ on drift scan imaging and illustrates how state-of-the-art software can compensate for shortcomings of the mechanics of a setup. Without the excellent frame alignment routine built into LodestarLive all stars would have the same lengths of trails and the nebula would be a barely recognizable blur.

 

Clear Skies!

--Dom

Dom,

 

That's a great image from under what most of us would consider not just tough but impossible conditions.

Hi folks. I am a new Lodestar X2-Mono and X2-Color owner and these are some of my newbie first light Lodestar Live images from last evening with the X2-C and a C80ED f/7.5 refractor. Skies were hazy and the moon was up in the East. I still have lots to learn! Not sure what I did wrong on M19, no color at all!
