Last night turned out to be better than forecast, so I wanted to share some images I captured while broadcasting on NSN.  Using my C8 @ f4.3, a MallinCam Xtreme X2, Idas LPS filter with no post processing.

This one I deliberately rotated so the face in the nebulosity is more apparent.

Thanks for posting some colour Don.  I enjoyed these live on Don's NSN broadcast.  I much prefer colour over mono which seems to be the latest "thing".

Pluto from last night.   Same setup as before:
CPC11 @ ~F3.7 Lumicon DS, 30s exposure, no stacking  MCX icx 418 class 0 sensor

 

Annotated.   I was surprised that I also captured a small Asteroid in the frame (Memoria 1247)...  fun!

Whats really great is we are able to get to over Mag 15 with just 30s exposure at (AGC4) shooting through the muck at this low elevation and with a filter!

Excellent images, Don.  I really love the colors in the Veil.  The Bubble is a tough one.  I keep trying to get the ideal Bubble, but just haven't gotten it yet.  Maybe you should try  a NB Ha filter.  Chris A gets a good one with his Xtreme and Xterminator, but they're mono.

Al, really do like the gif you made of the comet, maybe you can follow up in a few nights or a week or so with the Pluto observation.

Thanks Dwight  and Don for your kind words.  I also like color but mono is very interesting also and many a broadcast I will click on the grey scale option just to get a different perspective.

 

I do NB Ha infrequently and prefer not to do it with the color camera, I used my SC3 when I had it and primarily imaged during the full moon.

 

Here are a few SC3 10nm Ha shots, those that are dated 10/8/14 thru 2/6/15:

SX-825 with LodestarLive

 

Below I am posting a few captures made with the SX-825 mono camera and LodestarLive software. At full resolution, which I am using, the SX-825 produces near HD images. But their size exceeds CN file size limitations. For this reason all images posted here are reduced to less then their original size and resolution. This, of course, takes away the advantage of HD. After each image I provide external links to the full size captures and strongly recommend viewers to check them out.

 

Please post any questions, comments or other verbal input on the discussion thread http://www.cloudynig...le-and-working/ to keep this gallery thread for images.

Live Stacking with ASI224

 

Some images from last night using ZWO's ASI224 camera. Taken from my backyard looking towards San Diego downtown - heavy light pollution, cannot see stars fainter than mag 3 (Sagittarius is about 25deg above the horizon for me).

 

Setup used: Nexstar 8SE running at ~f/3.7, ASI224 color CMOS based camera and DSS Live.

 

Since I could not find a way of calibrating in DSS Live, these images are uncalibrated but with basic stretching only using DSS Live controls. Calibrated and processed versions (with additional subs) of these images can be found in this thread in the CCD forum: http://www.cloudynig...o-alt-az-mount/

 

The only negative I can spot with this camera is the amp glow otherwise it has very high sensitivity especially in the IR WLs.

Cheap EAA

 

I bought a Mallincam SkyRaider AGm camera ($200 USD) a little while ago to use as an all around video unit (as a guider, for collimation, solar system imager, and maybe a little EAA style viewing). The idea was to replace a few old CCD and webcams with one up to date unit.

 

The little camera has certainly pleasantly surprised me in it's EAA capabilities. For the record for EAA work I normally like to use my real video camera (an Xtreme) with raw analog video (to a video monitor), no computer enhancements. The AG is obviously a USB camera so it has to be connected to a PC.

 

For fun I tried the AGm in place of the Xtreme. These shots were taken with a C11 at f3.3 (Meade reducer) and the gain at 7.5 (3/4 of the limit). They are single 30 second exposures with no filters and no additional processing (the dark field correction capability was enabled in the MallincamSky software the histogram was adjusted and they were converted to JPEG). My skies last night were just better than mag 5 and temperatures were in the low teens C (mid 50s F). Targets were the usual summer suspects M57, M27, M16, and M17.

 

Edit: corrected to indicate that NO filters were used.

I'm pretty amazed with these snapshots given the equipment used:

- LN300 PAL 

- "Auto Settings" with x512 and x1024

- Astronomik 12nm H-a Filter

- Orion ST80

- "Chinese" Reducer

- Celestron Nexstar Evolution mount.

 

One thing: the LN300 would not come to focus with the chinese reducer with the supplied nose piece. I was able to get it come to focus by using a shorter, 20mm nose piece.

Had my first light with my AVS APU-1 on Sunday night.  I have a lot to learn, but here are my first images.  No processing just converted from TIFF to samll jpegs for uploading here.  They did not come out to bad.  This was on my C9.25 at F3.8 using a UHC filter

Jon,

 

I'm pretty amazed too ... those are exceptional images for the LN300. I honestly didn't think that images like that were possible using a camera with the limited exposure length capability and the 12nm Ha filter. Great job.

 

Now I think I'll have to look at Ha filters again ... sigh.

I'm planning on trying the same test with the Mallincam AGm very soon... Watch this space.
