The Orion Nebula from a Bortle 7 Red Zone

I was doing a shakedown of new equipment and decided to post the results of my test shot of the Orion Nebula.  The 11 sub-images were taken from a red zone on the LP map, probably a Bortle 7 to 8 sky with only the brightest stars visible.

I was trying out a freshly configured Windows 10 laptop, a new guiding camera and a new guide scope.   Yep, I broke down and bought the new Orion Ultra-Mini guide scope, since it matched with my relatively new Aptina AR0130 color planetary/guider cam.    I also used a new Shoestring Bluetooth wireless interface for the mount, which although it worked well enough towards the end, the first part of the session was not without issues.

This session was also the first one where everything actually worked since I replaced the two stepper motors in my Atlas mount.  The last time I tried it I couldn’t get the little netbook I was using to stay connected  to the mount.  A different laptop with a more robust USB bus did the trick.

There are still kinks to work out with the new guiding camera arrangement and the newest version PHD2 Guiding.  The last time I used PHD Guiding, it was Craig Stark’s original version.  This is the first time I’ve used the new Open Source version.   It will take time, but I’m sure the setup is capable of getting the job done.   I got rid of the Meade SN-6 scope I was using as a guide scope and that reduced the weight and bulk of the imaging rig.   A lighter payload should let me get better tracking once I have all the settings tuned, hopefully.

I’ve gotten behind in the last couple of years and now I can finally catch back up to all the new technology and software that is now available.    Soon, I hope to transport my revamped imaging rig to a dark sky sight and churn out some new keeper comet and deep sky images before summer arrives.   Wish me luck.  🙂

M42 with a Dobsonian – No Tracking

Orion Nebula Core Area. 32 frames, 350ms, Aptina AR0130 Color Imager/Guider, 6" F/8 Newtonian, Dobsonian mount.
Orion Nebula Core Area. 32 frames, 350ms each frame, taken with an Aptina AR0130 Color Imager/Guider camera and a 6″ F/8 Newtonian on a Dobsonian mount.

Here’s one for the personal record book – shooting the Orion Nebula with a scope that has no tracking whatsoever.  It was on a Dobsonian mount.

I used an eyepiece camera in video mode and just let M42 drift through the field while I tried to get the most video frames possible.   I think I got between 35 and 70 frames for each video.  Out of 8 or 9 videos taken, two of the AVI files were good enough to try stacking select frames for a better image.

I used 16 frames from one video and 16 from another video.  Each set was stacked in IRIS with the planetary work process for AVI videos, then the two images were combined in PS.

The results are poor compared to what is possible with a tracking mount.  But, I knew it could be done with the right technique and I just had to try.   🙂

Lagoon & Trifid Nebulae Wide Field – Reworked

Here’s a rework of an image with data from higher resolution images overlayed on a base image that was taken with my 200mm F/2.8 Canon telephoto lens.   The overlay images were closeups of M8 and M20 taken with the TV-85 telescope.

A closer pairing of Comet Lovejoy and the Little Dumbbell Nebula on the night of Feb 20, 2015, plus another tail disruption event was in progress.

The last significant encounter with another Messier object for Comet Lovejoy Q2 before it dims down more and moonlight eventually spoils the view.   The best part of the apparition is about over.  From now on, the comet will get fainter as it recedes from Earth and heads back out into deep space.

Its has been a fun time imaging this bright comet over the last two months.   I had good public exposure with 2 news organizations publishing two of my images, one of them being NBCNews.com.   Hopefully, another bright comet will soon appear and put on another show for us.   I’m keeping my fingers crossed.   🙂

M78 Reflection Nebula in Orion

Good transparency and cold temps helps to get good images at ISO 800.  5 minutes subs are not too noisy and stack up nicely.   This image is only 110 minutes of integration and could use more time, but it came out fine for an unmodified camera.

The full size version is here.

Orion’s Belt Wide Field

It was very clear on this night at one point and Lovejoy had set, so I shot a few sub-images of Orion’s Belt to kill some time.  Although the Lumicon Deep Sky filter lets me go deep, brighter stars have ghost reflections off the filter and I had to clone them out.  There’s still a few remnants of them left.
