The Jellyfish Nebula

April 25, 2016

IC-443 (aka the Jellyfish Nebula) is the remnant of a supernova explosion in Gemini thought to gave taken place between 3,000 and 30,000 years ago and is approximately 5,000 light years from us. Though tough to spot visually except with large telescopes and very dark skies, it makes for a beautiful photo target. I combined this one in Registar using images taken with my TMB-92, AP-155 refractors and an older image taken with a C-11 HD. All were shot with a modified Canon 6D and an IDAS LPS V4 narrow band pass filter. Cumulative exposure is about 30 minutes at ISO 3200.

Although conditions last eve were again less than ideal, I tried imaging Jupiter with the AP155 and two 2x stacked Barlow or a final f/28 (about 3000 mm). This is my best result, stacking the best 100 out of 1000 frames with the ZWO ASI120MC. Hopefully no high haze and better seeing will help improve things.

I was shooting through a thin layer of clouds for these shots. It didn't clear up so I gave up around 8 PM.

I was shooting through a thin layer of clouds for these shots. It didn't clear up so I gave up around 8 PM. The transient moon shadow near the north limb was interesting. I do not think I have seen one this high up before.

Both of these Lunar photos were taken with the C-14 HD at f/11 and deep red filter and the ZWO ASI 120 MC camera in greyscale mode, stacked in Registax.

The first image is of the Ptolemeus Region and the second is of Deslandres.

A multi stack of 8 x 5 minute exposures with the C-14 HD at f/7, Canon 6D at ISO 6400 and IDAS LPS-V4 filter.

Finally got around to processing those solar images. Thanks for letting me strap the camera to the scope Dave [Frisk], it was a real treat!

The Lagoon nebula and NGC-6559

April 11, 2016

Here is one of the first images taken with my new (20 years old actually) Astro Physisc-155 mm EDF refractor. I obtained this fine telescope from my old friend Terry Dickinson, who thought it would get more use under our dark AZ skies. This mosaic of M-8 (the Lagoon nebula) and the adjacent NGC-6559 complex consists of 6 x 3 minute exposures at f/7 and ISO 3200 with a Canon 6D and IDAS LPS-v4 filter.

I'm always looking for "Lucky Seeing" but it wasn't here last night. Even though seeing was pretty steady transparency was poor. There was a high layer of atmospheric haze or thin clouds that denied capturing small detail.

Seeing last night was not as good as it was late last week but it was still fun to see Jupiter's moons in motion and the GRS in rotation.

The Rosette Nebula

April, 2016

This one is a closeup of the Rosette Nebula taken through narrowband filters. I used a hydrogen-alpha filter which is mapped to the orange/reddish tones, and Oxygen-III which is mapped to green and blue. This is about 15 hours of total exposure time taken over the last month, each exposure was 30 minutes long. Stacking and processing was done in Pixinsight.

Jupiter this last March

It never ceases to amaze me how a night of good seeing can produce bad images and yet another night of apparently good seeing might not. The images below were all shot last night in Movie Crop mode. The darn wind was gusting but in-between gust the seeing looked very good with Jupiter rock steady. That is more than I can say for my mount in the wind. True to shooting movie mode it can grab good frames from a bad set. These images were taken from video clips of 30 to 50 seconds at 60 fps. I stacked anywhere from 3 to 8% of the best frames in Registax and processed enhanced them in Photoshop.. They are not exceptionally good but some of the best I have been able to achieve in several years of trying.
