When including Ha in an image, it is a good idea to do longer RGB exposures as the colour is less strong when narrowband is included.

While I do appreciate the suggestion, I think you've misunderstood my intention (and perhaps my processing technique); what I had done was, in fact, the exact opposite of this, taking considerably more data of the area's Hydrogen Lyman-alpha spectrum to highlight the detail of the structure of the nebulous regions. (This was also to dull Alnitak's normally-overpowering glare.)

AR 11967 & 11968: The Sun, 2/feb/2014
What can you expect from a modest solar telescope like the PST?

This picture is a mosaic composed of 4 images for the inside part of the Sun and another 4 images for the periferical part (which require more expoure time). It's captured using an standard H-alpha PST 40mm telescope and a DMK618 camera. Each image is composed 2000 frames video from whom only the 800 best frames were used. Mount was a manually actuated, very lightweight and simple EQ1 equational mount.

Procesing software: Registax 6 (freeware), PixInsigh Core and Gimp (GNU).

Please, visit my web page at www.astronomica.es for fully detailed image information.

These detailed pictures of the active regions were captured using the same equipment, adding a x2 balow lens. 2000 frames each from whom the 800 best frames were used:

Orion and Canis Major against the light pollution of the northern Italy plain.
This image was taken on Mt. Mottarone (1400m over the Major Lake, a big lake NW of Milan) on the end of Jan 2014.
It is a comoposition of 3 shoots: 2 for Orion and Canis Major, one for the panorama.
I used a fluo filter to have bright and coloured stars and then I removed it to have the correct detail on the landscape.

2014 seems to be an explosive year since already we have two supernovae explosions happening in the very familiar galaxies M82 and now M99! Here is an image that shows the second explosion:

Sh2-188 - An old-fashion B/W picture of a peculiar planetary nebula in Cassiopea

This is a picture of the peculiar planetary nebula Sh2-188 in Cassiopea taken through a 6nm narrow band Hydrogen Alpha filter. The very long exposure (more than 20 hours) allowed to detect the faintest part of the nebula, the extension of which is very noticeable if compared to the dimension of the brightest part.

Centaurus A Extreme Deep Field - 120 Hours - New Version Feb 2014

The Deepest View Ever Obtained of Centaurus A (NGC 5128)
New Improved Version, Feb 2014
Having spent much of the past year exploring new image processing tools and refining skills in that area I felt it was time to do a repro of my 120 hour Centaurus A image. I'm still happy with the original version, but... one cannot sit on such a pile of data without making the most of it.
I think this new version is a big improvement over the original - it's even hard to see it is the same data.
This time I was able to bring out the concentric shells much more and at the same time give the image a more subtle natural look.
I started from scratch and did a complete re-registration and combine of the data again, followed by about two weeks of nightly tinkering in PixInsight. The new version also has slightly higher resolution than the old one, despite it looking more relaxed and less 'processed'.

About the Image
This image is the realisation of a long time dream of mine: Taking a deep sky image with more than 100 hours of exposure.
I set out on this mission in early 2013 and after having gathered 120 hours of data on 43 different nights in Feb-May 2013 I present what I believe is the deepest view ever obtained of Centaurus A. This is likely also the deepest image ever taken with amateur equipment, showing stars as faint as magnitude 25.45.
I spent around 40 hours and analysing processing the data, with the goal of presenting this majestic Southern galaxy as it has never been seen before - with all the main features showing in one single image, in order to truly get a grasp of what this intriguing object is all about.

Visible are some unique features, some of which have never been imaged before by amateurs:

A set of enormous reddish filaments associated with the relativistic jets.
The complete shell structure of the extended halo, showing both the faint outer shells and brighter inner ones.
709 of the catalogued globular clusters orbiting the galaxy.
Integrated Flux Nebulae permeating the entire field of view around the galaxy.

Image details
Date: Taken over 43 nights in Feb-May 2013

Hello:

On october the 10th, a non very usual astronomical event took place on planet Jupiter. The shadows of Callisto, Europa an Io, were cast on the gas giant surface. It´s not very usual to be able to observe a triple shadow on Jupiter, so this was a scpecial event for me.

In this mosaic, I have included the position of the shadows, between 03:33 and 05:57 U.T.

I have included a new image, because the mosaic I published before, had one that had been repeated (by mistake), so now has been corrected.

Greetings

Recently there was a supernova in M82, the Cigar galaxy. Last 2 nights I could image this supernova together with the ‘sister’ galaxy of M82, which is M81, aka Bode’s galaxy.

In total I got 17.3 hours of imagery for this one. I even detect some IFN (Integrated Flux Nebula) in the image from my very light polluted (Bortle scale 7-8) location.
