The Iris Nebula/NGC 7023/Caldwell 4 is a bright reflection nebula in Cepheus surrounded by substantial dust around 1300 light years from Earth. It is a circumpolar object which means that it is visible throughout the year and never sets, I imaged it from Austerfield late August/early September 2019 when it is highest in the sky.<br />

Then the colours were painstakingly altered to achieve different hues of blue to make the nebulosity appear to be water with the 'Fish' leaping out. The Fish is traditional Hubble Palette (SHO) mapped data that has been blended into the blue mapped data, so two images processed alongside each other and then blended together. </span></span><br />

IC1795 The Fish Head Nebula<br />
<br />
Part of the Heart Nebula Complex (IC 1805) which lies in Cassiopeia, around 6000 light years from Earth, it is a star forming region comprised of glowing gases and obscuring dust. This 'false colour' image utilises the Hubble palette where narrow-band emission data from Sulphur, Hydrogen and Oxygen gas is mapped to Red, Green and Blue channels respectively with a little bit of mixing to get good transitions of colour. The object Melotte 15 is also visible to the bottom left of the image which lies at the centre of the Heart Nebula. Captured using my own ZWO astro-cam attached to our astronomical society's telescope (Takahashi) and mount. The data was acquired over 5 different nights between October and December. Processed mostly in PixInsight with finishing touches in Photoshop and Lightroom. This is only my second narrow-band image and I am very pleased with how it turned out. It is just under 17 hours of data and it has probably taken me about the same amount of time to process the image.<br />

157 x 30s exposures, Sigma Art 14mm F4, ISO 100, Nikon D750. At least 6 hours of post processing work here.<br />
<br />
The mist looked nice but caused the lights to bloom - hence all of the post work to tame it. Also a dew heater would have helped keep condensation off the lens.<br />

Very tricky to edit because of cloud in a lot of the shots, I could have discarded those frames but that would mean much shorter trails. So some photoshop magic was involved to remove them, the reflection in the lake is not real, for two reasons, the aforementioned cloud and also there was a swan and other water foul floating around which made trails. So I copied the vista, flipped it and using one of my cleaner 'real' reflection frames as a reference I blurred (it was fairly still but a bit of a breeze which moved the water surface), stretched and darkened the reflection to match what it should look like.Jonathanhttp://www.blogger.com/profile/16240449765983742558noreply@blogger.com0tag:blogger.com,1999:blog-2604501175122605553.post-14791060941753506612020-07-26T10:13:00.002+01:002020-07-26T10:13:36.016+01:00Cusworth Hall Star Trails<div class="separator" style="clear: both; text-align: center;">

The Horsehead Nebula (Barnard 33) is a small dark nebula in the Orion constellation. The Flame Nebula (NGC 2024) is located to the lower left of the image and is an emission nebula. Reflection Nebula NGC 2023 can be seen below and left of the Horsehead and some other smaller nebulae IC435 (bottom) and IC432 (left).<br />
<br />
It is around 1500 light years from Earth and around 3.5 light years wide.<br />

The beginning of February 2019, I piggybacked my modded Nikon D5300 with the Nikon 180mm lens set to f3.5 onto the ODK whilst I imaged the Horsehead Nebula through the Tak with my ZWO camera - the ODK and the Tak are on the same mount, for those that don't know.<br />
<br />
61 x 5s ISO 800 - To get the stars in the trapezium<br />
<br />
17 x 120s ISO 800 - For everything else<br />
<br />

<br />
50 x 120s darks - probably overkill, but I was still imaging with the Tak/ZWO so just left the Nikon taking darks with the cap on<br />

Star trails over the bridge that allows the River Dun Navigation to cross over the River Don. When imaging star trails it can get a little boring because once you have set up the camera and got a composition and exposure that you are happy with you just leave it to do it's thing for ~1hr 20mins in this instance. So I tried some light painting to keep me occupied and here is the result.<br />
<br />
154 x 30s Sigma Art 14mm f1.8 @ ISO 500 and 7 x 30s @ ISO 800 stack for some bits of the foreground that were over(from blend)/underexposed. Nikon D750.<br />

<span style="font-family: Georgia, Times New Roman, serif; font-size: medium;">The lower object, surrounded by blue spiral arms, is spiral galaxy M81. Above this, marked by red gas and dust clouds, is irregular galaxy M82. These two galaxies are locked in gravitational combat, as they have been for the past billion years.</span><br />

The galaxy is approximately 30 million light years from Earth. The enclosed image was taken using a Skywatcher Esprit 100ED telescope with a ZWO ASI294 Pro one shot Cmos colour camera, consisting of 51 frames of 300 second each and 0 gain. The data was captured, calibrated and stacked in Astro Pixel by myself and Rachael Wood did a great job of processing the data in Photoshop.<br />
