Sh2-202 (Sharpless 202) Samyang 135mm
This image shows Sh2-202 glowing to the left of centre with the top of the Soul Nebula at the bottom. Several other Sharpless Catalogue objects are also visible together with a few objects from the VdB catalogue.
Image Technical Data
This image was captured from my back yard with my widefield rig consisting of my Samyang 135mm lens with Moravian Instruments G2-8300 CCD camera and Astrodon RGBHa filters. I used my NEQ6 mount. The data was acquired when the object was overhead from Nottingham UK on 29 November 2019. All data acquired in one imaging run and all exposures binned 1x1 and 300seconds:
Ha(3nm) 180 mins, Red>50mins, Blue>45mins,Green>45mins
I hope you like it!
The North American Nebula with Samyang 135mm
Above is 120 minutes worth of Hydrogen Alpha data captured in five minute exposures with an Astrodon Ha 3nm filter and a Samyang 135mm camera lens on a Moravian Instruments G2-8300 CCD camera.
I then captured one hour in each of the Astrodon R,G and B filters with the same rig as detailed for the Ha image, again in five minute exposures. However, use of the superb Astrodon E series RGB filters produce a nice image and the colours are brought out quite nicely although it lacks a bit of punch and vibrancy.
The bright star to the right is Deneb.
In Photoshop I broke out the red channel and then blended it as a 50:50 mix with the Ha image (at the top of this page) before recombining back into RGB. I also saved a copy of this HaR constituent and then used that as a luminance layer to really make the image pop. I then used a series of high pass filters to reveal finer structures in the image.
M45 in a Widefield
An image of the Pleiades taken with a Samyang 135mm lens and Astrodon RGB filters.
Field of view is approximately 6x4 degrees.
Taken 18 November 2019 and 10 x 180s exposures in each filter.
Virgo Cluster in Wide Field Setting
This is the Virgo Cluster of galaxies presented in a wide field setting. The cluster is a popular area for amateur astronomers and professionals alike and contains some very important galaxies, the most important of which is M87, the supergiant elliptical galaxy and one of the largest galaxies in the local universe.
You can see Markarian's Chain demonstrated at an unfamiliar angle in this picture.
The picture is comprised from data captured during late March 2020 and I used my Samyang 135mm DSLR lens connected to G2-8300 cooled CCD camera from Moravian Instruments and Astrodon RGB filters. The picture is comprised of 70 minutes (of five minute exposures binned 1x1) in each of the red, green and blue filters to give a total integration time of three hours and thirty minutes. The data was developed with PixInsight and Photoshop.
The Leo Triplet in a Widefield
The Leo Triplet is a popular trio of galaxies in the constellation of Leo, popular with amateur and professional astronomers alike. They are visible in the late winter and spring in the Northern Hemisphere. Consisting of M65, M66 and NGC 3628, the galaxies are about 35 million light years away. NGC 3628 was never given the distinction of as Messier number for some reason, even though it is as bright as the other two members.
The image was taken with my Samyang 135mm DLSR lens coupled with Moravian G2-8300 cooled CCD camera with Astrodon RGB filters. It consists of seventy minutes (5 minute exposures binned 1x1) in each of the red, green and blue filters to give a total integration time of three hours and thirty minutes.
The triplet was about 45 degrees above the horizon when the exposures were captured. IT was then processed with Pixinsight and Photoshop.
