    After months and months of trying to improve guiding I have nailed it. The magic for me was putting an I.R. filter in the guide scope. This improved focusing beyond my dreams and hey presto 0.5 total error. Never got close to this figure ever.

    From the album: Deep Sky III

    NGC4725 is the brightest member of a galaxy group in the constellation Coma Berenices and is about 40million light years distant and 130,000 light years in diameter. The structure is somewhat unusual, consisting of just one spiral arm which is tightly wound around the core and can be followed for about 1.5 revolutions. The spiral arm consists of dust and gases including bright blue stars and pinkish Ha regions which indicate star forming regions. Towards the center, much older, yellow stars can be seen. The galaxy is classified as a Seyfert Galaxy, indicating that the center contains a supermassive black hole. The smaller galaxy on the right side is NGC4712 is within the galaxy group but is at the much greater distance of about 200million light years. The LRGB image below represents 12 hours integration time and was taken with my Esprit 150.

    From the album: Deep Sky III

    Located in the constellation Bootes, approximately 52000 light years from Earth, lies the globular cluster NGC 5466. It is designated as a class XII cluster, meaning that it has relatively non-concentrated stars towards the core compared to a class I cluster. This last fact starting me wondering if my scope would be able to resolve the "gaps" in the central core...... note also the various background galaxies. The LRGB image below was taken with my Esprit 150 and represents just over 9 hours integration time.

    From the album: Photos from Bury

    Date taken: 21 and 23 March 2020. Camera: Astro-Modified Canon 600D. Telescope: SW Esprit 100 with Field Flattener and Baader U-HCS filter. Mount: AZ-AQ6 mount Image: 60 light subs (3 minute with 15 sec interval) with master dark, Flat and bias each made from 80 subs. Comments: The Pinwheel Galaxy is a favourite goto object for me. There is good detail here but not quite beating my image obtained in Salisbury a few years ago. There is no substitute for a dark sky. The larger FoV of the Esprit 100 does capture the smaller galaxies in the background well though. I may try to add more subs to this one.

    Captured on the 26th of August 2020, Saturn with 5 moons (Tethys, Mimus, Enceladus, Rhea, Dione), 1 unconfirmed moon and a star up the top of the image. The blue dot towards the bottom right of the rings I'm not sure about, possibly Janus moon but Stellarium showed it nearer the ring. Seeing condition were average to good from Mandurah Western Australia. Captured in SharpCap 3.2, Stacked in AutoStakkert 3, wavelets in RegiStax 6 and edited in PaintDotNet. Saxon 8" Maksutov Cassegrain, ZWO ASI224MC, SkyWatcher EQ6 Pro.

    It's by no means a prize winning image, but it's my first one except photos of the moon. I even got andromeda in there and that makes my tummy tingle! Unprocessed of course.

    Moon at first Quarter May 2020. 127mm Meade Apo Refractor with Barlow f=2250mm. QHY5-11 colour camera. I really like this view with crater Posidonius in the foreground, craters Hercules and Atlas in the mid-ground and Endymion with terracing well displayed near the rim. Looking forward to trying out my new mono- version of this camera on the Moon.

    From the album: Deep Sky Imaging

    This is a center crop of Sh2-308, AKA The Dolphin Head Nebula in the constellation "Canis Major". This was imaged through Baader 7.5nm HAlpha & OIII narrowband filters using my full spectrum modded and cooled Canon 40D DSLR and the Bosma 80mm refractor at 500mm focal length. This photo consists of 46x1200s of HII, 35x1200s and 2x600s of OIII and 36x60s, 32x150s and 21x210s of RGB subs @ ISO1600 for a total exposure time of 30.5 hours. This object is very weak in HAlpha signal but very strong in OIII. The benefit of a color camera is that I captured two spectra lines in one exposure, I had OIII signal in the green channel while simultaneously captured HBeta in the blue channel in the stack. I assembled this image as HAlpha as Red, OIII as green and HBeta as blue. The weak HAlpha signal outlined some parts of the bubble (the front of the dolphins head) so even if the HAlpha was weak, it was not a waste of time as it added detail to the image.

    I did attempt this on a previous evening but it clouded up to much, that said a lot of cloud knocking about with this one as well and and half the frames were unsuable. I think it's not a bad attempt, even my flats seem to be working at the moment.

    The galaxy NGC4216 is in the Virgo Cluster about 55 million light years from Earth. It is shown in the center of the LRGB image below with two main companions NGC4206 (top) and NGC4222 (bottom). Also displayed are a few background galaxies. The inclination of NGC4216 is 89 degrees so, it is almost edge on, making the revelation of dust lanes difficult, so I was quite pleased that I managed to capture a few details. The image represents 12.5 hours integration time and was taken with my Esprit 150.

    Thor's Helmet Nebula, NGC 2359, located in the constellation Canis Major. This image total exposure time (of used subs) was 35 hours through HAlpha and OIII narrowband filters and was imaged through a 8" SCT at 2032mm focal length using a astro-modded and cooled DSLR. This image was a bit of a challenge with the Australian bushfires sending a lot of smoke into the atmosphere, causing me to throw out a lot of failed subs. 35 hours are the selected best subs I used on this image but have spent a lot more time in tracking this nebula from 30 November 2019 until 4 January 2020.

    From the album: Next Attempts at DSO's

    In December I uodated my copy of StarTools to v 1.6.386 beta and reprocessed some earlier images with this image showing particular improvement. The image was originally taken on the 28th February 2016 using a SkyWatcher Synscan Alt-Az mount, Canon 600D DSLR and StarTravel 102 refractor on M42 and M43 in Orion. The image below was stacked in DSS and processed in StarTools using 81 thirty second light exposures plus x50 dark frames and bias frames (I wasn't using flat frames at that time).

    Here's one you don't very often - the reflection nebula IC2087, which is embedded in the dark nebula Barnard 22. Since reflection nebula's are normally blue, I'm not too sure why this one is orange(ish)....I guess it must be the combination of the light from the bright blue star (out of frame), which is makes the background blue/purple, interacting with the dark brown/red of the dark nebula. IC2087 is also known as the little flame which seems appropriate since the stars above it appear like sparks from a small fire. For those with keen eyes, you'll also see a small red blotch above the fire, this isn't a processing artifact but a Herbig-Haro object which is a patch of nebulosity associated with newly born stars. So, you get quite a few interesting features in this image which was taken with my Esprit 150 and represents just under 10hours integration time.
