  8. This was a short capture done while waiting for the Soul Nebula to become accessible. Around 30 x 60s and 20 x 120s subs using Redcat, l-eNhance tri-band filter and ASI294mc pro on Star adventurer. I wanted to have something to play around with using something like the SHO pallet, so I processed separate channels in Astro Pixel Processor:- A false channel (Ha-0III Mono) acting as SII for Red Ha for Green Oxygen III for Blue Merged the Channels in Photoshop then adjusted slighly using Channel Mixer adjustment layer before stripping out the stars and processing the starless image. Processing was mainly iterative Selective Colour adjustments and Camera Raw Filter Processed the separate Star Layer before merging and final cleanup.

  9. The Crescent Nebula in SHO. It was harder than I was expecting, to bring out the detail in the blue, and the stars are looking funky too.

  10. 'tis the season... This is a reprocess of some data I captured earlier. I binned the linear stacks after they came out of DSS and before processing. Linear histo stretch, then Trichromy. DDP then edge crop, Colour Balance (Pulled the green down a bit) and Gradient Removal. A light Unsharp Mask followed by a Histo Stretch with curves with a final saturation boost. C&C welcome, as always.

  12. LDN1251 in Cepheus, Imaged from Spain with the Tak Epsilon 180ed. I've just fitted a new ZWO ASI2600MC to it and this is the first image. 96x 300s exposures, 8hrs total. I really like this chip!. Plagued with satellite trails I was still able to use every exposure. The shear number of subs gave a good rejection in the stack with no signs of satellites in the final image even after such an aggressive process. Processed with Pixinsight and Photoshop Thanks for looking Peter

  14. Hi all, i know this time of year is not great for astro as there isn't much dark sky to image in. This is just over four hours image time in 300s..240s and 90s subs of M57 the ring nebula in Lyra, taken this last three weeks. I had to bin around half of the subs taken.

  15. M31 the Andromeda Galaxy bathed in ionised Hydrogen. Imaged from Spain with the FSQ 106ed at f3.6 and the stunning ZWO ASI-6200 full frame Cmos camera. Exposure times were 140 x 240s frames in H-a with LRGB 100 x 180s in each channel a total of nearly 31hours. The faint H-alpha in the background was very difficult for me to pull out probably making this my most challenging process to date. Thanks for looking Peter Shah here is a revised version with some work done on the the background Luminance layer that was showing some additional structure

  16. Managed to grab just short of a two-hour window to try out the L-eNhance filter with the Redcat. The Veil complex seemed like the best bet given the window of time before the balcony roof would intrude. 36 x 180 secs with Darks and Bad Pixel Map (no flats or dark flats yet for this combo) WO Redcat 51 with Optolong L-eNhance filter using ASI294mc pro on a StarAdventurer tracker Processed in Astro Pixel Processor, starnet++ and Photoshop (plus AstroFlat Pro add-on)

  17. Hi all, I had my first go at Solar using a Ha scope the other day. Exciting stuff and lots to learn (such as adjusting the tilt adapter to remove the Newton’s Rings). Also below are a few images using a normal solar filter on my Nexstar 4SE to capture the gigantic active region.

  18. I have a long time project here of NGC7822 in Cepheus experimenting with the mosaic capabilities of Astroberry/EKOS/INDI/Kstars. There were a few human errors along the way like setting the incorrect gain on the camera for instance. Lots of those frames have been thrown away. This is the result and it does show up the dusty stuff surrounding the nebula. I chose to go for a more natural coloured image rather than the rather garish false blues/yellows that you sometimes see of this nebula when processed in SHO. Stitching of the mosaic panels using Pixinsight was easy and I used the Imagesolver script to plate solve each of the 4 resulting panes to add the resulting co-ordinates to the FITS header of each pane. Then I used the MosaicByCoordinates script to create 4 registered frames ready for combination with the GradientMergeMosaic script. For the latter the settings I used were these The above created a seamless transition between all 4 frames. The one caveat you have to bear in mind is the original mosaic frames need Dynamic Background extraction or the older Auto Background extraction to remove any uneven field illumination between frames. I was lucky when I captured the images in that the moon wasn't up at all apart from 14th April onwards where it was low and hidden by surrounding houses. Telescope - William Optics ZS103 with x0.8 reducer/flattener Mount - Skywatcher HEQ5-Pro Rowan Camera - ZWO ASI183MM Mono Capture device - Raspberry PI4 running Astroberry/INDI Server Capture location - West Manchester Bortle 7/8 with mucho light pollution Capture dates - April 2nd to 16th 2021 over a few nights when the clouds had parted Filters - Ha, SII and OIII Processed with PixInsight as SHO 75 x Ha at 360 seconds Gain 111 Offset 8 112 x OIII at 360 seconds Gain 111 Offset 8 72 x SII at 360 seconds Gain 111 Offset 8 The total of nearly 26 hours for all three filters of course are spread over 4 panes with a roughly 15% overlap in the centre region. I like doing mosaics but will probably limit myself to the easier 2 frame mosaics unless a target appears that I fancy doing another 4 panes or even more....

  19. This is NGC7023 aka the Iris Nebula, a bright reflection nebula in Cepheus. NGC7023 refers to the open cluster inside the nebula. The entire is also known as Caldwell 4. Imaging is a total of 3 hours RGB, with a small amount of Luminance added, captured from Bortle 2 Kerry Dark Sky Reserve on 20th July but unfortunately with no astro darkness. Imaging: Esprit 80, ASI160MM Pro @ -20C, gain 139, Baader RGB filters. Guiding: Starwave 50mm, ASI290mm Mini, HEQ5 Pro belt mod. Capture control: NINA, PHD2, SharpCap PA. Processing: APP, Gimp, Noise Ninja.

  21. Hi all, here's my first effort with the wizard nebula. This 4.5 hours of 3 min subs with a dslr (stock) and a optolong l enhance filter. I downloaded the trial version of pixinsight to see if it was better at extracting Ha and O111 from a dual narrowband filter and have to say I'm impressed at what this software can do. I'm still serving my apprenticeship with my old trusty dslr so noise is always a challenge so will upgrade to a dedicated camera at some point. Overall though as a first attempt both with the target and software I'm fairly pleased. Cheers Paul

  24. Spent a little time on a second version. This time I didn't do a linear fit just background neutralisation as I found LF created too much noise. I used NBRGBCombination and this time tried out Masked Stretch. The core is far better defined in M81 and there didn't seem to be any loss of finer detail. Also managed to smooth the background out a lot.

  25. Hi all, here's my version of the Tulip. Imaged between the 16th and 22nd of July in a record 6 night stint. This is a combination of 33 x 10 mins Ha 17 x 10 mins Oiii 28 x 10 mins Sii I used a straight SHO combination then added Ha again as luminance. Lost a fair number of subs as seeing wasn't so great at times, I was aiming for 40 of each. Fully integrated and processed in Pixinsight

  31. The weather has been lovely hasn't it. But despite the high humidity of recent days. I was able to get some reasonable images of our daytime Star in the Ha wavelength. I have a Daystar Quark Chromosphere which is coupled to a Sky Watcher-Star Travel 102 F5 Achromat. This is an ideal telescope for imaging or observing the Sun in the Hydrogen Alpha wavelength, despite the F5 focal ratio. It is also a very good Achromatic telescope. When I did use it visually. I wasn't able to detect any colour fringing surrounding bright stars or buildings. Using the Quark Chromosphere with my telescope. I am able to get an increased focal ratio from F5 to, F21.5 with an increase in focal length from 500mm to. 2,105mm. I am also using a Altair GPCAM3 290M and a UV/IR filter. That filter is attached to the front of the Quark. The camera with its small pixels, 2.4x2.4um allows me to get a good high resolution of the Sun, or the Moon. It is an excellent camera. Typically. I can get 125fps with SharpCap Pro 4.0 and I normally capture between 500 to 2000 avi, depending on the seeing conditions. I also like to start early, when the seeing usually very good. So with out further ado. Here are my recent images of our daytime Star

  37. Initial processing of last nights capture shows the Cygnus wall well. I changed the framing from the previous night and rotated the camera 90 degrees to the left. 42 x 6 minute subs with the ASI183MM attached to the WOZS103. Just darks at the moment as I need to get some fresh flats. The 183's inherent amp glow calibrated completely out. I shall carry on tonight with OIII filter.

  39. This image was first light in January for the Altair 26C I bought in December. I was blown away at the stack just out of calibration and integration using only flats to calibrate. I was through 2 or 3 rounds of processing when my laptop HD failed costing me everything I had captured with a dedicated camera up to that point. Lesson learned and I have multiple backups now lol. I recently started playing around with non-linear star reduction and wanted to share this "final" version of own of my favorite images taken so far.

I don't normally give too much in the way of likes and comments to images done robotically, but in your case I know you probably set it all up and maintained it yourself, so I will treat it the same as BackYard imaging. Lovely image Peter, glad you found something to do during your quarantine after visiting Spain to do this maintenance work. Only 1 hour in Ha????? Carole

  44. Heya, It's been a nasty few weeks here in Florida, the storming just hasn't let up until this afternoon in a solid 16 days straight of clouds and rain. I missed that last spot and missed out on some really great proms the past few days. Thankfully there's a new active region with a very interesting spot! AR2835 is pretty interesting because it doesn't have massive activity going on despite how it "looks" to us, and it's because it's magnetic polarity is very split and far apart, so there's no reconnections occurring resulting in flares (at least so far!). Lots of neat stuff going on in the inner spot with light bridges forming. These spots sprang into life over just around 2 days or so and are still going, so it will be nice to see them stick around for a disc face transit hopefully! I'll probably get rained out the next few days just because! B&W: Colored: Seeing Conditions: Not my typical, I had nothing for weeks. This evening was my first chance to even look at the sky nice the beginning of the month. So after 4pm Eastern Time, I had not expected good seeing, but it was good enough to attempt things with good transparency between large cumulus clouds dragging nice air flow patterns behind them. Lucky imaging prevailed despite my averages to allow high resolution in 0.8 arc-second peaks for the continuum and CaK imaging. Equipment: Celestron Omni XLT 120mm F8.3 refractor (air space gap for diffraction limited in near UV); masked to 100mm F10 + Lunt CaK Module + IMX253 camera (CaK Disc) + Lunt CaK Module + 1.62x barlow (F16) + IMX290 camera (CaK High Res) + Baader 2" Cool-Ceramic Wedge + ND3.0 + Continuum 540nm + IMX253 camera (Photosphere Disc) Celestron C6R 150mm F8 refractor + Baader 2" Cool-Ceramic Wedge + ND 3.0 + Continuum 540nm + 1.62x barlow (F13) + IMX290 camera (Photosphere High Res) + 120mm mask (F10) + Baader Red CCD-IR Block Filter (sub-aperture internal D-ERF) + PST Etalon + 10mm BF + IMX290 camera (HA Moderate Res) A look at my skies the past 2+ weeks, Sunny Florida!
