And Olly's image is only two hours integration which demonstrates a significant advantage of large pixels... speed at gathering signal... just stick that 071 on your Borg and enjoy the results...after the snow stops of course!

Thanks Richard … quite amazing what an Esprit 100 can do! Dave

Thanks Adam.. so do I as they always seem to come out different! it seems to depend on how deep/strong the data is, the deeper it is the more I find I can push the colours Dave

Thank you Martin, much appreciated.. Dave

Nice one Goran.. I see a vaguely Star Destroyer shape in there..

Is it on all the subs? if so then its in the scope camera as Carole says.... if not then a branch or overhead cable as DaveS suggests...

Just over half the Heart Nebula in SHO. Imaged through my Esprit 150/SX-46 with piggybacked Esprit 100/ASI1600mm on a Mesu 200 from late September to last night. Half the Ha through the 150/SX-46 and the rest of the Ha plus Oiiii and Sii through the 100/ASI1600 This is a two panel mosaic totalling 26hours Ha, 12hrs Oiii and 10hrs Sii. Processed in Pixinsight and Photoshop with use made of the StarNet++ module in Pixinsight to take the stars out of the Oiii and Sii which I then replaced with the much tighter stars from the Ha. The Heart Nebula, IC 1805, Sharpless 2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896 (The Fish Head Nebula), because it was the first part of the nebula to be discovered. The nebula's intense output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. Planetary Webo 1 can be seen in the lower left corner. Thanks for looking Dave

If you want wide field I'd just try the Borg with the ASI071 and see what you get Alan before spending money, it'll have essentially the same FOV and "pp (slightly lower in fact) as a Tak106 and kaf11000 camera combination.. And yes I too have a collection of Skywatcher finders, diagonals and eyepieces Dave

Hi Alan.. I believe you’ll need a flattener with that scope, but I shouldn’t worry about that pixel scale being too much, there’s plenty of APODs out there at 3”/pp.. ie Tak106/kaf11000 images, just don’t zoom in too much.. if you want 500-550 mm then you won’t go wrong with an Esprit100, plenty of excellent Esprit100/ASI071 images around.. if you wanted to go shorter still maybe the GT71 at 350mm or so would work well with your ASI183. Also be aware that WO have 70 and 90mm versions of the RedCat in the pipeline.. so just the usual downsides.. like me, you’ll always want something else as well! Dave

Hi Brian, it's a lovely target but tricky as it's so dim.. Olly put up his image on here a few weeks ago, 28 hrs in total, its worth a look.. probably take 3-4 times that from where I am to get a similar result... anyway good luck with it Dave

Looks ok to me Brian, I tried this on Friday night and discovered that it's pretty dim, my 300s subs looked just like yours Dave

Have you got the backlash set high enough, not sure how to do that in APT

Fabulous, congratulations to the winners Dave

The Esprit 150 is no slouch either! Dave

Look forward to it Steve

Nice Steve, lovely star colour and a glimpse of the Heart .. do you feel a mosaic coming on? DC Heart and Soul Dave

Oh that's lovely Richard.. well done and well done to Olly! Dave

Mark Nice Bubble and M52.. Whilst better your last image shows some signs of amp glow (the two slight glows on the right hand edge) which with the asi1600 should calibrate out if your darks match your lights exactly in exposure length temperature gain and offset.. I’d check two things firstly that they do and secondly that you have “optimise” unchecked in Pi’s image calibration process.. hth Dave

I think you should be hugely encouraged by what you have achieved, getting all that working in one evening is no mean feat in itself, your stars are nice and round so your guiding is working well and for only one hour of LRGB on a low surface brightness object (mag 22.8 apparently) in Bortle 8 it's good. Dave

Do you start SGP from scratch every time or do you overwrite an existing sequence? When I do the later the preview screen from the previous run pops up and continues to do so no matter what I do to get rid of it. You can stop the preview screen showing at all when you create a sequence by unchecking "Associate working image with sequence".. HTH Dave

Thanks.. this was my go to target when I started out.. spent many many nights trying to get a decent image through my LX200 with various DSLRs.. then on the advice of various well known SGLers brought a refractor (or two) ..

Thanks Richard and Goran, might be my settings of course with Pixinsight.. the recent update did mess me about though, calibration went wrong as the darks got turned upside down for some reason..

After what seems like weeks of poor weather the clouds cleared long enough on Monday night to capture 3 hrs of luminance with my Esprit 150 SX-46 and an hour each of RGB with my piggybacked Esprit 100 ASI1600. I processed the image with a combination of APP (currently using the trial version) and Photoshop, interestingly from the same data APP produced an RGB combination with stronger colour and all integrations had higher SNR and lower FWHM than Pi.. I added in some Ha data in Photoshop that I'd taken this time last year with the Esprit 150 ASI1600 combo.. “Spiral galaxy M33 is located in the triangle-shaped constellation Triangulum, earning it the nickname the Triangulum galaxy. About half the size of our Milky Way galaxy, M33 is the third-largest member of our Local Group of galaxies following the Andromeda galaxy (M31) and the Milky Way. Clearly visible in the image is NGC 604, an enormous star-forming nebula. Spanning almost 1,500 light-years, NGC 604 is nearly 100 times larger than the Orion Nebula in our own galaxy and contains more than 200 hot massive stars. M33 has a relatively bright apparent magnitude of 5.7, making it one of the most distant objects that keen-eyed observers can view with the unaided eye (under exceptionally clear and dark skies). Although a telescope will start to reveal some of M33’s spiral features, the diffuse galaxy is actually easiest to examine with low magnification and a wide field of view, such as through binoculars. It is best observed in October. Although others may have viewed the galaxy earlier, Charles Messier was the first to catalogue M33 after observing it in August 1764. In the 1920s, astronomer Edwin Hubble studied dozens of variable stars in M33, which helped him to estimate the object’s distance and prove that M33 is not a nebula within our own galaxy, as previously suspected, but actually a separate galaxy outside our own.” Source NASA Thanks for looking Dave

Thanks Rodd.. needs more and better data really (especially RGB).. to sort those fuzzy stars out. Owing to persisitent cloud I've only managed an hour per channel RGB in each of the four panes so far and the reds were taken low down hence the issue I guess.. Dave

Thanks Vlaiv… with the Ha I blended Starless and Starry at 50:50 but didn't with the Oiii.. so maybe that's why.. Dave
