  1. Yeah you are fighting an uphill battle especially without a filter to help boost the contrast. See my efforts below. Very tricky to be honest. StarNet output Stars in one way Stars back in another way.
  2. I used to use PHD with astroberry for this exact reason, my T7C (ASI120 clone) never seemed to work with EKOS. I can't remember what I needed to change exactly to get the guidecam to work in EKOS I will have a look later, one thing I do know if I connect it to a USB 3 port (the blue ones for those of a less techie disposition) EKOS wont take an image even though it connects, it has to be on a USB 2 port (the black ones).
  3. I dunno, I think there are a few of us who could make a good argument for the AZ GTI I think when it comes to the AZGTI vs the SAGTI I think its worth remembering that the SAGTI just works for this out of the box, alot of people will be put off by the thought of having to update the firmware, mess around getting a wedge etc etc. I can see the appeal of the SAGTI and I will probably add one to my collection when the initial rush calms down/a good second hand deal comes up. I also have an EQ6 and other heavier scopes, when you want that higher resolution or more focal length etc then they really do come into their own. I bought my GTI primarily for the ability to take it with me when we go on holiday or star parties I think a lot of people fall into this bracket.
  4. I don't miss the heat of being out there, like walking into a fan oven when leaving the hotel/compound
  5. Mine will drop to -10 no problem at all in these temps (Altair 533Protech) Having done some reading it seems pretty pointless cooling most sensors past -10c
  6. Yeah take your time, a few extra minutes focussing can save you much pain. I would definitely drop the sub length down from 5 minutes. I would suggest playing with anything between 1 and 3 minutes. Not sure I would raise the gain past what is considered unity gain for that camera, you'll just bring in more noise to remove at this stage. Especially as you aren't dithering yet.
  7. No worries. The initial learning curve can be a bit steep but once you have the basics down you are good to go. Have a watch of some youtube guides to get your flats sorted properly for when you do need them, fortunately your field is quite flat and your optics clean so I was able to run without them for you. In terms of your darks, no idea what would cause it but here is a comparison for you, top one is Dark 1, Bottom is Dark 8. You can clearly see the light leak top right. Even in Dark 8 you can see it there unless that is amp glow maybe. Also you need to make sure darks are shot at or as close to as you can get the same temperature as your lights. Light leak usually comes from focusers so make sure everything is covered and that you are in a darkened space when doing them, good news is they can be reused once you have a series of master darks at various temps etc. What scope are you using? Do you have a bahtinov mask? This will allow you to get your focus just right and then you can lock the focuser off to stop it moving during imaging.
  8. You're welcome. I've uploaded the stacks etc for you and included a quick readme to cover which file is which plus the original pngs of the output I put on here for you. https://1drv.ms/u/s!Aqjp7A3ixBHurck112KKBTFAJyke1w?e=CjHpg1
  9. @Bignose13 A couple of things, first things first, you appear to either two sets of data there or you have drifted off target in your lights. Also you have quite a few that had to be excluded because the stars drifted in frame, also I would drop down from 5 minute subs to 3 minutes tops (you have massive star bloat) lastly your focus is ever so slightly out. Second, your darks have light leak bar darks 7,8,9,10 so I only used those. Your flats weren't right either, don't bother bias but use dark flats which are frames the same length and gain as flats but with the scope etc covered. That said I was able to get this out of it for you using 27 of your lights the four dark frames (flats in this instance weren't needed luckily). You can see there is a bit of cropping needed still. I ran a very quick process of them there is a little more you could pull out and play with the colours etc. I will upload the stacks etc for you to have a look at. With stars: Without: Hope you like them!
  10. Google Drive? Drop Box? Onedrive? Or I can set one up where you can upload the files to if you like?
  11. Walking noise aside, its possible you have a better image there than is being shown. If you are willing to make the subs and calibration frames available I would like to have a run at it to see if I can get anything better out of it for you.
  12. Thanks I am very pleased with how it came out especially given the limitations of the setup. I am currently stripping out the HA/Oii from it so I can do a "Hubble pallet" version of it too. Good luck with your run I hope it turns out well
  13. Added to my Soul Nebula last night and I think I am ready to call this one done. SH2199 - The Soul Nebula 91 x 3 mins, Altair Astro 60 EDF with 0.8 Reducer, Altair Astro Triband Filter, Altair Astro 533mc Protech
  14. Thanks I am imaging from my back garden, we moved back in April and these were my first shots from the new house, have moved from a B8 to a low B4 , the difference is staggering!
  15. Thanks for the kinds words! RE the star reduction I completely agree, I am still learning that bit, my soul neb was my first attempt at stripping the stars, stretching the nebula and adding them back in, I am still learning the processing side of things (it's my biggest weak area) and I am not sure I did it all in the right order. Tonight I will be grabbing more Soul data, plan for process tomorrow is, stack and remove LP in APP, save Tiff without stretch, remove stars, stretch starless in APP and tweak in PS. Then add stars back in and see how I go. If anyone wants to offer an advance/advice on this feel free
  16. Have managed a couple of evenings with the GTi now. Guiding is a bit off but I will tweak that where I can. Two pics, Andromeda 120 x 1min (no filters) and Soul Neb 45 x 3min (Altair Triband). Both on a Altair Astro 60EDF with a 0.8 reducer and an Altair Astro 533MC Protech
  17. Yeah as someone else who spent a large amount of time shooting from a B7/8 the step up from an unmodded-DSLR to a OSC astrocam with a good filter the difference was... well.... night and day. I keep more than one filter depending on what I am shooting. I have an IDAS LPS D2 and also an Altair Triband.
  18. I haven't run my 130 much lately owing to the recent purchase of a 72ED. However here is the last image it shot, very happy with this. Target: IC443 - The Jellyfish Nebula Dates: 6th January Integration: 5hrs 45mins Lights: 115x180s @100 gain -10.00c Darks: 30 Flats: 30 Dark Flats: 30 Bortle: 7-8 Equipment: Altair Hypercam 533C, IDAS LPS D2 2" Filter, Skywatcher 130PDS, Skywatcher EQ5 Pro, Astro Essentials 50mm Guide Scope, T7C Guide Cam, Raspberry Pi4 and Astroberry Processed with Astro Pixel Processor and Photoshop
  19. Getting to grips with my new Astrocam The Horse Head and Flame in Orion. Dates: 5th November Integration: 4hrs 45mins Lights: 95x180s @100 gain -10.00c Darks: 60 Flats: 30 Dark Flats: 30 Bortle: 7-8 Equipment: Altair Hypercam 533C, IDAS LPS D2 2" Filter, Skywatcher 130PDS, Skywatcher EQ5 Pro, Astro Essentials 50mm Guide Scope, T7C Guide Cam, Raspberry Pi4 and Astroberry Processed with SiriL and Photoshop
  20. Seen similar go for about this I would says its about right. Also I would be interested in taking it off your hands, have sent you a PM
  21. My latest one, had the data for a short while but hadn't had a chance to process it until now. My love affair with the 130PDS continues. This isnt my greatest image but I am still really pleased with it. Unmodified Canon 6D, Optolong CLS filter, 40 x 180s lights @1600 ISO 20 x darks, flats and bias, SW 130PDS EQ5 Pro T7C guide cam SVBony SV165 guide scope DSS no drizzle and a solo process in Gimp.
  22. Loving this little light bucket more and more! I really do need to learn how to process though. I also desperately need a coma corrector. NGC6888 Crescent Nebula. Unmodified Canon 6D, Optolong CLS filter, 121 x 180s lights @1600 ISO 20 x darks, flats and bias, SW 130PDS EQ5 Pro T7C guide cam SVBony SV165 guide scope DSS x2 drizzle, Gimp and PS (I had a lot of assistance with the processing a big thanks to jenastro from the Astrbiscuit discord) Also a quick shout of to @Spaced Outwho sold me his PDS .
  23. Finally feel worthy enough posting my first proper nebula image shot from a Bortle 8. NGC7000 North America Nebula. Unmodified Canon 6D, Optolong CLS filter, 33 x 180s lights, 20 x darks, flats and bias, SW 130PDS EQ5 Pro T7C guide cam SVBony SV165 guide scope DSS, Gimp and PS (I had a little assistance with the processing from AstroN3RD on the Astrobiscuit discord)
