  1. Another short break in the clouds allowed me to get some time on a new target for me. This is only 90 minutes of 180s with the ASI2600mc but I think that for that integration time its not too bad. I was astonished at how much of the blue part of the nebula was standing out considering that this was Monday of this week and so moon was still 90%. I only wish only I could get some real time on something to do this camera it justice but I am becoming quite impressed with it. 30 X 180s, SW 80ED, NEQ6, ASI2600mc, 2" L-eNhance C&C welcome
  2. I continue to be plagued by poor skies so am struggling to give the new ASI2600 a decent try out. But Sunday gave me a few hours so I thought I'd try the Rosette. So this is 67 X 180s (3.25 hrs) with the Skywatcher 80 ED, NEQ6, ASI2600mc, L-eNhance. Moon was 97% and about 90 degrees away so could have been worse. There is a bit of coma out at the corners which I think is backspacing so I have added a 0.5mm spacer into the train which I hope will make the difference. Stacked in APP, mostly processed in PI with finishing touches in PS C&C very welcome.
  3. That's a really nice image. The filter did a great job. Interesting that you see it as an anatomical heart diagram as I do. I think many people turn it on its side and see a love heart. But for me it is remarkable how close it is to my heart diagram from 4th year at school. In fact it's probably more correct than mine was
  4. I have found M51 to be an unexpectedly difficult target and honestly I think you are going to struggle on it with a full moon. I'm in Bortle 4 also and without my l-enhance filter I'd not try anything other than clusters. But to answer your question, with that much moon and that scope at iso800 you'll be looking at the lower end of your suggested exposure (120s or even 60) youll know quickly enough once you get your first image and check the histogram. Good luck and be sure to let us know how you get on.
  5. Thats a cracker. Love the colours
  6. I agree with whats already said, not much wrong with that. What are you using for processing because I do think you have more in the data than you are showing.
  7. So after 7 weeks of unremitting cloud I finally got the new camera outside. for all of 90 minutes before Orion started to get too low and clouds started to build again. But at least I got an image. This is 15 each of 180s, 120s and 60s. I did that partly to get a handle on how the camera performs and of course to try to get some detail in the core. SW 80ED, NEQ6, ASI2600mc pro, L-eNhance It is stacked in APP using the Ha-Oiii colour algorithm then a very quick hash through in Pixinsight. Overall I'm pretty happy with it - a bit grainy when you zoom in hard and I'm not sure
  8. Great first go with this technique . Well done indeed. I'm looking on my phone and for me the colours look really good, red is very slightly pink but not enough to worry about and contrast is spot on. I'll look on the computer later but I've had that same problem in the past sometimes with wide variation between monitor and phone / tablet. I think I read somewhere that its an intrinsic difference in the way the screens work. I have adjusted my monitor to try to get them close as I think in this day and age our images are seen more on mobile screens than computers. Looking forward t
  9. That's a nice image and I'm sure you could get more blue in it. Have a look at this tutorial. I have used that technique with L-enhance data to produce some reasonable results like https://astrob.in/gc842f/B And https://astrob.in/ye7dzb/0 Good luck.
  10. My first attempt with this challenge. Processed In PixInsight with some finishing touches in PS. Done as HSO as I'm not really comfortable with the SHO pallet yet. I wanted to emphasise the ghost and his tail and minimise y-Cas. I did this with much masking and stretching in PI Lovely data like this makes processing so much easier and I really did not have to do that much to it In Pixinsight; Decon and a gentle denoise (MLT) on the Ha Stretched all three gently using HT - further stretches with Star masks and range masks to focus on the nebula and keep y Cas in check.
  11. Yes they will but you need to make sure the m42 to eos adapter states "infinity focus" as some of the thicker ones will not.
  12. I have an old Pentacon 135mm which I used on my canon 1100d and sky adventurer a few times. I was just starting out in AP but was delighted with the results. CA was not noticeable and no obvious coma except out in the far corners. Here are 2 images with it. They are not very good but like I say, I was just starting out https://www.astrobin.com/q7jg0g/?image_list_page=2&nc=&nce= https://www.astrobin.com/4c5g0f/?image_list_page=2&nc=&nce= I also have a Takumar 200mm which I think is fantastic so i think you could do worse than try a Takumar. https://www.
  13. As I said in your other thread about this, if you can't reduce brightness of the panel put some layers of t shirt or paper between until you get a decent exposure time.
  14. Look in the APT users manual under CCD Flats Aid - its all explained there. Once the flat plan is populated and complete, clone it (in the plans editor panel) as a dark flat and off you go. LED panel over scope is fine but you may need to put some layers of paper or t-shirt between it and the scope unless you can adjust the brightness way down.
