  1. So start with an affordable (but decent) dual-narrowband filter ASAP, then try to modify your DSLR when you can. I agree that the astro OSC cam is better than the modded DSLR, but as you can see the DSLR can also satisfy you. 

    Some cheap dual-narrowband filters may bring halos around stars, but it's up to you if you accept them or not.

  2. I use two Xbox 12V 16A PSUs from ebay to powering my CGX + NINA setups and EQ5 OnStep mod + ASIAir setups. 16A is safe enough, I never regretted this choice. Some electrical skills and tools are needed to adapt them to individual needs. There are a bit newer PSUs offering 14A which is still more than needed. My CGX setups contain everything typical excluding a motorised rotator, but I power also a flat panel from my AstroPC. ASIAir also powers the flat panel.

    Edit. 

    Recently I bought a Jackery 500 portable power source. I tested it with the two fully working setups at the time powered from 12V outputs - it's ok for one night, no more.

    The filters are not, in my experience, the primary source of dust bunnies.

     

    I did not need to open my 7x2" filter wheel for nearly half a year. Once I needed to unscrew my 2600MM the dust moths appeared immediately. So, I can rather confirm the above. Also, the dust has a little chance to land on the camera if playing with it is unnecessary. Even with that, I do flat frames for each used filter after every session. :) 

  4. Another step towards a comfy Solar System observation. Not today, on Saturday morning I received a great RACI finderscope from @Hairycamel. It's much easier in use than the original straight finder, especially if have to aim higher. I'm not sure whether I'll replace my Baader T2 prism with Amici one, I'll use it as it is for now. 😊

  5. The first thing to consider in the beginning of reasonable imaging is the mount, particularly it's accuracy and maximum load capacity. If it's neglected in the beginning it often comes back after some time, when you want to buy another optical instrument, which usually is heavier.

    Just compare specifications of the AVX and GTi.

  6. Hi,

    That's very good start!

    Find out how to aim at exactly the same point and add more data to the same project. At least ASTAP offers multi-night stacking (light and flat frames). 

    The SHO is strongly green, but when you equal the channels it becomes less green. Also, Siril offers a photometric colour calibration. You can play with selective colour correction offered by many programs like PS or Affinity Photo, I hope Gimp also has the features. I don't like the green in SHO too, so I play with sliders... 😉

    Good luck

    I always reassure new parents that the first 28 years are the worst 🙃

    Grandchildren are so much easier,  you can hand them back.

    Regards Andrew 

     

    Can the 14 and 13 just summarise to get 27? It would be so close... 😂

  8. Congratulations from me too. 😍

    I experienced it twice, 17 months of difference. Sometimes I felt like I have three, not two... 😁 Now they are 14 and 13 years old and I cannot wait when they are responsible and self-sufficient enough to let me spend night under sky darker than Bortle 9. 🤔😉

  9. Indeed, it's really good picture. You are stubborn and don't give up, I like it. 😁 👍

    I would suggest creating a mask on the stars, inverting it and reducing a colour saturation of the background.

    I did 10 Dark Frames Same exposure and ISO,

    I think the mount performed pretty well but It's my first mount so no frame of reference. 

    Indeed, good star shape, even if without guiding. 

    Use an opportunity of bad weather to make 60 dark frames of each exposure time and ISO you think to use. Also, 60 bias frames. 30 flat frames after each session should be enough. 

     

  11. I'm pleased to present my most recent image: The Lion Nebula (SH2-132) in SHO palette. This image waited two weeks on my AstroBin page. In the beginning, I wasn't sure if it was good enough or maybe I should upload another release, which I usually do. A few days later I still wasn't sure... whether I could be proud of a Top Pick award or maybe I should wait for something better. Well, it looks like it's too early for the Image Of The Day, maybe next time. The Top Pick must be enough for now. 😄 😊
