Ghost of Jupiter Nebula NGC3242 - Hydra Constellation
Tiago Ferreira replied to Tiago Ferreira's topic in Imaging - Deep Sky
Thanks Peter. I like planetary nebulas a lot. -
yes, may be out. Thank you to warn it. I really was focused on testing the reducer with different adapters and changing a lot to see the different results. Also changing with focus extension to check and also with an eyepiece. The thing is i was testing and i wanted to measure differences to check if a parfocal ring will work and the aprox. distance between cam and EP. As it was horrible seeing my intention was not to get a perfect picture, but testing. I don't have a bahtinov mask, i'm too lazy to add it to my set up, i just make simple focus hand adjustment and usually works fine. Of course at the end i was playing with processing and like the result to share. I'm sure i will do it again and next time i will centre my attention at focus. PS: and i also will pay attention if the reducer has some impact on that, i don't know.

My 2nd photo of the M42 - Orion Nebula. It was the first time that I tested the TS Optics 0.5x reducer on the ZWO ASI224MC. As expected, using a 0.5x reducer in this cam, coma appear on the edges so I cut around it to be less visible. Anyway I am satisfied because with the reducer I can increase the frame in this camera for larger objects. 12" GSO Dobsonian Equatorial platform Geoptik Eartha ZWO ASI224MC Camera TS Optics 0.5x reducer Processed by DeepSkyStacker and Photoshop

Collimation with Concenter eyepiece
Tiago Ferreira replied to Corpze's topic in Discussions - Scopes / Whole setups
question: alone with the barlowed laser can you collimate turning the knobs at once and finish the process? without having to stand up and down, up and down, until see that the dougnut fits the barlow paper?- 23 replies

Collimation with Concenter eyepiece
Tiago Ferreira replied to Corpze's topic in Discussions - Scopes / Whole setups
yes, i believe you. but i may never test an expensive laser, they are, well...too expensive to achieve the same results i have now. And there was a time i was prepared to buy those expensive ones and put mine in the trash. Almost did it. Until while looking for them i found this concenter and "cooked" this powerful "fusion" with my cheap laser. My message is: you can have perfect collimation with a cheap laser and a concenter. Someone that already has a concenter and a cheap laser in a box, just try my method.- 23 replies

lol yes it is. Could be. It has 2 strong forks that stick the rocker to the platform and i'm not sure if i put it right on the video at first time. Usually i look down to check it but here i didn't. If not well fitted, when touching, at some time later it enter the hole(s) and stick that's why i always check if it's properly fitted. It happen before. And then with the set up completely unbalanced with the heavy cap on top didn't help, yes could be my mistake on placing it. When i'm in my daily regular use that tilt doesn't happen. But also i do things nice and steady and check it, also with a properly balanced set up. In videos i made after this one, in which i also have the platform it doesn't shake at all. Like the one where i talk about balancing the dob. There you can see a lot the difference lool :

Collimation with Concenter eyepiece
Tiago Ferreira replied to Corpze's topic in Discussions - Scopes / Whole setups
I had already a cheap laser and a concenter which (only) with this method gives me an excellent result. When a team is a winning team we don't change it. This applies to all of course, i show my new method to help people that struggle, the ones that don't have problems just stick with their own method (also a winning team). Also i realized there is plenty of people using cheap lasers, convinced that they have the scope collimated and it is not for obvious reasons, so my video also expose that issue for those to check it and find the facts. Also i give a solution for that without the need for extra and expensive tools (well, except the concenter which is a must have). For last, i really prefer my method because depends only in the concenter (not the concenter + another tool) and as long as one knows how to use it it's perfect. And we save those poor crap and cheap lasers from unemployment eheheh cheers.- 23 replies

Collimation with Concenter eyepiece
Tiago Ferreira replied to Corpze's topic in Discussions - Scopes / Whole setups
Great video Daniel, it helped me to find and understand this wonderful effective and simple tool. Not many people using it i suspect because it's manufactured and invented in Europe and we unfortunately have loads of obstacles to buy from US and them from buying to us. Well, i created my own method which boost the potential of the concenter. Sooner or later people realize that lasers aren't good to collimate (even if they are collimated). Just have to align all and then mess with the focuser screws or move around the laser to see all messed up again. Fortunately i quickly realized that and since then i just use my own system that i can assure you that works like a charm and i just check collimation before observations and have it almost all the time collimated or moved 1 or 2 mm that i adjust quickly. And guess what? I also use my crap laser to collimate, yes. If you have a crap laser please check my video before throw it to the bin. You will need a concenter and any laser. A concenter is a wonderful european tool that you can buy easily on Europe and super efficient and easy to use. This is not a regular method that use a concenter then use a laser like 2 independent tools. This is a method that use a concenter secundary collimation and then you MANUALLY ADJUST a laser dot at the primary mirror TO THE CONCENTER JOB in order to obtain the full collimation as a hole. It's a concenter and laser INTERACTION that allow a cheap laser to be used with an accuracy it doesn't have by itself alone because it relies on the concenter accuracy.- 23 replies

A very effective and simple way to balance your dobsonian telescope using a set up combination of bungee cord, magnets and chain. This triple system allow to move the COG - Centre of gravity of the telescope where it should be to get a smooth action observing or astrophotography use. In this video i'm using my 12" inch GSO dobsonian newtonian reflector. Thank's to Cloudy Nights starman who gave me the bungee cord idea. https://www.youtube.com/watch?v=GKEMIgEUF9g

My first EAA attempt - Eskimo Nebula (NGC 2392)
Tiago Ferreira replied to Tiago Ferreira's topic in EEVA - Reports
No i didn't. I use the telescope almost every night but for visual. Next time i connect the camera i will search for it. -
My first EAA attempt - Eskimo Nebula (NGC 2392)
Tiago Ferreira replied to Tiago Ferreira's topic in EEVA - Reports
lol it's a start. next time i will try to push more, I'm still learning sharpcap. the geoptik platform is very very nice and stable, I'm glad i invested in it instead of more eyepieces, etc. -
My first EAA attempt - Eskimo Nebula (NGC 2392)
Tiago Ferreira replied to Tiago Ferreira's topic in EEVA - Reports
my intention with EAA is to make the colors and other details jump and it works. it is to use sometimes because i prefer mainly visual all the time. -
This was 4 days ago, my first attempt with live stack on sharpcap pro with Eskimo Nebula (NGC 2392). As a first attempt was a mess, like riding with closed eyes, and not really knowing what i was doing but the funny thing of this is that i'm sure in the future i will see this post with a smile in my face 12" GSO dobsonian on Geoptik eq platform ZWO ASI224MC TotalExposure(s)=2 StackedFrames=1

In this video i show with detail how i moved my primary mirror to get inward focus for filter wheel, focal reducer and astrophotography zwo asi224mc camera. This was made in my 12" inch GSO dob and solved all backward focus issues allowing me to use all kind of things with my telescope. It's a good modification to do in this kind of telescopes. https://www.youtube.com/watch?v=zmuaacN_NRU

My first Ha image Horsehead Nebula (under 70% Moon)
Tiago Ferreira replied to fifeskies's topic in Imaging - Deep Sky
great picture, natural hint -
This is my easy method to help anyone that find the objects and then struggle to frame it with the camera, specially small sensors cameras. With my technique, with any additional tool you will have strongly reduced the time between finding the object and push the record button on your laptop. Worth to watch. https://www.youtube.com/watch?v=AQrkd-3k2nY

It was a good night and i choose this Snowball nebula (NGC 7662) which i think it also has to be with this winter season. A beautiful planetary nebula that i like to observe and with the camera we can see even more detail and color. The sharpcap action is just the basic but you can see the eq platform action which was good even with a 488x488 frame. Also how to find the object in Skysafari Pro 6. I would like to enhance the "finder adjustment trick" i use to find the object with the camera, which has a very small sensor and a 2x barlow attached making hard to frame the object (however visually with an eyepiece is easy to find). Hope you enjoy:
