Eskimo Nebula NGC 2392 "This Planetary nebula displays gas clouds so complex they are not fully understood and the gas seen in the picture composed the outer layers of a sun-like star only 10,000 years ago. The inner filaments visible are being ejected by strong wind of particles from the central star. The outer disk contains unusual light-year long orange filaments.

This short video show how to turn your laptop screen red without having to put any glass or red film in front of your monitor. This will help to keep dark vision during your observation / astrophotography / EAA session.

Thanks. Yes it is, and give us a great reward when we catch them.

thanks. the halos came after processing and enhancing

yes. i was testing, that's why i ended with 3 different increasing exposures and then mixed it. next time i will increase exposure and test. with this camera i'm limited in time because of lack of cooling.

Very good!

Thanks!

nice!

Yeah, lazy susan is very nice. Even in my set up completely modified as you can see in the video picture, it works very well. I was in doubt because of the lack of base, now i have the Y base but even with only 3 arms to support it it performance well. I had to add friction on each arm, you cannot see that in the pictures but that rubber band friction i add is enough to it. Each set up has its "particularities" 🙂 Observing at very high magnifications and framing with a ZWO224 and a barlow is an excellent test to the dob smoothness.

thanks. yes, those rare targets are the ones i like most

with my set up works wonderful. i have the lazy susan too but as i say in the video, no soap there. it works very well to, no lubricant on it. soap only on the formica path of teflon pads. level doesn't change. i suppose each set up is different and each one has to understand very well his own set up mechanics and act accordingly. what works well for one can work or not for other.

For observation, you know, the bigger aperture the better.

This is an easy, simple and very effective technique to help you to have your dobsonian base rotation always smooth. It is an ancient lubricant method of our civilization and i found on Cloudy Nights the ability to use it on the dobsonian telescope and since then i always use it successfully so worth it to spread the information.

IC 418 - Raspberry Nebula The planetary nebula IC 418 is a unique object in Lepus, a constellation that many of us might tend to bypass in favor of its prominent neighbor to the north, Orion. In larger instruments, this nebula exhibits a reddish hue that has earned it the nickname "Raspberry Nebula". 12" f/5 GSO on Geoptik Eq Platform ZWO ASI224MC Explore Scientific 2x Focal Extender Processed only in Pipp and Autostakkert nothing else Gain=500 Exposure=0,5s

very good!

Mine.

Thanks. Nebula is the forum rating lol Nickname is Astrocanito. Please note i don't compare other effective options and the premium lasers accuracy because in my method doesn't matter to have a premium laser. My goal was to have a balance between the purpose (achieve accurate collimation), budget, effectiveness and simplicity of use. That i achieved with this, using a crap laser that was going to trash and made it useful when connected to the concenter. So, cheap laser + concenter = budget solution, very accurate, very effective and super simple to use. The concentric circles help really a lot with the secondary adjustments and allow quickly detection of the lack of adjustment. This is not intended to depreciate other nice methods mechanics, this is the method that suits better on my needs to achieve accurate collimation.

You have multiple option to collimate. I use the european concenter connected to a standard laser.

This short video shows how fast and efficient a mirror cell fan can be getting rid of the dew. After a session i forgot to leave the fan turned on and the dew quickly assault my primary mirror because of the temperature difference inside. So i decided to record the important fan job.

1 day after this cleaning (so, today) i solved the GSO mess i show on the video with the mirror holder pads. So i took off the primary again to put some kind of foam stickers i bought to correct that mess they had. The new decent holder pads i put today on my clean mirror:

This is a photo taken after this cleaning and proper collimation. Against bad seeing and no cool down a nice dob with a cleaned mirror made the job.
