I'm excited to get it done, will be a several month long project, building it in stages as my schedule allows. Likely won't get the warm room put in till the fall, but will still be functional. Not a whole lot more progress, finished the with the floor joists, stacked the rest of the pier (still needs sealant on sections above pier floor), and installed conduit for pier electrical and data to the eventual warm room location. Unfortunately injured my knee while painting the subflooring, so taking it easy for the time being. https://www.AR15.Com/media/mediaFiles/158414/62137615_2398251773741650_8731960278486351872_o__1__jpg-969217.JPG View Quote View All Quotes View All Quotes Quoted:

Sweet! I wish I had open skies like that. I finally got my scope back, just need to get everything set back up and test out the optics. I also bought a Skywatcher adventurer for travel shooting, but havent played with it yet.

Care to explain your setup? Any advice/information for a newbie?
I use my mum14 for stargazing and am fascinated, what you're able to see is on an entirely different level. How do I got about getting into it? |

How do I got about getting into it? View Quote Images above were with a Canon 70D on a tripod w/50mm prime lens pointed sort of at big dipper, couldn't see through eyepiece, so sort of SWAG on aim by putting binoculars seeing big dipper on tripod, noting angles, then putting camera on and making it sort of match direction/angle. I was a bit high and to the right, but the big dipper did move more into frame after 15 minutes. The nicer photos in this thread are with mono cameras, filter wheels, 4"+ scopes (seems Schmidt-Cassegrain are common), and tracking adapter on equatorial mount, none of which I have. Start with a par of 10x50 or 20x80 binoculars for $200 or less and you can see a whole lot. Once you can spin around to different stars and aim, you'll get a better feel for aiming a telescope where you have not much of a clue what you might be looking for is located. I actually like binoculars better than my son's Celestron scope since both can see planets, his more clearly. Nebula and galaxies are slightly fuzzy and different colored dim stars, but visible with both telescope and binoculars. To get galaxy photos as seen in thread, a lot more light gathering is needed, and about the same amount spent on tracking and mount/tripod and camera in addition. So, $2-$6k seems to be the window from my casual browsing of prices. Though that upper number is the 'beginner setup" upper number, it's like saying an AR is $500 to $1500 depending, and nobody stops at just one $1500 rifle. |

Zach540's observatory build pictures motivated me to do something today on my own dome project. Today was a nice cool day, so I decided to dig the hole for the pier. The only place that works in my back yard is in the center of my garden, which when the dome is placed, will look pretty nice. I can then finish up the sandstone. The pier is 7" diameter x 7 foot long by roughly 1/4" thick. The pier is almost 4 foot in the ground, so I did not pour a footer, I really don't think it will need one. I will be pouring concrete around the outside of the pier and using a tamping bar to compact the concrete. I'll then fill the tube with concrete. After the concrete cures, I am going to tig on a round plate that I can bolt the pier plate for my mount to. This thing isn't going to go anywhere. It should be very stable. https://i.postimg.cc/6pdRGHHL/IMG-20190609-165232-01.jpg View Quote |

My first test of the Skywatcher Adventurer Pro with a Canon 5D MKIII. I was camping with a bunch of arfcom guys and was pretty well into the beer and whiskey but I still think this came out alright. https://i.imgur.com/YmPtbD1.jpg I need to try fixing some of the noise issues, this camera will really need a master dark and bias to help. The other thing and this is going to end up being a problem is there is no way to dither with this mount, obviously its just a small travel mount and so it has limitations but dithering is an absolute must. There is a shit ton of correlation noise in this image. Overall I like it, but I need to find a way to dither. View Quote Does it look like Explore Scientific fixed the scope problem? |

View Quote Are you looking for a way to dither without using a laptop connected to the ST-4 guiding input? That would have to be total manually controlled dither wouldn't it? It looks like the Skywatcher Adventurer Pro has a ST-4 auto guider input that allows RA only guiding. I use a free program called APT (Astrophotography Tool) for my image capturing, it has an option called APT Pulse Dithering for dithering mounts that are self guided (SkyWatcher StarAdventure, AstroTrac, etc.). But APT does require a computer and interface to the mount to run. If I remember you are using SGP for capture, does it have a dithering mode for self guided mounts? |

To the guys that know what they're doing:
Is there an easy way to remove the orange light pollution from an image? I tried a few more of the moon, one turned out OK other than the orange background, and removing the orange by making it black and white and changing contrast doesn't work when there's the moon craters using a lot of that contrast to look pretty. |

It's a very bright object, so no special technique needed. EXIF for that shot is 600mm, 1/160, f/9, ISO 400. D500 and the Tamron 150-600. I do shoot from a tripod, mirror-up remote, with electronic front curtain. The EFC is probably overkill, and shooting handheld isn't hard, but I like the tripod. I then run it through Lightroom for crop, levels, sharpness, noise, etc. Here's the frame out of the camera: Moon 20190611 OOC by FredMan, on Flickr |
