This is an alert for anyone who has or is thinking of purchasing a ScopeDome.
The problem started with the 8A fuse on the main controller board blowing. The fuse was replaced and then it blew again after several rotations of the dome. The 220VAC power supply also sparked and smoked. If I had not been in the dome at the time, there could have been a fire.
I suspected that the brown and white wires were shorting. I was correct. I removed the covers and exposed the rollers and wiring. I was “horrified” at what I discovered.
The metal plate that the rollers ride against had completely worn through. A piece of the metal plate (brown wire) was touching a metal post (white wire) and shorting together. EEK!!! I managed to cut and break off the existing metal plate where it had worn through.
I sent the photos to ScopeDome. I already knew what the response would be. I was blamed for adjusting the rollers improperly. I adjusted the rollers to remain in contact with the metal strip, but still allowing easy movement of the dome with one hand. Obviously, that was not the correct way to adjust the rollers. So, what is the correct way?
I was told that ScopeDome has 40 domes of this model around the world and they have never seen anything like this. If that were correct, one in forty is not very reliable for a product of this type. The dome is less than a year old.
I was told that ScopeDome would replace the thin metal strip, but I would have to pay the shipping costs or have one machined in Japan. The problem with that is that the nuts that secure the bolts holding the metal strip are inaccessible. ScopeDome suggested that I cut holes in the fiberglass ring cover to remove the metal strip. That's ridiculous! Not only would that look awful, it would create way for water to enter the dome.
The metal strip should have been secured with bolts and nut plates instead of nuts. I also suggested that ScopeDome make a roller that uses spring tension that rides on top of the metal strip instead of gouging it. That way a customer can not misadjust the roller. ScopeDome responded :
“We realize that the dome is not a perfect construction but it is compromise between functionality and production costs.”
Currently, I have a dome that does not work, and a bad power supply. I do not see a solution except to disassemble the entire dome and start from scratch. This would also require that the telescope and all of the electronics be dismantled.
Please take this into consideration before purchasing a ScopeDome. If something goes seriously wrong, you are in trouble. Poland is a long way from Japan, and ScopeDome was very quick to point that out to me when I asked for help.
I'll update when the situation changes...hopefully for the better. George

Instead of posting three blogs, I decided to throw everything together. Alright then, here’s some photos of the built-in pantry shelves I’ve been working on these shelves for the past few weeks. Before the paint even dried, Erika was already stocking them.
The sliding door into the pantry was also painted along with the trim. This was required because the original bare wood door would attract mildew in the hot and humid summer. Eventually, all of the interior bare wood doors will be painted. I like the finished look...it's very American.
In an effort to stay healthy, we have been drinking smoothies made from various fruits (banana, blueberry, pineapple) and vegetables (komatsuna, carrot). It tastes great, but the color of smoothie is a poop brown…not so good. Well anyway, it’s supposed to be healthy. Cheers!
The next project on the endless list of things to finish on the first floor is the entryway. The closet will be changed into an area that is a walk-through. The main reason the area is being remodeled is because it has no floor. I don’t know why it was built this way in the first place. The outside vent lets freezing cold air into the house. I will install a new floor and finish the walls. I'll also add some built in lighting. It should open up the entry area, but stay warmer in the winter.
This is a view of the underside of the stairs.
I'll need to coat the bottom of the stairs with some paint. Then I'll cover the bottom with plywood and wallpaper.
We’re really looking forward to getting the first floor done this year. George

After a couple of adjustments (failures) since my last sourdough post, I think I’ve finally found a reliable and consistent way to make and bake bread in a wood stove. Here’s some things I’ve learned:
1. It’s not as easy as some internet sites claim. Making a loaf of sourdough bread is not hard, but it’s not easy either. Expect to fail…many times.
2. Don’t be afraid to experiment. Eventually you’ll find the right amount of ingredients.
3. The starter is on its own schedule. When “its” ready, that’s when you bake…not the other way around.
4. Kneading is not required. Just mix the ingredients, cover and let it rise.
5. Place the dough in the oven and leave it alone! Find something to do and forget about the bread until it’s done. Don’t be tempted to peek. Every time the wood stove is opened, precious heat is lost. Unless another fire is started, you just lessened the chances of a successful loaf.
6. Baking bread is really frustrating. Make sure the starter is active, the brand of flour is the “good stuff”, keep the proper wood stove temperature (450F), acquire some knowledge of the starter (when to feed, rise times, when to bake), have a patient spouse (you’ll waste a lot of flour).
As I write this post, I’m eating the best bread I have ever tasted. Isn’t that worth the frustration? You bet it is…yummmmm.

"Most" of the calibrations are completed. The imaging train is robust and reliable. CCD Inspector shows that collimation is required, but almost no tilt exists in the imaging train. The Edge optics are providing a nice flat field. Seeing has not been very good and trying to lower FWHM has proven to be a challenge. I believe after collimation the numbers will improve. However, that will have to wait as the dome gets very cold at night this time of year.
I have been imaging Caldwell C30 for a couple of nights. The darks, bias, and flats have been integrated in PixInsight. Stay tuned for a first image along with a description of the target.
I’m having some trouble with getting LUM flats that aren’t distorted. I’m using a light box and the RGB flats are acceptable. The QSI CCD requires flats that are approximately 35700 ADU’s. I’ll need to get this worked out before I can move forward with the processing.
Sorry for all the technical jargon, but every once in a while I’ll throw in a post like this to interest the astrophotographers reading the blog. Believe it or not, there are quite a few of them lurking out there. Your comments are always welcomed! George

We enjoyed having guests stay at our home over the weekend. It was a pleasure to have the house filled with laughter and conversation. I want to thank everyone for coming!
Two boys experienced riding a tandem for the first time. The tandem was quite a spectacle in this village. Tandems are very rare in Japan. I was exhausted after two laps around Tsukahara.
Pizza for the dinner...10 pizzas to be exact. The girls are learning how to roll pizza dough.
Everyone had a chance to toss pizza dough and add toppings to their pizzas.
Playing darts was a big hit with the kids. They put plenty of new holes in the wall!!
Mr. Ito, a successful business owner, enjoyed making crepes. He's really good at it! We also had waffles and real maple syrup.
The kids tried to beat Lucky at playing soccer. The youngest, Daichi, played better than all of the senior high school kids.
Only Lucky was supposed to hitch a ride, but the "city" kids were tired of walking. The adults ended up walking with Kiley around Tsukahara.
Chi-chan helped Erika with preparing breakfast early in the morning. Thank you Chi-chan!
Note: Erika did the editing of the photos.
The boys ate a lot.
It was a great time! The kids experienced an overnight stay with us and we hope it was memorable. Hopefully, everyone learned something!

Erika did some research and discovered a great idea…baking pizza in the wood stove. We decided to give it a try. She ordered the stand and pan on the internet.
We have been baking bread for almost a year and the bread maker does an excellent job making pizza dough.
The flour we are using is from Hokkaido. I find that Hokkaido flour rises a lot more than the other brands I have been using. After the dough was finished in the bread maker, Erika let the dough rise. Then she tossed the dough like a pizza chef (She wouldn’t let me take a picture) and added all the toppings.
I placed the stand in the oven along with the pizza.
A few minutes later…pizza!!
I’ll be trying to bake sourdough bread in the near future. Stay tuned. George
