1. If the wire to a pair of 12v DC batteries in series is 10AWG (5.3mm2) and is say 2m in length, what gauge and length wire should join the two batteries, or as long as it is at least 10AWG and less than 2m it is unimportant? Are there issues with using thicker wire to join the two batteries together.
2. And if these two batteries were in parallel, what are the requirements of the wire joining these two batteries together? Again, is using thicker wire than the live and positive to the battery pair problematic?
3. And if you can tolerate answering another question, where would you fuse these two set ups?
I tried searching for some easy deep sky objects on the internet but I never got a staright answer. Could someone please name some easy targets that I could use tonight. Mostly in Canis Major or in Canis Minor if possible. The deep sky objects that I am trying to find are quite simple. That can be seen by binoculars. Thanks, any help would always be appreciated. 😀
I'm trying to get back into astronomy (had a Meade DS 2090 Mak when I was 10 but was too young to get into it) and I'm having a very hard time choosing a telescope.
My main goal is to observe a bit of everything. Planets and the moon are great and I definitely would want to observe them, but my main focus would be DSO's. That being said, I would also like to have the possibility of doing some basic astrophotography afterwards. Not expecting to do 2 hours of long exposure and getting some insane images, but having a telescope (or rather a mount?) that can track would be nice to get some decent images. Basically, visual observation is a must, AP would be great but only basic, no need to get one JUST for that. I realize that visual observing and AP are 2 very different things, but my question is if it is possible to find something that is mainly used for VO and is somewhat capable (even if it's not great) to do AP with. Furthermore, a push to or goto would be fantastic as well since I'm not too familiar with the night sky. Is it really difficult to find DSOs yourself without reading and learning for hours and hours?
My budget would be around 800 euros, that is everything included, telescope, mount, eyepieces etc... (If it's a little bit more than that that's fine as well).
After hours of doubt and searching I thought the Orion Skyquest Xt8 Intelliscope would be good (push to) (around 750 euros), however being like most dobsonians, this one wouldn't track. This made me think :
Should I rather look for a newtonian reflector with an EQ mount, or just give up my basic AP wish and go for a dobsonian that doesn't track? Some people have suggested to drop AP for now and go for the dob, is there a possibilty to upgrade later to make the dob work for AP, like putting it on an EQ mount, or would I have to buy a new telescope again?
Any telescope, mount and added equipment like eyepieces and filter suggestions would be reaaaally appreciated, cause everything just feels overwhelming and I don't know what to look for anymore.
Thanks in advance!!
Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.
So I'm having some issues recently and have a lot of questions for the erecting eyepiece 1.5x. I want to know if they are useful, better, and i also want to know if they have a lot of detail in them. How do you use a erecting eyepiece? What is it for? When can i use it? Also my issue is when I try to use an erecting eyepiece on a star it is out of focus and cant seem to find the right focus. yesterday I had tried on sirius but it just showed me a huge ball of light. Any help and tips will be appreciated.
