The discussion focuses on troubleshooting issues with an 8-inch Dobsonian telescope, particularly regarding the difficulty in focusing with a 30mm eyepiece. Users suggest that insufficient focus travel is common and recommend using extension tubes or a diagonal to improve focus. Observers note that atmospheric conditions and light pollution can affect viewing quality, especially for distant objects like Saturn. Collimation is emphasized as crucial for optimal performance, with recommendations for using a collimation cap or Cheshire sight tube for accuracy. Overall, the conversation highlights practical tips for enhancing the telescope experience and improving viewing results.

Perhaps Redbelly 98 has a good point. It may be better to purchase one than build. I'm am/was an engineer so I have this propensity to 'assemble things', and just assume everyone else does the same. Which is a bad assumption on my part.

Although, Baader does enclose directions on how to make a solar filter with their material.

I have used both the Baader 'milar' type filter and glass. I (and this is only a personal preference) preferred the 'cheaper' plastic filter.
I found the glass scratched easily and did not give the same 'white light ' clarity.

Of course you still have to be careful with the Baader film and not stretch or puncture it.

Again I concur with Redbelly98. If you purchase a solar filter be careful with it.
Don't take any chances with your vision.
Barbecuing ones retina is definitely not cool.

However, in fact I had my 10" scope out today with the solar filter on. I bought a new Canon camera yesterday and was trying it out. No sunspots though.


In Barlow lens I have three, a 2X, 3X and 5X. Out of those I use the 2X most frequent when I use a Barlow. I suppose actually the 5X is then next in line. I like to use it at times with the 32mm PLöSSL eyepiece.
Although, I don't think I would recommend a 5X for people just getting into astronomy.

Good EPs are expensive, so it's a good idea to choose a high-quality Barlow, and choose the multiplicative factor carefully so that you can get a wide range of powers with a modest number of EPs.

Could not have said it better myself. :-)
