Hi Shoshana, I know almost nothing about Dibs, but I feel that coating is pretty much necessary. I read that silver coating gives 95 percent reflectivity while aluminum coating gives 90 percent. I think aluminum is most common and works well. Here’s a discussion about fans: http://www.fpi-protostar.com/bgreer/fanselect.htm Best wishes, Joe Sent from my iPhone

Telescope purchase questions (Truss tube Dob with go to and tracking)
Hi everyone! Well, if there are no more stars, I'm retiring, lol. j/k
So, I'm in the market (so far at this time) for a go to Truss Tube Dob with tracking. (for the purpose of OBSERVING....not photography)
With less experience than you folks, I am asking anyone who can assist me some questions:
1. Mirror quality (what should I look for)....noticed some are 'aluminum coated for brighter images'. Etc...., some have fans, etc. 2. Go to programs. Companies have different software.....synscan....etc. Wondering about reliability also....re: tracking 3. Looking for a collapsible one....so larger sizes ok. Seems like some have a counterweight option and a more minimal base (not like heavy disks as Lightbridge) 4. What company is the most reliable with good customer service? 5. Some of the newer trusses look great but don't seem to have go to. 5. I'll be watching Memorial Day sales, been watching Cloudy Nights..... 6. Not in an extreme rush.....wanting to get good quality at a good price (doesn't everyone?) 7. Will also add a telrad or finder
I might be able to carry 70 lbs on my back, lol
Thanks for your time and attention:)....again THANK YOU All the best, Shoshana
If there is a local rep who can explain features and benefits and compare across vendors, that's an idea also:)
