Newtonian spiders
The eight legged kind !
I had a good look inside the mirror box of my SDM truss dob today and found a heap of fine cobwebs all over the place. The mirror is due for a wash so while its out, im thinking of giving the inside of the mirror box the baygon treatment.
Any reason I shouldnt?  Anything else I can do to keep the blighter's out other than seal the mirror box up completely?

Nooooo . I wouldnt use baygon might accidentally get a few spits on the mirror surface which can also eat away the top coating. Use water (destill water) and put it in a spray

Just remove the secondary, then spray a little. I use surface spray along the mount legs, and some areas inside the scope.

Mosty any of the synthetic pyrethroids will work at relatively low doses. They can kill spiders but should also offer some longer term repellency.
Since they break down in sunlight, they should last a long time (months) "in the dark box"...depending on the product that you use.
Do make sure that your mirror is out of the scope...the "propellent" for the spray will likely be hard on your mirror coatings...
Good Luck!

My mirror hasn't rotted away, so it all looks good

Didn't one of those big refractor observatories in the USA have a spider problem at one stage , had the observatory technos really worried as they though the glass was buggered, took them months to eventually send someone up the tube to take a squiz at the back of the glass only to find it covered in mumfield spiders and their webs , who had , poor little critters , starved to death.
I guess they were "passing bricks" until they found it was spider webs and not cracked glass ....

Ahh good, thanks for the update Geoff,
wouldnt want to ruin that very nice SDM. Your radar must have pinged as Jen is updating herself on my funny posts and this one has been sleeping for a while.
Cheers

You are confused , those would be tree funnel webs , not tarantulas.

The tarantulas I know, do. So do the tree funnel webs
Although, the worst thing to get to you are the Newtonian Drop-bears. They're worse than them all!!!!
