A TOILET !!!!!!!!!!!!!!!!

Posted By Mark Holden
If the price includes shipping and handling, it's a bargain.

Otherwise, I'm sure the people on the ISS would much rather have some form of toilet than need to wear diapers.

Stellarvue F50 finder

Posted By Mark Holden
I've got an F50.

I'd say it does well in terms of bang for the buck. It's nice that you can change eyepieces and focusing is easy, but it's still a 50mm f4 achromat.

Personally, I'd like to see someone bring out a 60mm apo finder that would fit in my 50mm finder bracket.

Re: 140mm f/7.5 Notification

Yes.

I don't know how many people signed up at NEAF, but there weren't a lot of names on the list when I signed up.

PayPal question

Posted By Mark Holden
Paypal charges fees to the seller.

Many sellers pass these fees along to the buyer.

2" Dialgonal Recommendation

Posted By Mark Holden
I've had good luck with the Vernonscope 2" Quartz diagonal.

The drawback is it's not a dielectric diagonal, so you need to send it back to them for cleaning.

camera FOV?

Posted By Mark Holden
Your camera will give magnification about equal to a 43mm eyepiece.

The diagonal measurement of your negative is about 43mm.

Change to a Nikon DSLR, (or any aps chip size dslr) and it'll be about like a 28mm eyepiece.

Allow HOTMAIL and YAHOO on AstroMart

Posted By Mark Holden
It's probably better security than they get with the current system -

My impression is they intend to have the credit card replace the real email requirement - but other verification will stil be done.

If the credit card is no good, they'll undoubtedly yank the account right away.

I think it's a good idea - I'm not fond of yahoo email, but I know folks who aren't computer savy who use it as a way of avoiding viruses - yahoo screens all attachments, and won't allow you to download a file it decides is infected.

And I'm sure if the credit card/free email system turns into a problem, they'll get rid of it.

Allow HOTMAIL and YAHOO on AstroMart

Posted By Mark Holden
The main difference is if the change is made, you would have the option of using a Yahoo, hotmail, or gmail email address for your account, if you were willing to pay the $12 verification fee.

The $12 fee gives AM some support, but mostly it gives Herb a chance to verify a credit card you provided is valid - implying you're who you say you are.

If you choose to keep your current email address, you won't need to pay the fee, and the only difference you'd notice is some folks who you deal with will have email addresses that aren't associated with their employer, or their ISP.

It seems like a good idea to me because some folks do have valid reasons for using the "free" accounts.
