Ghost Sunspot?

Posted By Judson Mitchell
Space weather indicated that a sunspot was forming, then it disappeared. Was this counted? If so, it would have been another that the "ancients" would not have "seen".

The NGC-IC Project

Posted By Judson Mitchell
For some reason I am unable to access the NGC-IC Project page.

http://www.ngcic.org/

Has anyone else experienced this problem. It is an excellent source site for me and one that would be missed.

Why When the Moon is Full?

Posted By Judson Mitchell
We invariably get our good weather when the moon is bright or full. That suggests to me that somewhere else the reverse is true and they suck up all the good skies when it is dark. I want to know where that place is. There are witnesses to this.

Fan for mirror Surface on Solid Tube Dob

Posted By Judson Mitchell
Does anyone have any experience/recommendations/or other about mounting a fan on a solid-tube dob to blow across the mirror face? Seems it was discussed a while back, but I cannot resurect it.

Bahtinov Mask

Posted By Judson Mitchell
Recently made a Bahtinov mask for my 5" refractor but haven't tried it yet. Patterned it after posted images and made from heavy poster board. Not sure about the preciseness of the configuration, but suspect that it isn't that critical.

Para Corr Settings Non-Tele Vue

Posted By Judson Mitchell
Can anyone provide Para Corr settings for EPs other than Tele Vue? For example: 40 and 30 Paragon, 28 UWAN, Hyperions, Pentax XWs, etc.

Observing Near Natural Bridge Ky

Posted By Judson Mitchell
I will be vacationing near Natural Bridge KY during the Memorial Day Weekend (Sat-Sun) and was wondering if anyone would be observing nearby and welcome a fellow astronomer? Will bring at least my 1278 Burgess; hopefully the 12" Dob.

Let me Know.

Orion 80mm Short Tube-Amici Prism?

Posted By Judson Mitchell
Will the Orion 80mm Short Tube come to focus with an Amici Prism? It apparently is sold with a star diagonal.

Did anyone photograph the last sunspot. I could not see it on the enlarged Spaceweather videocam.

Complete NGC List!

Posted By Judson Mitchell
A while back I took several hours downloading and segregating the NGC list for my personal use. Then, due to a computer malfunction, I lost the whole thing. Does anyone know of a source listing the entire NGC that can be easily downloaded to EXCEL? My current option is to pick it up 100 items at a time, then cleaning it up for general use. Any help would be appreciated.
