Need help finding crater Ina.

[Doc]

I need help finding the number 99 feature in the Lunar 100.

I'm looking for crater Ina. I know it lies within or near to Lacus Felicitatis which I can find.

VMA doesn't have it neither does the LCA maps.

I really need a decent map to pin point this little crater.

VMA does show INA but doesnt name it, its co-ords are 18.6ºN 5.3ºE and i've marked it on the attached photo for you. Hope this helps

The best help i can offer is via this image by Wes Higgins. Crater Yangel is at bottom left, Lacus Felicitatis is above it, and to it's immediate upper right.

You'll notice that the right portion of Lacus Felicitatis is an uplift. Look at the top center of the uplift. Ina Caldera is the arched depression with the flat bottom.. like the letter 'D' laying on it's side.

Visually it would seem logical to look for it under a very shallow light angle, but an observer in South Carolina says he's seen it several times, all during a waxing Moon a few days after the terminator crossed the area. The window of opportunity is understandably small and (as expected), the seeing needs to be decent. Good luck!

Here's an image from Lunar Map Pro that may help. Ina is in the centre and you can just make out the name in yellow when you enlarge the image.

Hope it helps a bit.

Thanks guys

Carol is this Ina. Look at yellow arrow.

[Talitha]

Yes, that's it.

[Doc]

Well it's mine the next clear night.

[Talitha]

Go get 'em, Mick!!!

[Doc]

And I have found it. Located it with my 4mm Uwan giving me x457 and I saw a D shaped object, couldn't make out if it was raised or depressed. I could also see a couple of objects either hills or craters very near by Ina.

Thanks Doc et al, looks like you have confirmed it for me too, was looking for this tonight at 300x mag and just got a few hints of its presence as in Micks photo when the seeing improved

Nice one Mick

this was on my list last night but assumed it would be in Rukl and it wasn't!

I'll get it next time around!

[Talitha]

Congratulations!

.... not in Rukl.... SHOCK!! Well done on bagging it, this thread will be useful when I get to the end of the hard ones! 16" probably helped!

Cheers
