A pair (yes a pair) of 6X7 2X rear converters came in the mail today.
One was in "ugly" condition and was $9 + S&H. It's not ugly enough to strip the glass and make an extension tube, which was my intention. So, it's dark outside, the moon is up, and I have this 300mm/f4 6X7 lens and a pair of TC's

Here's a link, not a crop. (I forgot to clean the sensor today)

and a scaled down, still full frame as shot, with fringe, sensor dust and all

Taken with the kluge in the second photo:
That's 1200mm/f16 for those poor with math

Amazing. Thanks for sharing Rocket.

Tonight here in Indonesia and some other parts of the world, there will be a total lunar eclipse. I've ordered a Hanimex Teleconverter 2X and will be paired with my 55-300 to capture that moment. But it's still on it's way. I've checked the tracking number, and I suppose received it yesterday. I'm still crossing my finger, hoping by this afternoon I received the package.

I'm planning to use my macro extension tube, if something bad happens. Do you think it will work out?

I've never shot an eclipse direct. I projected one on to a poster board way back in the 90's for my daughter's school. about 20 inch diagonal. Was pretty impressive.
Maybe some expert could give some advice for your shots.

Isn't package tracking about the most exciting thing ever?

[br19htside]

Wow... 1200? I wish I have a chance to be that extreme because as for now I could only reach 600.

Btw, it's here, the TC. I grabbed the package from the mail man (said thank you), took scissors and brutally unpacked it.

I hope I can post something later on. Wish me luck.

Good luck with this. I look forward to seeing the result too. At least with lunar eclipses you don't need to worry about your eyes.

Here's hoping it turns a nice blood red for you.

how heavy was that setup? thanks for sharing the sample from that beastly setup

[Rocketvapor]

The 300, 2 TCs (one a Pentax, one a Vivitar), the 67 to K adapter, the K-r, complete with battery, strap, and SD card, and a Giotto QR plate is a mere 7 lbs 7 ounces. I need to make an aluminum extension to balance it a little better on the tripod mount or make a ring to put around one of the TCs. The moon shot was just a lark to see how the combo worked and was propped up on my car to stabilize it. I don't remember the aperture, maybe f5.6 to f8 (on the 300mm), 1/90 sec, ISO 800.

I'll play with this some more but don't really expect anything all that great.
You have to feed this thing a lot of bright light

Agree

Here is the shot that took last night. Stayed very late until 5 am, slept for 2 hours, and went work.

Forgive me if the result is not that good. Still learning a lot of things, including Photoshop.

Oh nice! The moon was stunningly bright last night where I am, but I'm on the wrong side of the planet for the eclipse. Thanks for sharing.

[Rocketvapor]

Yes, I like.

You are very welcome...

Yes, I like.

Glad you like it Rocket...

I shot the moon with a K-x and a 135mm coupled with a 2x teleconverter. This is an 95% crop.

[akanarya]

mkvlln
nice shot, which 135 and x2 you used,
did you stack or a single shot?

[mkvlln]

single shot. I used the takumar 135/2.5 bayonet and a vivitar 2x teleconverter.
shot at f/9, iso 100. On tripod of course, haha.

how do you stack images?

i think good performance.
for stacking, multiple shots taken , say 10-20 shots,
then they are combined with stacking software.
This process increases details,
registax is well known freeware.
