Looks good!
The 500mm is lens? Or scope? What is the focal ratio (f/)?

a canon 500mm f4 IS lense lah..

so with a 1.4X and 2X extenders f4=>f5.6=>f11

like this

but on a wimberley ll head and gitzo carbon tripod from birding days. usually used for birds in flight shots, so good enuf for the moving moon.

In fact this gentleman uses 36 one-second exposures at ISO 1600 from a stationary tripod with such a set up to capture Comet Holmes

semalam di Planetarium Negara tak bawa camera. hajat nak cuba prime focus photography. blackout sungguh bagus untuk cerapan.

mymoon ganti. awan tebal tak sebaik semalam.



kalah 500mm.

cheers

[mymoon]

tonight the sky is not so good. can see only sirius so do one star alignment on sirius and slew to the moon. even mars is not visible. hope the sky will clear later tonight.




cheers

whew...astrophotography is more difficult that shooting birds. one would have thought that sky objects cannot run away, it would have been sup-sup swae.

Tonight after maghrib prayers spent 1 hour setting up the mount. set controller to EQ mode.first do a two star alignment. RA off , Azimuth off. redo a two star alignment. again RA off (better) azimuth off(much better). again redo; RA  off, Azimuth slightly off. redo RA-zero, Azimuth-zero. Do three star alignment. confirm RA zero, Azimuth zero. Mount aligned.

Was adviced by a sifu to recheck. Slew to Spica-  star in FOV . Slew to Arcturus - also star in FOV. Slew to saturn-spot on.

Replace telescope with the C8. Recheck. Slew to regulus-FOV. Track for 5 mins to check for drift. slight drift. Can see clouds moving in . So have to take pictures. Quick man. Answer nature's call. Attached the Canon 40D to the C8. Live view Focus on Regulus. Set the TC80N3. Attached the TC80N3 to the 40D. Slew to Sombrero galaxy. Beep.

Took 5X7min shots. Download to computer. stack and align using deepskystaker. nothing. check each frame- nothing. Panic can see clouds moving in. Slew to moon live view focus and adjust Tv took a shot. jadi.

Aiya forgot to change ISO to 1600. Murphy's law strikes again and by this time cloud cover over the zenith and so goes the Sombrero Galaxy (M104). Never mind next opportunity. taada rezeki. Must remember do a cook book for astrophotography. 

so gambar bulan juga kali ini.



cheers

Hi mymoon.

Don't throw away your M104 image. Although it cannot see in single frame. I would like to see it. Can you send to me?

Nak share a simple moon photo to you guys.

Hope you guys like it.

scattered clouds. fortunately where the moon is, the west has less clouds




Looks like the SCT is a bit soft on the RHS. Time for collimation?

cheers

[perseid]

More like the camera is slightly no place squarely on the focus plane. If collimation problem, it will affect the whole image rather than a particular corner.

The focus looks pretty decent. BTW, your whole Moon series rocks!
