Some quick moon images from last night, captured with BackyardEOS using a Canon 70D through the MN190.
Two images of the moon taken last night: the first was captured with the Atik 314L+ through the ED80 using a hydrogen alpha filter. This filter helps to reduce the effect of atmospheric disturbances and tends to give very sharp images. It’s a stack of 32 separate exposures aligned and processed in Registax 6.
The second image was taken through the MN190 using the Atik 460ex OSC, and is comprised of 12 individual exposures, also aligned and processed in Registax 6:
The two images below show the moon just after first quarter, with the sun rising over Copernicus. They were taken in the early evening sunshine while the sky was still bright blue, but by using very short exposures through a hydrogen alpha filter, the background sky can be cut out fairly effectively. Taken with the 314L+ through the MN190, each is a stack of 12 frames aligned and processed in Registax 6. The first image was exposed for the whole of the lunar surface; the second was somewhat over-exposed to capture more detail on Copernicus itself.
This is a mosaic shot of the moon, just past first quarter. Taken on an Atik 314L+ through a hydrogen-alpha filter, each half of the mosaic is a stack of 20 x 0.06 sec exposures. The two halves were aligned and combined in Registax, then stitched together, the final sharpening was performed using wavelet processing in Registax. The combination of a hydrogen-alpha filter and wavelet processing has resulted in a very sharp final image.
This image was captured some three days after full moon, using the Atik 314L+ and MN190. The whole moon was too big to capture in one go, so 10 frames of the northern half were taken followed by 10 of the southern half. The groups were combined separately in Registax, and then joined together using Canon Photostitch software. The moon was also too bright to be able to use a standard luminance filter, even at minimum exposure time of 0.001 sec, so for these frames an Hα filter was used, which gives the image a nice contrasty quality.
The image shows Mare Serenetatis, with the crater-within-a-crater Posidonius in the centre of the image. The crater Archimedes is right in the middle of the left hand edge of the image, with Aristillus just above and to the right. The lunar Appenines, Montes Appeninus, run up the picture just to the right again.
