Full Moon Images

[peter_4059 (Peter)]

I had a bit of an experiment with imaging through an old 70-210 mm SLR lens on Sunday night with the Neximage and the DSI II. The DSI II was shot through a 2x barlow in addition to the zoom lens. I think I've gone a bit too had on the wavelets on the neximage pic but prefer this to the DSI lines. Not sure what causes these?

Hi Peter

A nice pair of images – well done. What make is the 70-210mm tele?

I was wondering if the “lines” are the Bayer matrix structure. I once had a similar effect with my DBK (colour) CCD when I set it to B&W mode.

Cheers

Dennis,

The tele lens is a Zelar 58mm aperature that I've had for more than 20 years. I have the mono DSI II so don't think it is Bayer matrix related. I have seen threads refering to interlace correction. I thought it might be related to the design of the CCD chip.

Nice images.... if you have photoshop - you can deinterlace the pic, removes these annoying lines.
See this thread for deinterlacing info....

both images are good except the first is much much sharper than the second one.

Lee,

I don't have PS. Do you know of any other de-inftrerlace filter options that can be downloaded?

Nebulosity can - can also capture images from DSI....

I've been re-processing the Neximage pictures I captured last full moon. This time with less severe wavelet processing. I also started with a bigger sample of raw frames this time and finished off with deconvolution filter in Astra Image just for fun...

and here's the DSI image after deinterlace filtering in GIMP

wow , nice full moon , first time i tried a full moon i was well out of focus buy you seem to have caught this very well, thanks for sharing it with us .
not had any decent weather in the uk for 10 days

Hi Peter,
your first picture looks like 3D
it reminds me on my first moon picture,
made many tens of years ago
be proud for it, so I was at that time
