silentrunning Posted October 12, 2020 Share Posted October 12, 2020 I recently purchased a Samyang 135mm f2 lens as I fancied a change from the very narrow field of my 12" RC. The lens in combination with the large chip of the QHY11 gives a very wide field of view and the ease with which guide stars can be found through a dedicated guide scope rather than an OAG has allowed me to venture into mosaics. This is a three panel mosaic of The Pleiades and The California nebula demonstrating the stark contrast of the blue reflection nebula surrounding The Pleiades and the strong red emission lines of the California nebula. This was 3x10 min binned 1x1 Ha and OIII for each panel. Calibrated and merged in PixInsight with some final processing performed in Affinity.Click on the link and then the image for a large format version.John https://www.astrobin.com/nriebd/0/ 8 Quote Link to comment Share on other sites More sharing options...

Dmack1 Posted October 12, 2020 Share Posted October 12, 2020 I really like that framing. The contrast of colours is wonderful 1 Quote Link to comment Share on other sites More sharing options...
PaulB Posted October 12, 2020 Share Posted October 12, 2020 I like that very much. This is an excellent camera lens that is ideal for widefield CCD imaging. 1 Quote Link to comment Share on other sites More sharing options...
geoflewis Posted October 12, 2020 Share Posted October 12, 2020 You know John, I've look at this image a few times now and the more I look the more I like it. Well done persevering with this project.Geof 1 Quote Link to comment Share on other sites More sharing options...
Stub Mandrel Posted October 12, 2020 Share Posted October 12, 2020 That's really nice.I have an old but very good Zeiss Sonnar 135mm that has taken some nice pics with my DSLR and I must make an adaptor to use it with my ASI1600MM. 1 Quote Link to comment Share on other sites More sharing options...

I had to build a number of adapters for both sides of the the FW - the lens and the camera sides - to get the lens to chip distance down to what's required for this lens. A lot of work but beginning to pay off. Quote Link to comment Share on other sites More sharing options...
silentrunning Posted October 12, 2020 Author Share Posted October 12, 2020 @geoflewis Must admit Geoff it is growing on me as well, it might even by my desktop for a time. Bit of a turn around from being close to giving up on it. 1 Quote Link to comment Share on other sites More sharing options...

don4l Posted October 13, 2020 Share Posted October 13, 2020 Very nice. That's a lovely image which really makes excellent use of the huge FOV. The panels appear to have come together seamlessly. 1 Quote Link to comment Share on other sites More sharing options...
