Excellent write up Steve, many thanks! -
Lots of lovely little Seagulls. 130 PDS and Collimation

Could be pinched optics, it might be worth checking the tightness of the primary mirror clips. The mirror should be able to move slightly - when tightening the screws, a lot of people put a little bit of thin card inbetween the clip and the mirror, then remove it to leave a very small gap. It may be that the camera picked up the problem but the mk1 eyeball missed it. Always worth checking anyhow. -
Just picked up on this thread Neil - fantastic job, well done sir! ?

Howden Reservoir MW - Richard Lawrence-Day.jpg
RichLD commented on RichLD's gallery image in Imaging Challenges
Shot under the light polluted skies of Howden Reservoir, I've tried to tease out as much of the MW as I can without going too OTT - this spot (53.4426 N - 1.7484 W, 282m elevation) would normally be under around 2 meters of water! ? Mars is visible just above the tree line on the left. Vertical 2 frame panorama stitched in PS. Canon 6D, Samyang 14mm f/2.8 wide open. The top 80% or so of sky is made up of 10 frames captured using an iOptron Skytracker - ISO 2500, 30s, registered and stacked in PI. Foreground and bottom 20% or so of horizon/sky is a single shot at ISO 800, f/11 30s exposure. Thanks for looking! -
This could be due to the lens being an EF-S variant (for crop sensor only). They protrude further past the flange than EF lenses. You can't use the EF-S lenses on a FF camera because they foul the mirror. I have two of the Geoptik Canon adapters and have no issues using 2" filters with EF lenses. HTH Rich

For me the pros for OSC are (in no particular order) size and weight, price, convenience and, in the field, ease of use (there's one less thing to go wrong as there's no filter wheel). As Olly has said before, the speed of capture is technically faster with mono and filters and the processing for OSC can be a real pig IMHO. I have 2 monos and 1 OSC. The OSC can take great shots in a very neat and tidy package (great for when I haul everything to a dark site, which is when the OSC comes into its own) but for every other situation the mono wins hands down. Just my 2 cents HTH Rich

Mainly WIP, but that's a given, weather in the UK and life getting in the way! HEQ5 used for all capture. Orion's sword HaRGB, first taken with dual rig - QHY9M + Nikkor ed180 + Baader 7nm for HA, QHY8L + SMC Takumar 200 for RGB. M42 and B33 detail added from QHY8L and SW ED80 (approx 1 hour each plus lum on B33 from DSW) Base image around 2 hours so far... M31 captured with QHY8L + SW ED80 Cygnus HA 9 panel mosaic WIP captured with QHY9 + Nikkor ed180, Tamron SP90 and Pentax 135, Baader 7nm Elephant Trunk and Flying Bat HA captured with QHY9M, Nikkor ed180 and Baader 7nm

Gina, please excuse me if I sound really thick here, but is that ice on your sensor?
