Thanks for all your replies. I actually used a blue sky background to find the initial problem as I was finding consistent spots in every photo. The streaking has certainly been a Heart in Mouth experience. Can I ask please – using pec pads wrapped around the old swabs – I read somewhere not to use pec pads on sensor, but it seems to be commonly done. How many drops of fluid would I put on the pad once attached to swab? The photosol article I found recommended up to 8 drops of the eclipse fluid on the swab for the a 24mm size and oddly said the more the merrier for getting rid of streaks from first clean! I think this will be too much. I have some pec pads available and could give this ago. I have swapped to my D500 until I get it sorted. Dave re dome maintenance – I can get the micromesh set from Australia within a month (the joy of living in the South Pacific – have to wait for everything). I have watched a few videos this afternoon and it all looks ok for me to try. Is it one micromesh set per dome? I get the impression that the sheets can be halved? My 8.5 inch acrylic dome needs some TLC . We have another dome that needs some work on the inside – it is an N85 (short story – my wife’s new kit was shipped made up with camera / lens in housing and port on – lens cap came off during shipping and had a party on the inside of the dome – nothing deep but lots of fine scratches and the base is so small I cannot get my hand in it - but Sandy can! It may be a a case of trying the Novus on this one) Cheers and thanks all.

May as well get a topic up and running! I guess now that we have a new forum it is appropriate to start topics anew! I recently acquired a second hand D850 and found the sensor had a few marks that were noticeable in photos. After contacting the seller I was told that he had used photo solutions products and recommended the Eclipse fluid. Due to freight restrictions I have only been able to get a photosol digital survival kit which includes the less flammable Aeroclipse solution. I have used the correct size ultra swab (No. 3 - 24mm) for full frame. The kit I bought had 4 swabs So yesterday I took the plunge, watched several you tube clips and followed the directions to the letter. Now -- after the first go -- some improvement but horrendous streaks --- after 4 tries I have had to give up as no more swabs left in the kit but the darn streaks are still noticeable. I can source some to be here in 3 weeks. I have attached 3 photos - a start, second clean and now - noticeable dirt in the first, second clean heavy streaks and by the 4th go less streaking but still noticeable. It is as if sensor "dirt" has smeared - pretty sure not scratches. A photosol article I found suggested using more fluid which seemed counterintuitive. Camera now unusable and I am debating: 1. try again once I can get some more swabs, 2 pack it up and send to Australia for cleaning Anyone had a similar experience, is it just my technique that was wrong or have I stuffed the sensor!! Bit worrying! This afternoon I am cleaning a scratched acrylic dome using novus cleaning kit and now worried I will stuff that up too (mental note to self when asked to do spilt shots for a resort to show their new paddle boards - don't let the staff paddle them into you and hit yoour dome!) Cheers John

Mine has never let me down on D500 or D850

Here here !!

Hi - John from Vanuatu, a fairly regular user and certainly daily observer moving across from Wetpixel. I have been based in Vanuatu for 23 years and lucky enough to have a house reef as our front yard. My wife Sandy and I dive every week here and my passion is macro, Sandy's is video. Currently shooting a D500 and D850, Sandy now learning the GH5ii. We have just started a boutique dive operation for small groups, called Critter Spotter (can be found on both IG and FB) - as the name implies our aim is to take divers to see (and photograph) the small stuff! We also have a FB group dedicated to Vanuatu UWP and diving called ,surprise surprise ,"Underwater Vanuatu". These forums have been a fantastic source of information for me over the years and much of hat I have learned has been through the terrific community of UW Photographers that contribute so willingly. Hats off to all the admin team for getting this going! Cheers to you all
