Re: Killing or removing a cockroach
Don't use any chemicals. Instead, check the instruction manual for info
on how to remove the corrector plate. Remove the roach, then replace the plate with all possible care. Just my advice. In the future, always keep the focuser covered, since the roach surely had no other way to get in. Roaches are wonderful and amazing creatures, but we don't want them in our telescopes!

If you have the scope with the removable secondary just take it out and point the scope down. I would get it done? before he starts doing his business. Gary Carpe Noctem Sent from my space ship via my LG V10 Phone

Killing or removing a cockroach
I recentely attached an old Crayford focuser to my C-8, Last night when setting up I noticed a cockroach crawling over the inside of the corrector plate. Anyone have any ideas on how to extract, kill, remove the cockroach I have some gel-bait based on boric acid but I'm not sure it's a good idea to use the near coated optics. Should I I remove the corrector and clean the corrector and mirror as a precaution?

New C14 EdgeHD!
Well, I finally pulled the trigger on a new HD. I have been using the "old" model C14 for years and thought it was time for an upgrade. At any rate I have one question for those out there with these models. What is the best way to cool these beasts? It was obvious last night when I tried to image for the first time that it will NOT cool itself! I ordered a "Cool Edge" from Starizona but didn't try it yet. Are these effective? What are other alternatives. I really don't want to ship it off for fans to be installed unless I have to. Thanks! Brian |

Re: Possible outgassing - questions
Gary Jarrette
Ok Thomas
Just trying to come up with some with some scenarios that could account for the condition your mirror is in. I am sure you are aware of how difficult it is to make a diagnosis with information supplied by someone on the internet. The good thing is that there is so much experience to draw from some good some bad. You will have to be the final arbiter of that The last comment on cleaning the mirror was a good one but I “personally” would remove the mirror. If you have removed the corrector you are half way there. Going the extra distance is not that much more of a task. Reaching in to clean the surface of the mirror makes it much more difficult. I can understand the reluctance to dissemble and its appeal but in reality going the extra distance to remove the mirror is really not that much more difficult. It involves removing a nut on the focus knob and an “0’’Ring” on the baffle tube, after that you just pull the tube and the mirror comes out with the tube. This also gives you opportunity to clean off and re-grease the baffle tube with fresh grease alleviating your concerns about outgassing and if the scope is several years old it is probably a good Idea anyway. There are several good videos on YouTube about cleaning optics and mirrors. As was pointed out in the previous post use copious amounts of swabs or cotton balls and not the synthetic type, use real cotton. Also final rinse with distilled water. A note of caution. Aluminized mirror coatings are much softer than lens surfaces so do not rub. Continuously use fresh cotton and keep it wet. Wipe away from the center and no circular motions. Drag the cotton do not apply pleasure. Mirrors are easily scratched as they are relatively much softer than lens coatings and both should be cleaned gently for maxim longevity but you can do it as it is not all that difficult. Remember to reinstall the corrector in the exact position that it was in prior to removal. It might be a good time to check to see if your nut on the secondary mirror holder is tight and perhaps replace the fiber washer with a new rubberized one from Starizona. The OEM washer dries out and can cause the secondary mirror housing to rotate so this would be a good time to replace it. Well that is about it. I believe we have sufficiently beaten this dead horse. Let us know how you make out? Gary Carpe Noctem Sent from the Astro Cave via my MS Surface Tablet From: C14_EdgeHD@...

I Iooked at the picture of your mirror again and noticed something peculiar. It looks like this haze on your minor, if deposited by something that is released into the air space inside the OTA, is it not deposited evenly on the whole surface of the mirror. If the picture is correct you have area, a ring or band if you will where there is no deposit, just the central region is hazy. This is very peculiar. If something was floating around in the OTA like dust or particulate matter of any type it would not be selective in its deposition. It would coat the entire surface evenly, so this leads me to wonder if maybe you store your scope pointing down. This is just a theory but if the mirror is looking down like a bowl upside down and grease is melting and getting past the hole in the mirror around the baffle tube it could flow out evenly from the center of the mirror. This could account for it not reaching the outer edge of the mirror, YET. Do you store your scope facing down? Has it been stored facing down setting on the ground, shelf, or other such surface in a relatively warm or hot area like a garage for any extended period of time at elevated temperatures? One last thing.. Are you sure this is not a reflection? Gary . < =15045/stime=1454729567> < 9&js=no&resp=img> |

Re: Possible outgassing - questions
开云体育Hi Yasushi,
Thank you so much for documenting your process in images. If I get up the courage to open the scope I will be there with my camera as well. I am wondering if someone with a long thin arm could reach down to the primary mirror through the corrector plate center hole. Clear skies, Thomas On 2/6/16 6:35 29000, yfukunag@...

Re: Possible outgassing - questions
Hi Thomas, My EdgeHD1400 is 4+ years old and not only the corrector plate also the primary mirror has had a great amount of dust on the surface. I have suspected it was primarily due to water residue because I have often used the scope in the very humid environment and that the dew that condensed on the mirror drew the striped pattern on the surface thanks to the gravity. Also suspected the dew came through the rear cell air vents. A few weeks ago I decided and cleaned both the corrector plate and the primary mirror. Cleaning the mirror was a bit challenging; since I did not want to cause any mechanical error because of any unnecessary dismantling I cleaned the mirror without the carbon tube being removed from the rear cell.? I cleaned the mirror with neutral detergent and tons of cottons, softly swiped and used new cotton with detergent for each swipe. After the cleaning, I rinsed the mirror with shower carefully so that I would not throw water backside of the mirror or onto the baffle tube (especially on the part with grease), and threw some purified water to the mirror to finish the cleaning. Overall it worked out but I should have put a cover on the baffle tube to prevent from water using a plastic bag and a rubber band to hold it. Hope this somehow helps. https://picasaweb.google.com/103800208488106107896/EdgeHD1400PrimaryMirrorCleaning# Regards, Yasushi Fukunaga |
