I picked up a 16" New Moon a few months ago and am really enjoying it so far but there are a few things I am wondering about.
1. I'm familiar with cooling the mirror prior to using it, but when it's warmer outside, do you still need to allow time for the mirror to acclimate or does it not matter if the mirror is colder than the ambient temperate?
2. Do you guys put some sort of cover over the secondary mirror to prevent dust when not in use? The person I bought mine from just had a zip-lock bag around it. Any issues with continuing to do that?
3. I have a SIPS coma corrector. I know the regular Paracorr has a 1.15x barlow effect. Does the SIPS do this as well?
4. Do you put the SIPS in before or after collimating? I've noticed that the Glatter collimator can hit the SIPS if I don't move the focuser out a bit, which got me wondering if I am even doing this correctly.
4. The other day when collimating the primary, I had to turn one of the screws all the way in. It brought it right to where it needed to be, but if I had to go any further, I wouldn't have been able to. This is the first time this has happened. Does this mean the mirror has somehow shifted out of position? How do I get this back to normal?
5. Are the Catseye tools considered more thorough collimation than a Glatter and Tublug, or would it be superfluous to buy them since I already have the Glatter & Tublug?
6. When using ServoCat, it usually gets me in the neighborhood but I still have to search around a little. Is this normal or am I doing something wrong? I made sure to set up my location on Argo Navis. Does doing the alignment with two stars that are far away make goto more accurate?
7. I'm sure 16" of aperture is overkill for solar observing, but is there any reason not to make an off-axis solar filter for this other than storage space?
8. When I'm done and bring everything inside, the mirrors and eyepieces fog up, so I leave them out and wait for the glass to clear up before putting the cover back over the mirror and the eyepieces in their case. I don't have a garage or any other room where I can make the warming up more gradual, so is there a better way to do this than what I am currently doing?
9. When tracking with ServoCat, I sometimes find that at really high magnifications, the scope moves at a slightly different speed than the object I am looking at. Is there a way to make this more accurate or is this just the nature of the beast when using high magnification?
10. I am planning on taking the scope on a road trip from NJ to New Mexico in September during which I will camp in a pickup bed on the way there and back. The scope doesn't fit through my truck's doors, so I bought a padded, weatherproof bag to transport it in the bed. Is it a bad idea to keep the scope outside (but in the bag) for a week or two at a time? I'm sure keeping the bag zipped up will prevent dew and slow down temperature fluctuations, but I'm sure there will still be SOME temperature change taking place inside the bag, especially in the desert. Should I be concerned about this or am I overthinking it?
Thanks for any help, I'm still learning but have already learned a ton from reading this forum!
