SkyWatcher 180mm Mak first light

#1

Post by Bigzmey »


11/27/2021

Location: home, Bortle 6.0
Equipment: SW 180mm Mak and Stelarvue 102ED on iOptron AZMP, EPs: TV Delites set, Baader Aspheric 36mm, ES62 26mm.

Had a chance to do a field test of my early Christmas present - SW 180mm Mak. Here it is riding side by side with SV102ED on the iOptron mount, with and without shiny armor. :)

I am happy to report that the insulation seems to work. Mak was able to handle high powers immediately after deployment.

19:00. Saturn
I have started with the planets. Overall, this year was disappointing for Saturn. However, this time the view with Mak was surprisingly good. I was able to take it to 386x with TV Delite 7mm. The view was soft but Cassini division and multiple bands on the glob were resolved. SV102ED at 238x with TV Delite 3mm delivered smaller and sharper view but with less details on the globe.

Jupiter
GRS was transiting, but the view was not the best. GRS was barely resolved in both scopes and while fine details in multiple belts were visible at the moments of better seeing, overall contrast was low in both scopes. SV102ED/Delite 3mm (238x), SW Mak/Delite 11mm (245x). Baader Moon and Sky Glow + Contrast Booster filters combo was used in both scopes. I played more with EPs and filters and achieved better definition of belts and GRS in Mak with BCO 10mm (270x) + Baader Blue 470 bp. Even the Red Spot Hollow was resolved.

I did a brief star test on Polaris. In the outward defocused image, the central obstruction shadow was slightly up off center, and slightly below center in the inward defocused image. Unfortunately, the seeing was too bad to resolve airy disks. Next day I have looked for SW Mak collimation instruction and found one for Orion. Close enough. :) They recommend to do/check collimation during daylight. I followed their instruction to check collimation and as far as I can tell the scope is collimated without diagonal. However, with two different diagonals the shape of the primary mirror image was slightly oval. I wonder if slight misalignment of optic train is introduced by 2” visual back. It does not have compression ring, just two screws at 4 and 8 o’clock positions. I will look for a better visual back and will not mess with collimation for now. Perfect is the enemy of good. :)

20:00. Asteroids
It has been a while since I have caught any asteroids and quite few new moved into view. All observed with SW 180mm Mak (since it has lbig aperture advantage over the 102mm SV frac) using ES62 26mm (104x).
ast 112721.jpg
There were a few others within the reach of 7” scope. Unfortunately, Auriga and Taurus harboring those have not cleared the large ash tree north-east from my observing spot.

Orion doubles
20:45. I decided to split a few doubles. Orion was in a nice clear spot; I was typing the first double into SkySafari when my mount went offline. Apparently, it has run out of battery juice. I may need to replace it. Luckily, my son got a large power cord wheel this summer. I grabbed it from the garage and run the cord from the house to the observing spot. The mount went back online and after alignment and connecting it to the SkySafari on my phone we were back in business! :)

21:15.
STF 597 – 8.8, 12.2, 30.4”, white, silver. Secondary was a sharp dot in SW Mak/Delite 13mm (208x) and soft averted vision spot in SV102/Delite 3mm (238x).

HJ 684 – 8.6, 10.3, 9.6, 12.5, 9.6, ab24.8”, ac46.4”, cd11.9”, ae78.1”, A, B, C and E – white, D – silver. SW Mak/ES62 26mm (104x).

STTA 55 – 8.2, 9.2, 37.4”, pale orange, bluish. Nice colors in both scopes. SW Mak/ES62 26mm (104x); SV102/Delite 18.2mm (39x).

H 6 83 – 7.2, 10.1, 95.3”, white, silver. Nice sharp views in both scopes. SW Mak/ES62 26mm (104x); SV102/Delite 18.2mm (39x).

STF 605 – 10.9, 10.9, 11.6”, silver pair. Brighter and sharper view in SW Mak. SW Mak/ES62 26mm (104x); SV102/Delite 7mm (102x).

STF 609 – 8.8, 9.1, 2.9”, yellow pair. Tight clean split in both scopes. SW Mak/Delite 18.2m (148x); SV102/Delite 5mm (143x).

STF 612 – 8.3, 8.4, 13.3, ab16.1”, ac59.8”. AB – orange pair – SW Mak/ES62 26mm (104x); SV102/Delite 18.2mm (39x). C – gray dim spot resolved with averted vision in SW Mak/Delite 5mm (540x).

Overall, I really like the optical performance of the SW 180mm Mak. It produces APO refractor like views with high contrast and sharp colorful stars. I was also pleasantly surprised with its ability to go to high powers without image deterioration.

This is a great first light report!
And worth a VROD! If not I'll eat my hat.
From now on, the word "seems" can just be crossed out in sentences like "insulation seems to be working in Maks".
The Red Spot's hollow is a difficult object in all minus 8 inch telescopes. Congratulations on having seen it!

Hi. Do you recall what the indoor and outdoor temps were when you took the scope out? Humidity as well? Also, as the evening progressed do you feel the views stayed consistent or did they get worse or better? Thx.

Very nice report Andrey and definitely worthy of the VROD as nominated by John, look for the additional bling to show up on 12-2, barring any home run reports submitted by other members. Today's award was granted to Harshil who submitted his report after an observing hiatus - his first VROD.

Thanks nFA, John, Harshil, Tony, Michael and Marshall! You will definitely see more reports from me and my CATs. :D

@WilliamPaolini California temperature swings are relatively mild compared to some other places. The scopes went from ~68F (20C) inside the house to ~77F (25C) outside. Yep, that's SoCal winter for you. :) Over the course of the session the temp dropped to ~52F (11C). From what I can tell the views in Mak stayed consistent. I will follow up on the effects of insulation since from now on I am using it on all my CATs.

Wow, great report Andrey, nice set up and location as well!

That really seems to be a great scope, and at f/15 to boot. Nice :D Perfect is the enemy of good, I've never heard that expression before; I quite like that. Hopefully you get it sorted out with the image through the diagonals.

I'm wondering too, where did you get the "shiny armor" for your Mak, or did you make it? I'm curious for my SCT, as the temps here lately are room temp to +35F at best outside.

Good to hear the scope serves you well, and I third the nomination for VROD ;) Nice list of targets; I'm envious :lol:

All the best,
Mark

Great report Andrey!

Maks are certainly awesome scopes, I have the 127, always wanted the 180.

I have learned not to fret about collimation through a diagonal. If it's good without, then I'm good to go :)

(This is more frequent with the SCTs.)

Thanks. Not my environment in the slightest. For me winter observing means scope going from indoor temp of 70 F to outdoor temp of 20 F with humidity around 50-60%.

Thanks Juha. It is fun! :D I like to pair scopes which supplement each other. In this case 102mm frac for low power wide views and 180mm Mak for going deep.

Maks are certainly awesome scopes, I have the 127, always wanted the 180.

I have learned not to fret about collimation through a diagonal. If it's good without, then I'm good to go :)

(This is more frequent with the SCTs.)
Thanks Jeff! Sometimes it is not diagonal or scope but something else (focuser, visual back, etc.).

@WilliamPaolini California temperature swings are relatively mild compared to some other places. The scopes went from ~68F (20C) inside the house to ~77F (25C) outside. Yep, that's SoCal winter for you. :) Over the course of the session the temp dropped to ~52F (11C). From what I can tell the views in Mak stayed consistent. I will follow up on the effects of insulation since from now on I am using it on all my CATs.
Thanks. Not my environment in the slightest. For me winter observing means scope going from indoor temp of 70 F to outdoor temp of 20 F with humidity around 50-60%.
The general principle should still apply, maybe more layers of insulation?

Yes, the general principle here is that the insulation is slowing the cooling (assuming the scope started in a hotter environment). So in that slowing there are less dynamic eddies in the OTA as it does cool. The insulation cannot completely insulate the OTA however as the thin corrector plate will not be insulated and cooler air will interact. Same for the back of the OTA and the diagonal. So these are the weak points in the insulation approach. So overall will lessen the thermal instability but not stop it of course. In more aggressive environments like mine it should be less tamed than you are seeing therefore.

There are a lot of variables, and the back of the OTA and diagonal can become very sensitive. When I did my tests of thermal stability of an 8" SCT I got my OTA completely thermally acclimated outside in temps if I recall correctly were 20 F or less. Once it was stabilized I could observe (critical planetary) for no more than 15 minutes. After that enough of my body heat transferred to the OTA that the views became unstable for critical planetary. I would them walk away from it for 15 minutes to allow it to re-stabilize, then was able to get another 15 minute observation in. In these tests I had my Apo setup as well so had confirmation that the new instability I was observing was from the scope and not the seeing (IMO always need a reference scope when doing these types of tests). So the back of the SCT OTA is very sensitive to unavoidable body heat (i.e., face or any contact with un-gloved hands) when the outdoor temps are very low. So I know folks in certain environments where the insulation does a pretty good job, and does no good for others. So it indeed works within environmental limits. And since the engineering is different on the various brands of SCTs and Maks, how well they take to insulation will differ as well.

A few people have ATMed the solution differently and have kept their OTAs closed but put fans to aggressively circulate the interior air so all the eddies internal keep a fairly constant temp and therefore do not cause any instability to the view. A novel approach that seems to really tame the issue regardless of the environment. But that approach involves drilling holes in the OTA and installing surface "nacelles" so the fans can pull internal air from one end and deposit it at the opposite end. Not something I would want to do.

Anyway, congrats on your new scope and glad it is working out well :handgestures-thumbup:

Yes. I know some folks here are very happy with the insulation approach. I prefer forethought and cold soaking.
